mrpt::opengl::COctreePointRenderer< Derived >::TNode Struct Reference

Detailed Description

template<class Derived>
struct mrpt::opengl::COctreePointRenderer< Derived >::TNode

The structure for each octree spatial node.

Each node can either be a leaf of has 8 children nodes. Instead of pointers, children are referenced by their indices in m_octree_nodes
