Triax is a program that generates a basic ICQ shape model that is a triaxal shape, which works for spheres and oblate spheres also.
When you run triax, you need to provide the semimajor axes for a, b and c.
- a is half of the longest equatorial diameter
- b is half of equatorial diameter that is 90 degrees from a
- c is half of the polar diamter
You also provide a Q factor (8 is a good place to start) and the filename.

The output is an ICQ shape model at whatever Q level specified.
