BVH_PrimitiveSet< T, N > Class Template Reference

Set of abstract geometric primitives organized with bounding volume hierarchy (BVH). Unlike an object set, this collection is designed for storing structural elements of a single object (such as triangles in the object triangulation). Because there may be a large number of such elements, the implementations of this interface should be sufficiently optimized. More...

Detailed Description

template<class T, int N>
class BVH_PrimitiveSet< T, N >

Set of abstract geometric primitives organized with bounding volume hierarchy (BVH). Unlike an object set, this collection is designed for storing structural elements of a single object (such as triangles in the object triangulation). Because there may be a large number of such elements, the implementations of this interface should be sufficiently optimized.
