[WIP] Toon shading #5

Closed Eeems closed 8 months ago

Eeems commented 4 years ago

@StuntHacks While I've figured out how to bind in my own shader (stolen shamelessly from https://github.com/devkitPro/3ds-examples/tree/master/graphics/gpu/toon_shading), I'm not quite sure how to get it all working.

I must admit that my PICA200 is limited to knowing that it exists and it seems to share some simulatities with assembler.

Yes, picasso (the tool used to assemble shaders for the PICA200) is an assembler, and the language used is pretty much assembly. Having experience with GLSL-shaders is definitely extremely helpful, though, since most concepts are the same. I suggest looking at this (albeit rather simple) manual for the language, as well as this detailed documentation of the complete instruction-set.

I personally found it very helpful to check out already finished PICA200 shaders and comparing them to GLSL shaders, to get a grasp of how to use the language. Sadly, there aren't any actual good tutorials on how to use it that I know of.
