|
|
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.
