NAME
SoConvexDataCache - The 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.

Detailed Description
The 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.
