Finally, someone got shaders running on the Vegas sphere! Next step: let’s make this happen in mixed reality so everyone can write shaders on a virtual version of the sphere 😃

I have no idea how this shader works, but reducing the iteration count in the second loop kinda looks nice too.

A new video of a wobbly cube that's rendered via ray-marching a discretized SDF. Hypnotic!
Distances are reconstructed via trilinear interpolation of cached values on a grid.
This is the equivalent of what was shown in my earlier 2D animations (see below!)
