List of Shape Capping Types
The following are the capping types supported:
CAPTYPE_MORPH
This type of cap only uses the existing vertices in the PolyShape to generate the cap. The capping code does the best job it can given this constraint however it is possible to wind up with long sliver-like faces on the cap. This is referred to as a morph cap because if you cap a shape using this method it does not generate any new vertices and you can then morph between shapes with the same number of vertices.
CAPTYPE_GRID
This type of cap generates new vertices in the interior of the shape in a grid pattern. This helps to break up the shape and helps reduce slivering. Grid capping will generate different number of vertices based on the shape and thus the shapes are not morphable.
