Detailed Description

template<class T>
class osg::TriangleFunctor< T >

Provides access to the triangles that compose an osg::Drawable. If the Drawable is not composed of triangles, the TriangleFunctor will convert the primitives to triangles whenever possible.

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

See also
PrimitiveFunctor for general usage hints.

template<class T >
virtual void osg::TriangleFunctor< T >::begin ( GLenum  mode)
inlinevirtual

Note: begin(..),vertex(..) & end() are convenience methods for adapting non vertex array primitives to vertex array based primitives. This is done to simplify the implementation of primitive functor subclasses - users only need override drawArray and drawElements.

Implements osg::PrimitiveFunctor.
