NAME
       ctmconv - file format converter for 3D models

SYNOPSIS
       ctmconv infile outfile [options]

DESCRIPTION
       ctmconv	is  a 3D file converter	that can convert 3D model files	to and
       from several different formats.

       The file	infile is loaded, and then saved as outfile in the target file
       format.

       The input and output file formats are determined	from the file endings.

OPTIONS
       The following options are available:

       --scale arg     Scale the mesh by a scalar factor.

       --upaxis	arg    Set up axis (X, Y, Z, -X, -Y, -Z). If !=	 Z,  the  mesh
		       will be flipped.

       --flip	       Flip triangle orientation.

       --calc-normals  If the source file does not contain any normals,	calcu-
		       late them.

       --no-normals    Do not export normals.

       --no-texcoords  Do not export texture coordinates.

       --no-colors     Do not export vertex colors.

       --comment arg   Set  the	 file  comment	(default is to use the comment
		       from the	input file, if any).

       --texfile arg   Set the texture file name  reference  for  the  texture
		       (default	is to use the texture file name	reference from
		       the input file, if any).

       When  exporting	an OpenCTM file, the following options are also	avail-
       able:

       --method	arg    Select compression method (RAW, MG1, MG2).

       --level arg     Set the compression level (0 - 9).

       --vprec arg     Set vertex precision (only for MG2).

       --vprecrel arg  Set vertex precision, relative method (only for MG2).

       --nprec arg     Set normal precision (only for MG2).

       --tprec arg     Set texture map precision (only for MG2).

       --cprec arg     Set color precision (only for MG2).

FILE FORMATS
       The following 3D	model file  formats  are  supported:  OpenCTM  (.ctm),
       Stanford	 triangle  format  (.ply),  Stereolitography (.stl), 3D	Studio
       (.3ds), COLLADA 1.4/1.5 (.dae), Wavefront geometry file (.obj),	Light-
       Wave  object (.lwo), Geomview object file format	(.off),	VRML 2.0 - ex-
       port only (.wrl).

AVAILABILITY
       ctmconv is designed to be portable, and is available for	 several  dif-
       ferent  systems,	 including  (but  not  limited	to): Windows, Mac OS X
       (10.3+),	Linux and OpenSolaris.
