REVIEWED: Reorganized structures for a clearer distinction between "skeleton", "skin" and "skinning" data ADDED: New structures: `ModelSkeleton`, `ModelAnimPose` (alias `Transform*`) ADDED: Runtime data `currentPose` and `boneMatrices` to `Model` structure ADDED: Support animation frames-blending, for timing control ADDED: Support animations blending, between two animations REVIEWED: All models animation loading functions ADDED: `UpdateModelAnimationEx()` for two animations blending REMOVED: `UpdateModelAnimationBones*()`, simplified API REVIEWED: Shader attributes/uniforms names for animations, for consistency REVIEWED: Multiple tweaks on animations loading for consistency between formats ADDED: example: `models_animation_timing` ADDED: example: `models_animation_blending` REVIEWED: example: `models_animation_gpu_skinning` REVIEWED: example: `models_animation_blend_custom` REVIEWED: All animated models loading examples

* raylib [models] example - loading iqm
|
|
*
|
|
* Example complexity rating: [★★☆☆] 2/4
|
|
*
|
|
* Example originally created with raylib 2.5, last time updated with raylib 3.5
|
|
*
|
|
* Example contributed by Culacant (@culacant) and reviewed by Ramon Santamaria (@raysan5)
|
|
*
|
|
* NOTES: To export an IQM model from blender, make sure it is not posed, the vertices need
|
|
* to be in the same position as they would be in edit mode and the scale of the models is
|
|
* set to 0; scaling can be set from the export menu
|

* BSD-like license that allows static linking with closed source software
