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.

   Public Types

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.

Member Enumeration Documentation

   enum SoConvexDataCache::Binding
       The Binding enum is used to specify bindings. Binding applies to normals, materials and
       texture coordinates.

Constructor & Destructor Documentation

   SoConvexDataCache::SoConvexDataCache (SoState *conststate)
       Constructor with state being the current state.

   SoConvexDataCache::~SoConvexDataCache () [virtual]
       Destructor.
