Abstract:
A better silhouette for a mesh can be rendered if we take
into account the stability of edges inside and outside the
current silhouette. Using the dot product between the
normal and the viewing direction we can measure this
stability. This gives us two types of edges: silhouette and
non-silhouette and an associated stability of each. We
apply this classification and stability measure to achieve
several different styles of rendering as well as temporal
frame coherence.
