Open source C++ skeletal animation library and toolset for runtime character animation playback with a data-oriented design.
ozz-animation is an open-source C++ library and toolset for 3D skeletal animation, providing runtime character animation playback functionalities such as loading, sampling, and blending. It solves the problem of implementing efficient, portable animation systems in real-time applications like games and simulations, with a focus on performance and memory constraints.
Game developers, graphics programmers, and engineers working on real-time 3D applications who need a lightweight, high-performance skeletal animation solution that is independent of specific rendering pipelines or game engines.
Developers choose ozz-animation for its data-oriented design, cross-platform portability, and agnostic approach to rendering and engines, offering optimized performance without locking into proprietary ecosystems.

The library's data-oriented design, emphasized in the README, optimizes for memory and performance constraints, making it ideal for real-time applications with strict requirements.
Tested on WebAssembly, Linux, macOS, and Windows for x86, x86-64, and ARM architectures, with runtime code depending only on C++17 and standard libraries, ensuring wide compatibility.
Its low-level implementation is independent of specific rendering pipelines or game engines, providing flexibility for integration into custom or existing systems without vendor lock-in.
Includes a toolchain to convert from major DCC formats like glTF, FBX, and Collada to optimized runtime structures, as noted in the README, streamlining asset pipeline integration.
As a renderer-agnostic library, it lacks skinning or rendering implementations, forcing developers to handle these aspects manually, which can increase development complexity and time.
Focused on low-level playback, it omits features like inverse kinematics or physics integration, requiring additional work for advanced animation systems beyond basic sampling and blending.
Being engine-agnostic means no out-of-the-box integration with popular engines, necessitating custom coding and deep C++ expertise to incorporate it into projects, as highlighted by its low-level approach.
