Detailed Description

template<class T>
class osg::TemplatePrimitiveFunctor< T >

Provides access to the primitives that compose an osg::Drawable.

Notice that TemplatePrimitiveFunctor is a class template, and that it inherits from its template parameter T. This template parameter must implement operator()(const osg::Vec3 v1, const osg::Vec3 v2, const osg::Vec3 v3, bool treatVertexDataAsTemporary), operator()(const osg::Vec3 v1, const osg::Vec3 v2, bool treatVertexDataAsTemporary), operator()(const osg::Vec3 v1, const osg::Vec3 v2, const osg::Vec3 v3, bool treatVertexDataAsTemporary), and operator()(const osg::Vec3 v1, const osg::Vec3 v2, const osg::Vec3 v3, const osg::Vec3 v4, bool treatVertexDataAsTemporary) which will be called for the matching primitive when the functor is applied to a Drawable. Parameters v1, v2, v3, and v4 are the vertices of the primitive. The last parameter, treatVertexDataAsTemporary, indicates whether these vertices are coming from a "real" vertex array, or from a temporary vertex array, created by the TemplatePrimitiveFunctor from some other geometry representation.

See also: PrimitiveFunctor for general usage hints.
