Just published Deltahedron, a funny little 3D interactive app to organically create polyhedra made only from equilateral triangles.

Here's the app

Hey, sorry for bothering you but I seem to be missing something completely.

I have a cube texture for environment lighting and want to create its irradiance map, so I need to integrate over the hemisphere of the 3D direction of each of the cube texels. How do I get this direction???
It's kind of the inverse of this function;

textureSample(cubeTexture, cubeSampler, direction)

like, I'm making this up:
texelDirection(cubeTexture, texelIndex)

Or how else would I do this? 😆
