G-WAVE(1)

NAME
g-wave - Wavefront Translator (BRL-CAD to Wavefront)

SYNOPSIS
g-wave [-mviu] [-xX lvl] [-e error_file] [-D calculation_tolerance ] [-a abs_tol] [-r rel_tol] [-n norm_tol] [-o Wavefront_file] database.g object(s)

DESCRIPTION
g-wave converts the specified object(s) from a BRL-CAD database.g file to the Wavefront OBJ file format. The -x option specifies an RT debug flag and the -X option specifies an NMG debug flag. The -a , -r , and -n options specifiy tesselation tolerances. The -D option specifies a calculational distance tolerance (mm). Any two vertices that are less than this distance apart will be treated as the same vertex. The -u option specifies that vertex normals are desired. The -v option requests verbose output. The -i option requests the output file units to be inches (the default is mm). The -o option specifies the mame of the file to receive the output (stdout is the default). The -m option will result in 'usemtl' statements in the output file. These statements are fictional (they do not refer to any material database). The materials named provide information about the material codes assigned to the objects in the BRL-CAD database. The material names will be of the form 'aircode_los_material', where aircode is the code number for the air represented by that region, if it does represent air, otherwise this will be zero. The los is the Line Of Sight thickness (0-100) assigned to the region, and the material is the material code number assigned. The -e option specifies a file for receiving the error messages.

EXAMPLE
    $ g-wave -o sample.Wavefront sample.g sample_object

DIAGNOSTICS
Error messages are intended to be self-explanatory.
