Fast silhouette and crease edge synthesis with geometry shaders
Balázs Hajagos, László Szécsi, Balázs Csébfalvi · 2012
We describe a technique to generate the geometry of silhouette and crease strokes in geometry shaders. This allows for single-pass, small-overhead rendering of conventional meshes. We exploit classic triangle adjacency information, but also introduce crease difference vectors associated with vertices in order to identify crease edges.
