This script exports a Mesh to a RAW triangle format file.
The raw triangle format is very simple; it has no verts or faces lists.
It's just a simple ascii text file with the vertices of each triangle
listed on each line. In addition, also quads can be exported as a line
of 12 values (this was the default before blender 2.5). Now default
settings will triangulate the mesh.
Usage:<br>
Execute this script from the "File->Export" menu. You can select
whether modifiers should be applied and if the mesh is triangulated.
