Detailed Description

Basic class to load geometry from OpenSceneGraph node

Idea : This class contains the basic loading routines. Descendant classes can create their descendant versions of VertexBase and FaceBase classes but in that case it is IMPORTANT to also override methods that take care of allocation and returns the correct size of the used structure! You have to also call destroyGeometry() in your destructor (of the GeometryLoaderBase descendant).

Constructor & Destructor Documentation

SPACEPARTITIONING_IMP_EXP APSpacePartitioning::GeometryLoaderBase::GeometryLoaderBase ( )

SPACEPARTITIONING_IMP_EXP APSpacePartitioning::GeometryLoaderBase::~GeometryLoaderBase ( )

Don't forget to call destroyGeometry() in your destructor.
