UNSUPPORTED: m2off - convert a LiveGraphics3D 'm' file to OFF format

Usage

Usage: m2off [options] [input_file]

Convert files in 'm' format, used by LiveGraphics3D, to OFF format. If
input_file is not given the program reads from standard input.

Options
  -h,--help this help message (run 'off_util -H help' for general help)
  --version version information
  -x <elms> hide elements. The element string can include v, e and f
               to hide, respectively, vertices, edges and faces
  -l <lim>  minimum distance for unique vertex locations as negative exponent
               (default: 12 giving 1e-12)
  -b        use back face colors instead of front ones, if available
  -o <file> write output to file (default: write to standard output)

Scene Options
  -v        turn model to LiveGraphics3D viewpoint
  -C <file> dump color lights into OFF file

Examples

off_util snub_dodecahedron | off2m -t 0 -l > snub_dod.m

m2off snub_dod.m > snub_dod.off

m2off -C color.off snub_dod.m | off_color -f L -l color.off | antiview

Convert a vertex only .m file, and view it

m2off color_cylinder.m | antiview -v 0.14

m2off -b -v color_cube.m | antiview

Notes

If faces in the .m file are displayed using LiveGraphics3D lighting it is possible that they may not also have particular colours assigned to them. In this case the colour used in the OFF file will be inherited from another element. It is likely that this will not be what is wanted, in which case the faces can be recoloured using off_color.

Please, report any difficulties in converting .m files.
