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, calculate 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 available:

       --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), LightWave  object  (.lwo),  Geomview  object  file  format
       (.off), VRML 2.0 - export only (.wrl).

AVAILABILITY

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