Inheritance diagram for KFbxMesh:

Detailed Description

A mesh is a geometry made of polygons.

Functions to initialize, set and access vertices are provided in theKFbxGeometrybase class. A vertex is referred as a control point in theKFbxGeometrybase class. Though a control point is made of four elements, meshes only use the first tree to store the XYZ coordinates.

Since the mesh-related terminology of the FBX SDK differs a little from the standard, here are some definitions:

A control point is a XYZ coordinate, it is synonym of vertex.
A polygon vertex is an index to a control point, it is synonym of vertex index.
A polygon is a group of polygon vertex.
