SoConvexDataCache

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.

SYNOPSIS

#include <Inventor/caches/SoConvexDataCache.h>

Inherits SoCache.

Public Types

enum Binding { NONE = 0, PER_FACE, PER_FACE_INDEXED, PER_VERTEX, PER_VERTEX_INDEXED }
The Binding enum is used to specify bindings.

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.
