MD3 (a la Quake 3) model loader for Go. This covers MD3 support as is used in Quake 3. It includes the md3 package for reading MD3 data and the go-md3 commandline tool for briefly inspecting MD3 files and converting them to OBJ files.

The go-md3 tool has three modes and a few options that affect only specific modes. The modes can be specified via -mode=[name] (or -mode name). The default mode is spec.

• spec

  Has no additional options. Displays a summary of the contents of any provided MD3 files, including surfaces, skins, frame counts, tag names, and so on.

• convert

  Converts provided MD3 files to OBJ files. Each frame is written as a separate OBJ file, named as such: <basename>+<frameNumber>.obj. Takes a few options:

  • -flipUVs=[true|false] — if true, the V texture coordinates will be flipped by writing them out as (1.0 - V). This is helpful if you work in a system that doesn't play nice with OpenGL's texture coordinate space. Defaults to true.

  • -swapYZ=[true|false] — if true, the Y and Z axes are swapped for vertices and normals. Defaults to true.

  • -o=path/to/output — sets the output directory for OBJ files. Defaults to the current directory (.).

• view

  Currently unimplemented and will result in a panic. Intended for viewing MD3 files with a given set of textures -- won't include a proper emulation of the Quake 3 shader system and such.
