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

◆ Binding

The Binding enum is used to specify bindings.

Binding applies to normals, materials and texture coordinates.

Constructor & Destructor Documentation

◆ SoConvexDataCache()

SoConvexDataCache::SoConvexDataCache ( SoState *const  state)

Constructor with state being the current state.

◆ ~SoConvexDataCache()

SoConvexDataCache::~SoConvexDataCache ( )
virtual

Destructor.
