So far, our `plot()` function has been fairly simple; map an input coordinate
|
||
|
|
to a specific pixel, and color in that pixel.
|
||
|
|
This works well for simple function systems (like Sierpinski's Gasket),
|
||
|
|
but more complex systems (like our reference parameters) produce grainy images.
|
||
|
|
|
||
|
|
Every time we "turn on" pixels that have already been enabled, we're wasting work.
|
||
|
|
Can we do something more intelligent with that information?

|
To start with, it's worth demonstrating how much work is actually "wasted."
|
||
|
|
We'll render the reference image again, but this time, counting the times
|
||
|
|
we tried to turn on a pixel.
