#include <Inventor/caches/SoConvexDataCache.h>
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.
