* raylib [models] example - loading
|
||||
*
|
||||
* raylib supports multiple models file formats:
|
||||
* Example complexity rating: [★☆☆☆] 1/4
|
||||
*
|
||||
* - OBJ > Text file, must include vertex position-texcoords-normals information,
|
||||
* if files references some .mtl materials file, it will be loaded (or try to)
|
||||
* - GLTF > Modern text/binary file format, includes lot of information and it could
|
||||
* also reference external files, raylib will try loading mesh and materials data
|
||||
* - IQM > Binary file format including mesh vertex data but also animation data,
|
||||
* raylib can load .iqm animations.
|
||||
* NOTE: raylib supports multiple models file formats:
|
||||
*
|
||||
* This example has been created using raylib 2.6 (www.raylib.com)
|
||||
* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
|
||||
* - OBJ > Text file format. Must include vertex position-texcoords-normals information,
|
||||
* if .obj references some .mtl materials file, it will be tried to be loaded
|
||||
* - GLTF/GLB > Text/binary file formats. Includes lot of information and it could
|
||||
* also reference external files, mesh and materials data will be tried to be loaded
|
||||
* - IQM > Binary file format. Includes mesh vertex data but also animation data,
|
||||
* meshes and animation data can be loaded
|
||||
* - VOX > Binary file format. MagikaVoxel mesh format:
|
||||
* https://github.com/ephtracy/voxel-model/blob/master/MagicaVoxel-file-format-vox.txt
|
||||
* - M3D > Binary file format. Model 3D format:
