NLPACS::COrderedChain3f Class Reference

#include <chain.h>

Detailed Description

A list of ordered vertices, partially delimiting 2 different surfaces. In the vertex list, we consider the following order v1 < v2 iff v1.x < v2.x || v1.x == v2.x && v1.y < v2.y || v1.x == v2.x && v1.y == v2.y && v1.z < v2.z The vertices composing the chain are actual CVector (12 bytes per vertex.)
