How can I create a 3d surface plot from a set of vertices and faces found in an .obj file?

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?

doc triplot, trisurf, trimesh and also patch.

I have triagulated data set (vertices and face ) ,how to plot into matlab surf.

Thanks
