ply_to_obj

ply_to_obj, a C code which converts a PLY 3D graphics file to an OBJ file.

The program only extracts information about vertices, faces, and vertex normals.

The PLY format allows faces to have as many vertices as desired. The OBJ format assumes faces are triangular. This program tries to convert nontriangular PLY faces to triangular faces acceptable to the OBJ format.

Usage:

ply_to_obj [flags] < file.ply > file.obj

• file.ply is the PLY file to be read;
• file.obj is the OBJ file to be created;
