MGF is an ASCII-based 3D rendering format designed to model surface geometry
and materials for the purpose of visible-light simulation and rendering.  The
overall objective of this format is to provide a very simple yet fairly
complete modeling language that does not place unreasonable demands on the
applications programmer or the object library creator.

The materials are physically-based and rely on standard and well-accepted
definitions of color, reflectance and transmittance for good accuracy and
reproducibility. The geometry is based on boundary representation using
simple geometric primitives such as polygons, spheres and cones. The file
format itself is terse but human-readable ASCII text.  Translators are
available from 3D Studio and Radiance rendering formats, and to Inventor,
VRML and Radiance.  An ANSI-C standard parser is freely distributed, along
with many models and examples at the official web site.

The format specification is available bundled with an MGF file reader
and is distributed in the file mgflib0.7.tar.Z on the following sites:

The MGF software is currently in its second official release (version 1.1).
