Detailed DescriptionThe SoConvexDataCache class is used to cache convexified polygons​. SoConvexDataCache is used to speed up rendering of concave polygons by tessellating all polygons into triangles and storing the newly generated primitives in an internal cache​. This class is not part of the original SGI Open Inventor v2​.1 API, but is a Coin extension​.
