Shadow Experiments

Recommended Posts

This is my experiment in progress, analytical shadows

The idea behind it is upload scene geometry for fragment shader to analyze it for shadow volumes

It's terribly slow. My 1650s can only do 200 triangles in 4K

It's also not clear how to soften it properly. I'm doing pixel noise but adding an average loop is a sure way to slow things down even more. Screen space average?

The idea is the light has a non-zero size. If split by a surface, its halves are shining both ways

But yeah, with closed 3d shapes this should not happen

Here is a stochastic approach for shadow maps for comparison:
