Test3Dmodels2

代码说明：

  This file contains a set of 3D models with the following characteristics: ■p: nx3 array of 3D points ■t: ntx3 array of triangles id. First points flagged as 1. ■tnorm: ntx3 arrays normals of triangles with outward orientation. You can use this package to test your algorithms. Models can be dowloaded here. All models were created with the new MyRobustCrust. In the new version all triangles have the same orientation, this allows for nice graphics rendering.
