     ObjToIv - convert a Wavefront .obj	file to	Open Inventor 2.0 format

SYNOPSIS    [Toc]    [Back]

     ObjToIv [-h] [-g] [-m] [-n]
	     [-v] [-q] <infile>	<outfile>

DESCRIPTION    [Toc]    [Back]

     ObjToIv converts 3D model files in	Wavefront .obj format (versions	3.0
     and 4.0) into Open	Inventor 2.0 files. The	program	converts ASCII files
     in	.obj format, .pv files are not handled.	NURB and cardinal surface,
     polygons, groups, textures	are converted into equivalent Open Inventor
     objects. For textures, convert the	bitmap texture image to	an SGI .rgb
     file.  Place it in	the same directory as the .obj file. Use the function
     fromrla to	convert	.rla files into	.rgb files.  For materials, either the
     materials (.mtl) file must	be referenced within the .obj file, or the
     WF_MTL_LIB	environment variable must be set to the	file that has defines
     the materials referenced in the .obj file.	 If no -g flag is given	the
     translator	will take all the entities in the .obj file and	group them
     under one Open Inventor separator node.  Copyright	(c) Abaco Systems,

   Command Line	Options
     Typically,	ObjToIv	expects	a Wavefront .obj file to be specified on the
     command line after	all command option switches. If	no .obj	file is
     specified on the command line, ObjToIv will read from standard input
     (stdin).  By default, ObjToIv writes the converted	data to	standard
     output (stdout) and messages to standard error (stderr).

     -h	       Prints a	program	usage message to standard error	(stderr).


     -g	       Separate	the contents of	the .obj file by groups.  The default
	       is to separate by groups	and materials.


     -m	       Separate	the contents of	the .obj file by materials.  The
	       default is to separate by groups	and materials.


     -n	       Perform no separation the contents of the .obj file. The
	       default is to separate by groups	and materials.


     -v	       Turn on verbose output.	Verbose	output is off by default.


     -q	       Turn on quiet mode.  Quiet mode is off by default.  When	in
	       quiet mode, no output is	written	to stderr, including the
	       copyright notice.
