OBJ Files
A 3D Object Format
OBJ is a data directory which
contains examples of OBJ files, a format for storing a description
of the surface of a 3D object, composed of triangles or higher degree
polygons.
OBJ File Characteristics:
-
ASCII (there is also a binary version, for which an "MOD"
extension is used in the file name);
-
Color;
-
3D;
-
No compression;

Related Data and Programs:
MESHLAB,
examples which
illustrate the use of the meshlab program,
an advanced mesh processing system for automatic or user-assisted
editing, cleaning, filtering, converting and rendering of large
unstructured 3D triangular meshes.
MTL,
a data directory which
describes a file format used by OBJ to set material types.
