Abstract
In various embodiments, an ray-marched-tangent space shader is provided which uses adaptive, curved ray marching of an implicit weave/thread procedural texture to create the appearance of individual cloth yarns complete with sub-fibers which separate rather than stretch over the surface. The volumetric surface shader shades cloth by performing adaptive curved ray marching of an implicit tangent space distance field.
