public class TriangleMesh
extends java.lang.Object

Representation of a single triangle mesh.

A triangle mesh consists of vertices, face sets connecting the vertices, and a single set of 2D texture coordinates (multitexture not supported by the .3ds format). Tangent and binormals are calculated on the fly from the provided information. The file definition of this chunk is:

 TRIANGULAR MESH 0x4100
     VERTICES LIST 0x4110
     FACES DESCRIPTION 0x4120
         FACES MATERIAL 0x4130
     MAPPING COORDINATES LIST 0x4140
     SMOOTHING GROUP LIST 0x4150
     LOCAL COORDINATES SYSTEM 0x4160
