Use open-source openctm for commonly used 3D format Interchange

1. SupportedImportThe 3D formats include:

Openctm (. CTM), Stanford triangle format (. ply), stereolitography (. STL), 3D Studio (. 3DS), Collada (. DAE ),

Wavefront geometry file (. OBJ), Lightwave object (. lwo), geomview object file format (. Off)

2. SupportedExportThe 3D formats include:

Openctm (. CTM), Stanford triangle format (. ply), stereolitography (. STL), 3D Studio (. 3DS), Collada (. DAE ),

Wavefront geometry file (. OBJ), Lightwave object (. lwo), geomview object file format (. Off), fig 2.0 (. WRL)

3.Texture mapsFormat: JPEG, PNG

4. Use the command line toolCtmconv.exeBatch Conversion

Example: ctmconv Infinite-Level_02.3ds Infinite-Level_02.obj

The detailed parameters are as follows:

Usage: ctmconv infile OUTFILE [Options]

Options:

Data manipulation (all formats)
-- 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 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.

Openctm output
-- Method Arg select compression method (raw, Mg1, Mg 2)
-- Level Arg set the compression level (0-9)

Openctm Mg 2 Method
-- Vprec Arg set vertex precision
-- Vprecrel Arg set vertex precision, relative Method
-- Nprec Arg set normal precision
-- Tprec Arg set texture map precision
-- Cprec Arg set color precision

Miscellaneous
-- 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 ).

Supported file formats:

Openctm (. CTM)
Stanford triangle format (. ply)
Stereolithography (. STL)
3D Studio (. 3DS)
Collada 1.4/1.5 (. DAE)
Wavefront geometry file (. OBJ)
Lightwave object (. lwo)
Geomview object file format (. Off)
Fig 2.0 (. WRL)-export only
