The bulbous and heavily curved surfaces are all textured while the big pyramids have mostly pretty smooth surfaces, does even that just arise from the math or is there some kind of custom texturing going on?
(and if the answer is the former, I think I believe in God now)
The textures are really more a function of the lighting and coloring. (In this piece) So if I adjusted the colors, more texture could appear on the pyramids... same with adjusting the lights. That is not to say that textures are entirely produced by lights and colors of course. Tweaking the formula variables and changing formulas can also add texture... Thanks!
