Read and Write Wavefront OBJ geometry and MTL files.

A Wavefront Geometry Object file is supported by many 3D programs, it looks like:
v 0.000000 2.000000 0.000000
v 0.000000 0.000000 0.000000
v 2.000000 0.000000 0.000000
v 2.000000 2.000000 0.000000
% Vertices Coordinates 4
f 1 2 3 4
% Faces 1

The function read_wobj allow Wavefront object files including material MTL files to be read into a Matlab structure.
The function write_wobj exports a Matlab structure to an OBJ file.

It doesn't matter if the object file contains splines or polygon based geometry, it reads and writes almost all .obj files.

See "help read_wobj" and "help write_wobj"
