Grant Sanderson	045e1f6b8a	Instead of tracking du and dv points on surface, track points off the surface in the normal direction ... This means that surface shading will not necessarily work well for arbitrary transformations of the surface. But the existing solution was flimsy anyway, and caused annoying issues with singularity points.	2025-01-17 11:47:10 -06:00
