I'm still preparing the post on grass blades. Part of the slowness is because I'm trying to go through each step incrementally, and show screenshots of the improvement. Because this means commenting out and tweaking parts of the grass code, I've ended up rewriting it a few times. The latest rewrite made the code simpler and saved some math, but it introduced an interesting bug. See if you can spot what's wrong:
If you guessed "those weird streaks shouldn't be there", then consider yourself a programmer, because they should almost definitely probably not be there.
Although they are pretty dramatically placed...
And they look kind of exciting...
I got too close. I guess this is my life now.
