Detailed Description

A class which holds vertices and connectivity information for a triangle mesh.

This is a general vertices structure but it is mostly useful for LOD generation since every vertex contains information which helps selecting the best vertices for collapsing.

Constructor & Destructor Documentation

csTriangleVerticesCost::csTriangleVerticesCost ( csTriangleMesh mesh,
csVector3 verts,
int  num_verts 
)

Build vertex table for a triangle mesh.

Parameters:
mesh is the triangle mesh from which to calculate connectivity information.
verts is an array of vertices that will be used to fill the cost vertex table.
num_verts is the size of that table.
