-Double clicking on width or height spinner resizes both, but scales to the one double clicked.
--Bug fixes
-Show grid setting was not being preserved during program run, only on close.
-Zooming with the mouse wheel was broken for images whose size is greater than the screen area.
-No longer constrain pitch, yaw or depth spinners to -180 - 180.
--Bug fixes
-Properly set color index on padded xforms.
-Adding a padding final xform included a linear variation with a weight of zero to not appear empty. Made it have a weight of 1.
-Always write animate tag on final xform when saving to Xml.
-Motion was being applied to the wrong flame in SheepTools::Edge(), so apply it to the correct one.
-Prevent divide by zero when normalizing variation weights.
-Was accidentally adding the placeholder value of -9999 for motion_offset to varation weights and parameters when applying motion. Set to zero if no value present.
-Clamp flame rotation values to -180 - 180 when reading a flame from Xml.
-Events were not properly wired for user changes in the random rotations per blend controls in the sequencer.
-Fix major UI bugs with sequencer min/max random controls which made it nearly impossible to hand type values.
-Values from rotations per blend and rotations per blend max were not being saved to file between program runs.
-Checking animate for an xform was not applied to all flames even if Apply All was checked.
-Changing interpolation type, temporal filter width, temporal type, and affine interpolation type were not actually saving to the flame when changed.
-Grid on the main window was not being drawn at the right scale initially due to some OpenGL initialization occurring in the wrong order.
-Severe bugs in sequence generation code:
--Improperly detected padding xforms.
--When looking for specific variations during xform aligning, only presence was detected, when it should have been presence plus a weight greater than zero.
--When adding specific variations during xform aligning, must first remove any variations of that type.
--Two variables were unsigned when they should have been signed. This prevented large blocks of code from ever executing.
--When interpolating affines, an EPS that was too small was used, causing affine values to interpolate incorrectly. Instead use 1e-10 to ensure results equal to flam3.
--Code changes
-Modify FractoriumEmberController::UpdateXform() to pass the selected xform index as well as the absolute index to func().
-Allow running from outside of the folder the executable is in on Windows, by adding the install folder to the PATH variable. This was needed to properly find the palette file (even though it's mostly unneeded).
-Add two new variations, hyperbolic and hypershift2.
-Allow for animating final xforms.
-More detailed diagnostics when any action in the OpenCL renderer fails.
-Allow for creating an OpenCL renderer which does not share a texture with the main window, and instead manually copies its final output image from GPU to CPU then back to GPU.
--Bug fixes
-Text was not properly being copied out of the Info | Bounds text box.
--Code changes
-Remove Renderer::AccumulatorToFinalImage(v4F* pixels, size_t finalOffset), it's no longer needed or makes sense.
-Controllers no longer keep track of shared status, it's kept inside the renderers.
-Make getter functions in FractoriumOptionsDialog be public.
-Allow for pausing and resuming of final renders.
--Code changes
-Only instantiate float version of Palette and PaletteList, no need for double since it's never used.
-Allow for FinalRenderDialog to be queried on whether it's currently rendering.
-Convert OpenGL drawing code to use GLSL. Leave #define in until testing on multiple platforms is done.
-Always use double precision extension defines in OpenCL programs, even if DP is not selected. This is because elliptic now always uses DP.
-Allow 7 decimal places in variations spinners.
-Try to prevent infinite loop that sometimes happens when drawing grid. Unsure if this actually works since it's very hard to reproduce.
-Update /debian/changelog to use a newer version of ubuntu named artful. Users will need to add that PPA to get it via apt.
-Update copyright year to 2018.
-Allow group dragging and floating of dock widgets.
--Note this has a bug where if tabls are grouped while floating, the tab position is placed on the bottom. It restores to the top when dropping on a dock location. I've filed a bug at qt.io
-Make some tables auto size to their contents because some text appeared obscured on Linux.
-The size of the xforms and palette tabs were preventing the main window from being resized to a small size on lower resolution monitors when docked. So rework scroll areas, minimum sizes and layouts to allow for a smaller main window.
-Support 4k monitors, and in general, properly scale any monitor that is not HD.
-Allow for a spatial filter of radius zero, which means do not use a spatial filter.
-Add new variations: concentric, cpow3, helicoid, helix, rand_cubes, sphereblur.
-Use a new method for computing elliptic which is more precise. Developed by Discord user Claude.
-Remove the 8 variation per xform limitation on the GPU.
-Allow for loading the last flame file on startup, rather than randoms.
-Use two different default quality values in the interactive renderer, one each for CPU and GPU.
-Creating linked xforms was using non-standard behavior. Make it match Apo and also support creating multiple linked xforms at once.
--Bug fixes
-No variations in an xform used to have the same behavior as a single linear variation with weight 1. While sensible, this breaks backward compatibility. No variations now sets the output point to zeroes.
-Prevent crashing the program when adjusting a value on the main window while a final render is in progress.
-The xaos table was inverted.
--Code changes
-Convert projects to Visual Studio 2017.
-Change bad vals from +- 1e10 to +-1e20.
-Reintroduce the symmetry tag in xforms for legacy support in programs that do not use color_speed.
-Compiler will not let us use default values in templated member functions anymore.
--Bug fixes
-Strips renders crashed.
-Better handling of large memory allocations by forcing a free of previous allocations.
-Final render dialog did not properly save last used extension setting.
-Density filtering progress bar in final render dialog did not update if only log scaling was being used.
--Added panorama1 and panorama2 variations.
Bug fixes:
--crackle had a bug with Nvidia GPUs.
Code changes:
--crackle now uses real_t* for cache rather than real2. This is what was causing the bug.
--Make the local offsets array used in crackle a precalc since it's the same for all. This reduces register pressure.
--Get rid of all usages of real3, just to be safe since Nvidia doesn't like them.
--#define TOTAL_GLOBAL_SIZE_END in the OpenCL iteration kernel just for debugging purposes to see how large the parvars buffer is.
--Disallow the use of synth when randomly generating xforms if the user has an Nvidia device present on their system.
Code changes:
--Use some CPU defines in CL code.
--Change curves color scaling buffer to be 2^16 per channel instead of 2^17 which was probably overkill.
--Code in RendererClDevice::Init() to detect Nvidia was wrong even thought it technically worked.
--Add support for Exr files which use 32-bit floats for each RGBA channel. Seems to come out too washed out.
--Allow for clearing an individual color curve.
--Allow for saving multiple image types in EmberRender and EmberAnimate. All writes are threaded.
--Remove --bpc command line argument. Add format png16 as a replacement.
--Remove --enable_jpg_comments and --enable_png_comments command line arguments, and replace them with --enable_comments which applies to jpg, png and exr.
--Add menu items to variations and affine spinners which allow for easy entry of specific numeric values like pi.
--Make final render dialog be wider rather than so tall.
Bug fixes:
--Fix some OpenCL compile errors on Mac.
--Remove ability to save bitmap files on all platforms but Windows.
Code changes:
--New dependency on OpenEXR.
--Allow Curves class to interact with objects of a different template type.
--Make m_Curves member of Ember always use float as template type.
--Set the length of the curves array to always be 2^17 which should offer enough precision with new 32-bit float pixel types.
--Set pixel types to always be 32-bit float. This results in a major reduction of code in the final accumulation part of Renderer.h/cpp.
--Remove corresponding code from RendererCL and FinalAccumOpenCLKernelCreator.
--Remove Transparency, NumChannels and BytesPerPixel setters from Renderer.h/cpp.
--Add new global functions to format final image buffers and place all alpha calculation and scaling code in them.
--Blending is no longer needed in OpenGLWidget because of the new pixel type.
--Make new class, AffineDoubleSpinBox.
--Attempt to make file save dialog code work the same on all OSes.
--Remove some unused functions.
-Attempt to fix several OpenCL build errors that were occurring on Mac.
--Code changes
-Improve the coloring code during final accum by getting rid of the last remnants of unnecessary scaling to 255 from flam3.
-Begin work of supporting 16bpc on the GPU.
--User changes
-dark.qss is now per-OS.
-Properly set/reload palette when coming from the palette editor. The latter must be done if they've modified the current palette even if they've clicked cancel.
--Bug fixes
-Make the following variations safer by using Zeps(): conic, bipolar, edisc, whorl, tan, csc, cot, tanh, sech, csch, coth, auger, bwraps, hypertile3d, hypertile3d1, ortho, poincare, rational3, barycentroid, sschecks, cscq, cschq, scry_3D, splitbrdr, hexcrop, nblur, crob.
-Fix bug enabling/disabling overwrite button in palette editor.
-Small optimization for gdoffs, use precalcAtanYX.
-Properly propagate z through circlesplit, cylinder2 and tile_log variations.

--Bug fixes
-Fix crash when opening palette editor with a flame whose palette specifies no originating file.
--Code changes
-Revert font changes, only use qss for these now.
--User changes
-Make all fonts be MS Shell Dlg 2. This will require reloading dark.qss if users are already using it.
-Limit size of the left side of the palette editor.
-Disable create from image buttons in the palette editor when working on a fixed palette.
--Bug fixes
-The following variations were wrong: coshq, cothq.
-During iteration, the color index could become nan if all xform color speeds were negative. This could lead to bad results on the GPU. Fix to check for nan. Minimal speed difference.
--Code changes
-Make the following variations safer by using Zeps(): sinq, sinhq, secq, sechq, tanq, tanhq, cosq, coshq, cotq, cothq, cscq, cschq, estiq.
-Always pass -cl-no-signed-zeros -cl-denorms-are-zero to kernel compiles for both single and double.
-Flush all denormals to zero for all executable programs. This will likely lead to a speedup for badly behaving programs.
--User changes
-Add support for adjusting xform color indices in the palette editor. Fixed palettes can now be displayed there, but they will have no color arrows as they are not editable.
-Add support for independent dimension scaling in the EmberRender and EmberAnimate programs to bring them in line with the final render dialog Fractorium.
--Bug fixes
-File paths with a space in them did not work in the command line programs.
-Any Xml file in the search paths would erroneously be treated as a palette file.
--Code changes
-Change some for loops to while loops when iterating through xforms.
-Allow FractoriumEmberController<T>::UpdateXform() to be able to apply the action to an xform at a specific index.
-Remove old code blocks build files that were never used.
-Make GetPath() return empty string if no path is present in the passed in file path.
-GetTotalXform() was always counting the final xform, even if it was unused.
--Bug fixes
-Fractorium would occasionally freeze after dismissing the final render dialog because some values were not properly re-initialized.
--Code changes
-Remove VS 2013 build files.
-Qualify sqrt with std:: in ColorTriangle.cpp
-Bump to version 1.0.0.3
-Remove all code for opacity adjustment, it's no longer needed.
-Small optimization on accumulating to the histogram on the CPU.
-Double clicking min/max DE filter spinners would not trigger a render reset if the other was non-zero. The fix has the downside of triggering a change event when scrolling even if the value is already capped. This is an acceptable tradeoff.
-Xaos has been wrong this entire time on the GPU because it was not selecting from the unweighted distributions on the very first iteration when fusing.
-Query matrices when drawing affines even if they are set not to be drawn because the values are used elsewhere.
-No longer need to move library items on a delayed timer when dragging and dropping.
-Fix strange spurious crash in library tab when switching between SP and DP.
-Compensate for severe Qt bug where dragging and dropping disjoint items in the Library tree would resort the dropped items in special situations.

-Allow toggling display of image, affines and grid.
-Add new variations: cylinder2, circlesplit, tile_log, truchet_fill, waves2_radial.
--Bug fixes
-cpow2 was wrong.
-Palettes with rapid changes in color would produce slightly different outputs from Apo/Chaotica. This was due to a long standing bug from flam3.
-Use exec() on Apple and show() on all other OSes for dialog boxes.
-Trying to render a sequence with no frames would crash.
-Selecting multiple xforms and rotating them would produce the wrong rotation.
-Better handling when parsing flames using different encoding, such as unicode and UTF-8.
-Switching between SP/DP didn't reselect the selected flame in the Library tab.
--Code changes
-Make all types concerning palettes be floats, including PaletteTableWidgetItem.
-PaletteTableWidgetItem is no longer templated because all palettes are float.
-Include the source colors for user created gradients.
-Change parallel_for() calls to work with very old versions of TBB which are lingering on some systems.
-Split conditional out of accumulation loop on the CPU for better performance.
-Vectorize summing when doing density filter for better performance.
-Make all usage of palettes be of type float, double is pointless.
-Allow palettes to reside in multiple folders, while ensuring only one of each name is added.
-Refactor some palette path searching code.
-Make ReadFile() throw and catch an exception if the file operation fails.
-A little extra safety in foci and foci3D with a call to Zeps().
-Cast to (real_t) in the OpenCL string for the w variation, which was having trouble compiling on Mac.
-Fixing missing comma between paths in InitPaletteList().
-Move Xml and PaletteList classes into cpp to shorten build times when working on them.
-Remove default param values for IterOpenCLKernelCreator<T>::SharedDataIndexDefines in cpp file.
-Change more NULL to nullptr.
--User changes
-Add many tooltips to help clarify functionality.
-Select multiple flames in library for del/move. Still only one allowed to be set as the current.
-Show checkbox for current flame. Remember this is not necessarily what's selected.
-User can now drag a square to select xforms, which keeps in sync with checkboxes.
-Remove --nframes from command line. Replace with new params: --loopframes, --interpframes, --interploops.
-Add two new options to EmberGenome: --cwloops --cwinterploops to specify whether rotation should go clockwise instead of the default counter clockwise.
-Add these to Fractorium as checkboxes.
-Apply All now also works for toggling animate flag on xforms.
-Options dialog now allows user to set whether double click toggles spinners, or right click does.
--Bug fixes
-Selecting final and non-final xforms, and then dragging the non-final did not drag the final with it.
-Selecting all xforms when a final was present, then deleting crashed the program.
-Remove support for ppm files in the command line programs, it's an outdated format.
-Switching between SP and DP kept reapplying the palette adjustments.
--Code changes
-Move build system to Visual Studio 2015 and Qt 5.6.
-SSE used during addition of points to the histogram.
-Remove last remnants of old flam3 C code and replace with C++.
-Remove unused code involving tbb::task_group.
-Make settings object a global shared_ptr singleton, so it doesn't have to be passed around.
-Make stagger a double instead of a bool.
-Save stagger values to settings.
-Random stagger was being set in the wrong place.
-Save rotation values as double rather than int.
-Add animation sequence creation to Fractorium.
-Add two new options to EmberGenome which are used when generating an animation sequence.:
--startcount: Add this number to the filename of each flame.
--padding: Override the automatically calculated amount of padding zeroes added to each filename.
--Bug fixes
-Prevent filenames in command line programs from using scientific notation when rendering a large number of frames.
-Fix tab orders to match newer GUI items which were overlooked in previous releases.
-Re-render previews if transparency value in the options dialog was changed. Re-rendering was previously only done if early clip or y axis up was changed.
-Use transparency when rendering thumbnail previews.
--Code changes
-Wrap EmberCommon.h in a namespace called EmberCommon.
-Move FormatName() from EmberGenome to EmberCommon.h/cpp
-Add a prefix parameter to EmberFile::DefaultFilename() to allow for creating a default filename for sequences.
-When showing the final render dialog, allow specifying where it came from: the toolbar or the render sequence button.
-Refactor all preview rendering code out into its own class hierarchy with overrides for the main window and the final render dialog.
-Remove all preview render cancelling functions, they are now built into the new class hierarchy and a new render will not start until the previous one is stopped.
-Add two new function ConstrainLow() and ConstrainHigh() which wrap constraining two min/max spinboxes to each others' values.
-Add a bool to FractoriumEmberControllerBase::CopyEmberFile() to specify whether to copy the main file or the sequence file. This is somewhat of a hack and was done in a rush.
-Add a bool to FractoriumEmberControllerBase::SetEmberFile() to specify whether to move the file rather than copy. This is used in FinalRenderEmberController and improves efficiency.
-Add wrapper functions for variations filter dialog settings.
-Add a new option --statevars to EmberGenome to list the variations which change state.
-Allow for filtering in the Variations Dialog based on the same types listed in the EmberGenome options.
--Code changes
-More correctly populate VariationList::m_ParametricVariations and VariationList::m_NonParametricVariations to account for variations which have params only used for precalc.
-Consolidate some of the code in VariationList which searches by name.
-Add new options to EmberGenome to better help assess which variations have certain characteristics. The options are:
--sumvars: Display the names of all regular variations which have the default behavior of summing their outputs and exit.
--assignvars: Display the names of all regular variations which have the non-standard behavior of assigning their outputs and exit.
--ppsumvars: Display the names of all pre/post variations which have the non-standard behavior of summing their outputs and exit.
--ppassignvars: Display the names of all pre/post variations which have the default behavior of assigning their outputs and exit.
--dcvars: Display the names of all variations which use direct coloring and exit.
--parvars: Display the names of all variations which have parameters and exit.
--nonparvars: Display the names of all variations which do not have parameters (weight only) and exit.
--Code changes
-Make VariationList vectors have const elements since no callers should ever change them.
-Add new function to VariationList to retrieve a const ref to the parametric variations.
-Move some search functions out of EmberTester and into EmberCommon.h.
-General code cleanup.
-Remove --time option for EmberAnimate, it was redundant with --frame.
-Make --enable_jpg_comments and --enable_png_comments just be bools that when present mean true, rather than having to specify =true.
-Add a new argument --ts for EmberAnimate to allow the user to specify the temporal samples value to use for the entire animation. Useful for testing.
--Bug fixes
-Properly seed rands in EmberAnimate when specifying --isaac_seed and using more than one device with --opencl.
--Code changes
--Small cleanup to flatten/unflatten all code.
--Make EmberOptionEntry<T>::operator() return a const reference instead of a copy.
-Highlight power is now on by default.
-Allow for adjustments on the Flame tab to apply to all open flames in the file.
-Add two new buttons to the color tab to randomize and toggle the xform color indices.
-Remove the --strip option from EmberGenome. It was useless and was likely just a carry over from flam3 during its early debugging stages when testing strips.
-Make randoms in EmberGenome have default dimensions of 1920 x 1080.
-Prevent --inter and --rotate in EmberGenome from rotating backward before the first flame since it doesn't really make sense.
-Ensure every loaded flame has at least one xform in it.
-Change dark.qss to hide dotted selection outline around checkboxes. Users must reload it to take effect.
--Bug fixes
-The saving of last.flame during editing was appending the file when it should have been replacing.
-It was impossible for EmberGenome to create a random flame. It can now be done by specifying no arguments: EmberGenome.exe
-Crossing in EmberGenome was not logging the performed actions to the edit Xml tag.
-Apply sub batch size and fuse count to template files used on the command line.
-Use new default filter types with template files.
--Code changes
-Use cerr in SheepTools instead of cout.
-Set m_SubBatchSize and m_FuseCount to default values in Ember::Clear().
-Clean up some command line options text formatting.
-Always force times of each flame to increase from zero when saving a file.
-Remove check for times when doing a sequence in EmberGenome because the original times are never used there.
--Bug fixes
-Multi-GPU synchronization was not actually thread safe and was likely doing less iters than requested. It is now properly synchronized.
--Code changes
-Optimize Interpolater by making it a non-static class by adding some members used for caching values during interpolation.
-Cache values in SheepTools as well, which was already a non-static class.
-General cleanup.
--Bug fixes:
-Fix crash when using smooth interpolation in EmberGenome.
-Print error and exit EmberGenome when sequencing if times are not
sorted.
--Code changes:
-Another attempt at Singleton. This reverts the design to what it was
before with a fix to the code that was causing it not to behave like a
singleton should.
-crackle is now 5-10 times faster as a result of using cached values as is done on the CPU. These were previously omitted due to a bug elsewhere in the code that was erroneously attributed to the crackle caching mechanism.
-Report precision in command line programs.
-Edits will not save back to the file in memory on render completion when preview renderer is running.
--Bug fixes
-dc_perlin was crashing on Nvidia when using SP.
-Duplicate images were randomly getting added to the file in memory.
-Crash when opening an Xml with less than 2 flames in it.
--Code changes
-Use raw array of floats in OpenCL for perlin noise, rather than float3/double3.
-Add some default cases to dc_perlin.
-Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
-The concept of "saving back to file in memory" has been removed. The current ember is saved back to memory whenever the render completes and the thumbnail will be updated each time.
-Command line programs now default to using double precision.
-The --bits argument has been removed and replaced with --sp to specify single precision. If omitted, DP is used.
-Remove the --seed option, it was never used.
-Remove the --sub_batch_size option, it has been part of the Xml for a long time.
-Remove --hex_palette argument for EmberRender, it only makes sense in EmberAnimate and EmberGenome.
-Set enable_jpg_comments and enable_png_comments to false by default. It was a very bad idea to have them be true because it reveals the flame parameters used to render the image which many artists guard closely.
--Bug fixes
-Continuous update was broken.
-Undo list was broken with new Library tab design.
-Force repaint on xform checkbox change to ensure circles are immediately drawn around selected xforms.
--Code changes
-Remove save to back to file in memory icon, document-hf-insert.png.
-Remove the option --intpalette to format the palette in the xml as ints. If they are not hex formatted, then they should always be float. This option was pointless.
-Cleanup some options text for the command line programs.
-Allow for dragging around flames in the library tab. This is useful for setting up the order of an animation.
-Make the opening of large files in Fractorium much more efficient when not-appending.
-Make the opening of large files in all EmberRender and EmberAnimate more efficient.
-Better error reporting when opening files.
--Bug fixes
-Get rid of leftover artifacts that would appear on preview thumbnails when either switching SP/DP or re-rendering previews.
-Filename extension was not being appended on Linux when saving as Xml, thus making it impossible to drag that file back in becase drop is filtered on extension.
--Code changes
-Move GCC compiler spec to C++14. Building with 5.3 now on linux.
-Use inline member data initializers.
-Make a #define for static for use in Utils.h to make things a little cleaner.
-Make various functions able to take arbitrary collections as their parameters rather than just vectors.
-Make library collection a list rather than vector. This alleviates the need to re-sync pointers whenever the collection changes.
-Subclass QTreeWidget for the library tree. Two new files added for this.
-Remove all usage of #ifdef ROW_ONLY_DE in DEOpenCLKernelCreator, it was never used.
-Add move constructor and assignment operator to EmberFile.
-Add the ability to use a pointer to outside memory in the renderer for the vector of Ember<T>.
-Make a lot more functions const where they should be.
-Better handling of crossed min/max DE filter values on the GUI.
-Changes to spatial and density filter values will no longer restart the entire render.
-Support reading cam_zoom from xml as zoom since JWildfire uses cam_zoom.
-Change drag n drop behavior: the default is now to append, hold Ctrl to overwrite.
-Set max value of zoom to 25 because it will crash with values around 28 or 29 due to numeric overflow when scaling quality.
-Update links in About Dialog.
-Rename some controls in Options Dialog.
-Move the color curves control to the Palette tab.
--Bug fixes
-Remove extra space in info tree text when dealing with a linked xform.
-Update summary xform name field whenever xform name changes.
-Get rid of selection border on summary tab xform tree cells.
-Only add variations from Xml that have a non-zero weight. There seemed to be spurious flattens coming from Apo with a weight of 0.
--Code changes
-Gutters are now a fixed size of 8 * supersample.
-Use stl data() member to get pointer to first element instead of &vec[0].
-Eliminate extra calls in renderer to ComputeBounds(), CreateSpatialFilter() and CreateTemporalFilter() to only be done at the start of a render.
-Another attempt at vectorizing LogScaleDensityFilter(). Vectorizes, but not sure if it helps.
-Some other loop optimizations in Renderer.
-No longer check temporal samples in response to some control changes, they are always 1 in the interactive renderer.
-Remove some warnings about interpolation type on first and last flames.
--Code changes
-Make DE block size always be 16x16, this should help stability on some Nvidia cards. No changes for AMD cards since they were that size already.
-Since the block size is now so small, do not reduce it further when supersampling.
-Clean up some variable names and documentation around OpenCL DE to be more clear.
-Make the default interpolation type be smooth.
-Correctly label interpolation types in the combo in the animation table on the Flame tab.
--Set the default combo index to be smooth.
-Attempt to prevent crash when selecting OpenCL in the final render dialog when unsupported hardware is present.
--This works by selecting the last known good device in the main window.
-Make usage of VarFuncs more consistent by moving some global functions there.
-Make CircleTrans1 a little safer by calling Zeps() on m_Sc during precalc.
-Begin prepping for 0.9.9.5 release.
-Really fix locking of affine scale.
--Code changes
-Remove dependency projects from the solution. Move to a project design where they are built once via command line and stored in a /Deps folder.
--Because of this, libpng is built as a static lib instead of a dll because that's what its command line makefile supports.
--Remove libpng16.dll from Wix installer.
-Remove all configs except for debug and release.
-Remove all platforms except for x64.
-Add #define __TBB_NO_IMPLICIT_LINKAGE 1 to prevent tbb from locking for tbb_debug.lib by default on debug builds.
-Put Ember.rc in a filter folder in the project.
-Place pragma warning disable statements in PCH files rather than in projects. This makes it easier when using Qt Creator.
-Move all resource files to the MSVC folder.
-Set all targets in QtCreator project to their lowercase names to be more *nix friendly. Set -l link statements to use these new lowercase names for ember and embercl.
-Rework projects to favor shadow builds.
-Remove the symlinks.sh file and all references to it. It was never needed. Instead, just specify multiple include and link paths in the .pro files.
-Change WIN32 to _WIN32.
-Fix a few code warnings.
-Fix crash when using Lanczos2 filter with color curves due to negative numbers. Fix by passing abs() of first argument to pow() in Renderer::GammaCorrection().
-Fix crash in hexes with SP. Rounding error caused out of bounds index.
-Draw selection circles around all selected xforms plus the current one.
--Bug fixes
-Add control key as a modifier to increase the amount a spinbox is changed when using right mouse drag to edit. Previously only observed shift key to decrease the value.
-Change the copy/paste selected xforms shortcuts to be Ctrl+X+C and Ctrl+X+V.
--Code changes
-Add function Fractorium::IsXformSelected() to determine if an xform has been selected with the checkboxes.
-Devices settings was empty on first run, so switching to OpenCL had no effect until the user manually selected a device in the options dialog. Fix by defaulting to device 0 if present.
-Split VariationList into .h/cpp files.
--Make VariationList.cpp the only place where the variations files are included from. This speeds up the build, but variations can no longer be directly instantiated.
--Variations are no longer exported.
-Add 4 new possible arguments to EmberGenome:
--allvars: Print the names of all supported variations.
--regvars: Print the names of all supported regular variations.
--prevars: Print the names of all supported pre variations.
--postvars: Print the names of all supported post variations.
-Add variations changes to the list of functionality that can be applied to all xforms using the Select tab.
-Allow for graphical affine adjustments to apply to multiple selected xforms.
-Slight optimization of the pie variation.
-Undo state is only saved when the render completes and the mouse buttons are released. This helps avoid intermediate steps for quickly completing renders while dragging.
-Add some keyboard shortcuts for toolbar and menu items.
-Make info tab tree always expanded.
--Bug fixes
-Make precalcs for all hypertile variations safer by using Zeps() for denominators.
-Changing the current xform with more than one selected would set all xform's color index value that of the current one.
-Use hard found palette path information for randoms as well.
-OpenCL build and assignment errors for Z value in epispiral variation.
-Unitialized local variables in hexaplay3D, crob, pRose3D.
--Code changes
-Change static member variables from m_ to s_.
-Get rid of excessive endl and replace with "\n".
-Remove old IMAGEGL2D define from before Nvidia supported OpenCL 1.2.
-Remove old CriticalSection code and use std::recursive_mutex.
-Make Affine2D Rotate() and RotateTrans() take radians instead of angles.
-More C++11 work.
-General cleanup.
-Allow locking of the scale at which affine circles are displayed.
-Allow user to toggle whether xform will be animated when generating sequences. Also show the animate value when loading.
--Code changes
-More conversion to C++11 style code.
-Add another value to the eXformUpdate enum called UPDATE_CURRENT_AND_SELECTED in anticipation of future work.
-Remove some old #defines.
-Allow for pausing the renderer in the main window. This makes is more efficient when entering many parameters, such as when following a tutorial.
-Add support for new variations: erf, gamma, jac_cn, jac_dn, jac_sn, logDB, pressure_wave, pRose3D, splits3D, w, waves2b, x, xerf, y, z.
-Inform user of the start and stop of file parsing in EmberAnimate because the files could potentially be very large.
-Move the follwing fields to a new table called Animation: Interpolation, Affine Interpolation, Temporal Samples, Temporal Filter Width, Temporal Filter Type.
-These currently have no effect on the interactive renderer and instead are used when running flames through EmberGenome to generate sequences, and then animating them in Fractorium or EmberAnimate.
-Add new parameter overrides for EmberRender and EmberAnimate which directly assign values to all flames being rendered, rather than scale:
--quality
--demin
--demax
--Bug fixes
-Left pad instead of right pad names of sequence outputs from EmberGenome.
-Unique file naming was broken for files which already had an underscore in them.
-Properly report that png is the default format of EmberRender and EmberAnimate output instead of erroneously claiming it was jpg.
-Make command line programs search these folders in this order for the palette file:
./
~/.fractorium
~/.config/fractorium
/usr/share/fractorium
/usr/local/share/fractorium
-Fix possible bad values in hexes.
-Better assignment of Z variables.
-Fix boarders due to use of poorly implemented rint() function from flam3. Use std::rint() now.
-wedge_sph was completely wrong due to having accidentally swapped the mapping of two parameters.
-Make juliascope juliascope_power parameter be of type REAL_NONZERO since it's used as a denominator.
-Make Z assignment compatible with the originals in:
-arch, bcircle, bCollide, bent, bent2, bisplit, blob, blur_linear, blur_square, bMod, boarders, boarders2, bSwirl, bTransform, butterfly, cardioid, cell, circleblur, circlize, circlize2, circus, collideoscope, cos, cosine, cosh, coth, cpow, cpow2, crescents, cropn, csc, csch, curl, curve, dc_gridout, deltaa, diamond, disc2, eclipse, eCollide, edisc, eJulia, elliptic, eMod, eMotion, ennepers, epispiral, ePush, eRotate, eScale, eSwirl, ex, exp, expo, exponential, fan, fdisc, fibonacci, fibonacci2, fisheye, flipcircle, flipy, flower, flux, funnel, glynnia, GlynnSim1, GlynnSim2, GlynnSim3, gridout, handkerchief, heart, hole, idisc, julia, julian2, juliaNab, kaleidoscope, lazyTravis, Lissajous, mask, MobiusN, mobius_strip, modulus, murl, murl2, npolar, ortho, oscilloscope, parabola, perspective, petal, phoenix_julia, pie (was also inconsistent between cpu and gpu), poincare, popcorn, popcorn2, power, pow_block, rational3, rays, rblur, rings, rippled, roundspher, sec, secant2, sigmoid, sin, sineblur, sinh, sinusgrid, sphericaln, spiralwing, spirograph, split, squarize, squirrel, squish, sschecks, starblur, stripes, stwin, super_shape, tan, tancos, tangent, tanh, TwinTrian, twoface, unpolar, waves, wavesn, wedge_julia, whorl, xheart, zblur, zscale.
--Code changes
-Generalize Variation::PrecalcHelper() and rename to PrePostPrecalcHelper().
--Do the same for the OpenCL version and rename it PrePostPrecalcOpenCLString().
-Rename Variation::m_AssignType to m_PrePostAssignType since it's only relevant to pre/post variations.
-Add the following modes to synth:
-MODE_SHIFTNSTRETCH 14
-MODE_SHIFTTANGENT 15
-MODE_XMIRROR 17
-MODE_XYMIRROR 18
-MODE_SPHERICAL2 19
-Clamp synth_mode, synth_*_type and synth_*_layer to valid values.
--Bug fixes
-synth was broken due to passing synth_mode to Interpolate, rather than synth_smooth.
-Fix bad include and link path in EmberAnimate project.
-Add post_smartcrop.
--Bug fixes
-Fix bug in crackle.
-Wrong point assignment in hexaplay3D, hexnix3D.
-Improper Z assignment in rblur.
-Fix inconsistency with original in circlecrop.
-Put EMBER_ROOT bakc to ./../../../ in default.pri. This is TBD.
--Code changes
-Convert all enums to class enum to be consistent with C++11 style.
-Convert some if/else statements in filter classes to case statements.
-Add overloaded stream operators to print various enums.
-Optimize crob, nBlur.
-Fix weird assignment statement in falloff3.
-Cleanup in VarFuncs::SimplexNoise3D().
-Replace fabs() with std::abs().
-General cleanup.
-Convert all enums to class enum to be consistent with C++11 style.
-Convert some if/else statements in filter classes to case statements.
-Add overloaded stream operators to print various enums.
-Convert all enums to class enum to be consistent with C++11 style.
-Convert some if/else statements in filter classes to case statements.
-Add overloaded stream operators to print various enums.
-Add new variations: crackle, dc_perlin.
-Make default palette interp mode be linear instead of step.
-Make summary tab the selected one in the Info tab.
-Allow for highlight power of up to 10. It was previously limited to 2.
--Bug fixes
-Direct color calculations were wrong.
-Flattening was not applied to final xform.
-Fix "pure virtual function call" error on shutdown.
--Code changes
-Allow for array precalc params in variations by adding a size member to the ParamWithName class.
-In IterOpenCLKernelCreator, memcpy precalc params instead of a direct assign since they can now be of variable length.
-Add new file VarFuncs to consolidate some functions that are common to multiple variations. This also contains texture data for crackle and dc_perlin.
-Place OpenCL versions of these functions in the FunctionMapper class in the EmberCL project.
-Add new Singleton class that uses CRTP, is thread safe, and deletes after the last reference goes away. This fixes the usual "delete after main()" problem with singletons that use the static local function variable pattern.
-Began saving files with AStyle autoformatter turned on. This will eventually touch all files as they are worked on.
-Add missing backslash to CUDA include and library paths for builds on Nvidia systems.
-Add missing gl.h include for Windows.
-Remove glew include paths from Fractorium, it's not used.
-Remove any Nvidia specific #defines and build targets, they are no longer needed with OpenCL 1.2.
-Fix bad paths on linux build.
-General cleanup.
