AI4AnimationPy is a Python framework for AI-driven character animation using neural networks, providing motion capture processing, training and inference, and animation engineering. It ports the Unity-based AI4Animation project to Python with a game-engine-style ECS architecture, running on NumPy/PyTorch with optional Raylib rendering.

Use cases

• train neural network controllers for character locomotion
• process motion capture data in Python
• run AI character animation headless on a server
• import and convert BVH FBX GLB animation files
• visualize interactive biped and quadruped locomotion demos
• implement inverse kinematics for animated characters

When to choose

• you want AI4Animation capabilities without a Unity dependency
• you need a unified Python environment for animation data processing, training, and inference
• you are researching neural character animation or motion synthesis

When to avoid

• you need a permissively licensed library for commercial products (CC BY-NC 4.0 is non-commercial)
• you need a production game-engine animation runtime rather than a research framework
• you require Unity or another full game engine integration
