put some shaders in the library ? #4

Open craff opened 3 years ago

Maybe in could be a good idea to put some shaders in the library ?

Typically:

a shader for points and lines (from examples/curves)
a shader for illumination with ambient/diffuse/specular light with a table of light source, similar to OpenGL (from examples/flying_cube, but need adaptation to an array of light source)
a shadow map shader (from examples/testc, examples/testd, examples/spheres), that would add shadow to the previous shader.

That is probably a good idea, not everyone may want (or know how) to write shaders. However, I'm not sure if this is something we should do right now. Maybe we should first try to have a DSL for shaders using OCaml types (GADTs and whatever else we may need to get a reasonable subset), and then provide shaders implemented encoded using these types and compiled from them. A good test for that language would be to see if the examples of shaders you propose to integrate can be expressed.
