Support shadowing #3

Closed ianmackenzie closed 5 years ago

Either using traditional shadow maps or perhaps something clever/specialized like sets of analytical occluders (spheres, boxes etc.).

One cool approach would be to dynamically generate GLSL code for a given set of occluders; this could include hardcoded R-tree-like culling logic to quickly determine which occluders may affect a given light/ray.

Looks like you can close this.

Right you are! =) Would be cool to investigate shadow maps in the future but that will require changes to elm-explorations/webgl.
