Latest Substance Designer experiments. Some matrix math and vector work.

I am practicing working with vectors and matrices.

Using the second moment matrix to get the flow field from an rgb image

Procedurally generation of a hemisphere + normals + uvs

projection of 2d equirectangular hdri maps into 3d spherical, then projecting them back onto the sphere surface

using the Jacobian matrix to reduce distortions in uv maps

plotting L-norms

a simple star field shader
