ozz-animation
open source c++ 3d skeletal animation library and toolset
ozz-animation provides runtime character animation playback functionalities (loading, sampling, blending...). It proposes a low-level renderer agnostic and game-engine agnostic implementation, focusing on performance and memory constraints with a data-oriented design.
ozz-animation comes with the toolchain to convert from major Digital Content Creation formats (gltf, Fbx, Collada, Obj, 3ds, dxf) to ozz optimized runtime structures. Offline libraries are also provided to implement the conversion from any other animation and skeleton format.

Documentation
Documentation and samples are available from ozz-animation website.
Supported platforms
ozz-animation is tested on WebAssembly, Linux, macOS and Windows, for x86, x86-64 and ARM architectures. The run-time code (ozz_base, ozz_animation, ozz_geometry) depends only on c++11, on the C and the C++ standard libraries, and has no OS specific code. Portability to any other platform shouldn't be an issue.
Samples, tools and tests depend on external libraries (glfw, tinygltf, Fbx SDK, jsoncpp, gtest, ...), which aren't need to ship with ozz-animation runtime.
