Remix #rainbow #flag with improved palette and #phong #shading with better shadows- - #pride #pbr

u/f8f82804

Correct shadows are implemented with the 0<α factor. To golf this in, I had to drop the diffuse reflection term and reuse constants. Palette improvements just took tweaking without extra characters.
u/f8f82804

Loop restructuring also give a very slight FPS improvement.

Needs more golfing to add an animated wave

Show more comments…
u/magna

~~(Y/3)%2 can be shortened to Y/3&1
u/magna

(X-Y)%4 can be shortened to X-Y&3
u/magna

Added some waves (not so nice): https://www.dwitter.net/d/2188
u/scottglz

I had figured out Y/3%2 before I saw your comment, but X-Y&3 eluded me. Thanks!
