|
* raylib [models] example - loading gltf
|
|
*
|
|
* Example complexity rating: [★☆☆☆] 1/4
|
|
*
|
|
* LIMITATIONS:
|
|
* - Only supports 1 armature per file, and skips loading it if there are multiple armatures
|
|
* - Only supports linear interpolation (default method in Blender when checked
|
|
* "Always Sample Animations" when exporting a GLTF file)
|
|
* - Only supports translation/rotation/scale animation channel.path,
|
|
* weights not considered (i.e. morph targets)
|
|
*
|
|
* Example originally created with raylib 3.7, last time updated with raylib 4.2
|
|
*
|
|
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
|
|
* BSD-like license that allows static linking with closed source software
