Any other resources on empirically derived rendering/animation methods? A lot of hobbyist gamedevs can think of tutorials where we "slap noise" on various things. While a good temporary use, there's an pedagogical gap between beginner and advanced methods. Another that comes to mind is vegetation animation. Like ocean waves, we often see animators throw a few octaves of sin/cos on plants to simulate wind, but because it doesn't spectrally match what we see in the real world, it looks off.
