This script imports Raw Triangle File format files to Blender.
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, a line with 12 values will be
imported as a quad. This may be in conflict with some other
applications, which use a raw format, but this is how it was
implemented back in blender 2.42.
Usage:<br>
Execute this script from the "File->Import" menu and choose a Raw file to
open.
Notes:<br>
Generates the standard verts and faces lists, but without duplicate
verts. Only *exact* duplicates are removed, there is no way to specify a
tolerance.
