NAME


mgf2rad - convert Materials and Geometry Format file to RADIANCE description

SYNOPSIS


mgf2rad [ -m matfile ][ -e mult ][ -g dist ] [ input .. ]

DESCRIPTION


Mgf2rad converts one or more Materials and Geometry Format (MGF) files to a RADIANCE scene
description. By definition, all output dimensions are in meters. The material names and
properties for the surfaces will be those assigned in MGF. Any materials not defined in
MGF will result in an error during translation. Light sources are described inline as IES
luminaire files, and mgf2rad calls the program ies2rad(1) to translate these files. If an
IES file in turn contains an MGF description of the local fixture geometry, this may
result in a recursive call to mgf2rad, which is normal and should be transparent. The
only side-effect of this additional translation is the appearance of other RADIANCE scene
and data files produced automatically by ies2rad.

The -m option may be used to put all the translated materials into a separate RADIANCE
file. This is not always advisable, as any given material name may be reused at different
points in the MGF description, and writing them to a separate file loses the contextual
association between materials and surfaces. As long as unique material names are used
throughout the MGF description and material properties are not redefined, there will be no
problem. Note that this is the only way to get all the translated materials into a single
file, since no output is produced for unreferenced materials; i.e. translating just the
MGF materials does not work.

The -e option may be used to multiply all the emission values by the given mult factor.
The -g option may be used to establish a glow distance (in meters) for all emitting
surfaces. These two options are employed principally by ies2rad, and are not generally
useful to most users.

EXAMPLE


To translate two MGF files into one RADIANCE materials file and one geometry file:

mgf2rad -m materials.rad building1.mgf building2.mgf > building1+2.rad

To create an octree directly from two MGF files and one RADIANCE file:

oconv '\!mgf2rad materials.mgf scene.mgf' source.rad > scene.oct
