Atlas Trace
Converts a 2D atlas image into a traced polygonal outline mesh whose silhouette follows the alpha rather than sitting on a rectangular quad.
Part of the experimental atlas pipeline. The overall shape is settled but individual parameters may move. Detailed parameter prose is still being filled in.
Atlas Trace is the trace step in the atlas pipeline. It takes an atlas image (with its alpha channel), or the lifted and embossed card, and walks the boundary to produce a polygonal outline mesh whose perimeter matches the alpha shape and whose interior is meshed to a target edge length. Two trace methods are available, selected by the Trace Method parameter.
