Reduction of aliasing artifacts along discontinuity edges of a rendered
polygon mesh is achieved by overdrawing the edges as antialiased lines. The discontinuity
edges are oriented consistently and blended as they approach silhouettes in the
mesh to avoid popping at the edge, thereby achieving a temporal smoothness at the
silhouettes. This temporal smoothness is balanced with a competing desire to maintain
spatial sharpness by utilizing an asymmetric blending technique. To further improve
results, the discontinuity edges can be sorted by depth prior to overdrawing them.
These processes are effective at reducing the temporal artifact known as "crawling jaggies".
