So an .obj is made up of vertices (v) and faces (f). Vertices have x, y and z coordinates. Faces are triangular, each face being defined by 3 vertices. For example:

v x y z
v -1 -1 -1
v -1 -1 1
v -1 1 -1
.........
f 1 2 3
f 5 3 2
f 7 1 8
..........

So in this case the first face is a triangle with extremeties at the first 3 vertices. The second face is defined by vertices 5, 3 and 2.....and so on. Is there a function in matlab which can plot this type of data?
