ply_io, a MATLAB code which reads or writes data describing a polygonal mesh in a PLY file.
A PLY file contains a sophisticated data structure describing a polygonal surface. A triangulated mesh is a very simply case of such a surface; a PLY file can also describe a mesh surface involving higher order polygons, and it can contain auxilliary information about normal vectors and so on.
A TRI_MESH or triangulated mesh surface, is described by a pair of arrays:

ply_io is available in a C version and a MATLAB version,
bezier_surface_display, a MATLAB code which reads two files defining a Bezier surface and displays it.
fem_basis_t3_display, a MATLAB code which displays a basis function associated with a linear triangle ("T3") mesh.
fem_basis_t6_display, a MATLAB code which reads a quadratic triangle mesh and displays any associated basis function.
obj_to_ply, a C code which converts a Wavefront OBJ file to PLY format.
plato_ply, a C code which creates a Platonic solid and writes it to an ASCII PLY file, by Greg Turk.
ply, a data directory which contains a description and examples of PLY files.
