Currently libgdx has two loaders for 3D assets:
.obj (Wavefront) – ascii, suitable for static geometry
.md5 (Doom 3) – ascii, used for skinned geometry
Both of these are kind of slow to parse as they’re stored in text format. I’m interested in exploring alternatives and implementing them for libgdx. My first thought is .x (DirectX, binary or ascii) would be a nice one as it’s commonly used. If you have any suggestions please go post on the forum thread!
