Stripe reads .obj file and constructs a .objf file.  A complete description of the .obj format by Wavefront can be found at avalon.viewpoint.com or cica.indiana.edu.   This page will discuss the format of the .objf file whose format is very similar to the .obj file format.

File Structure

Vertex data
• geometric vertices (v)
• texture vertices (vt)
• vertex normals (vn)

** Vertex, textures, and normal list are all ordered sequentially starting with 1
 
Elements
• triangle strip (t)
• triangle strip continuation (q)
