## What it is
DeepMimic is a C++ simulation framework with a Python (SWIG/TensorFlow) wrapper that trains simulated humanoid characters to imitate motion-capture skills using deep reinforcement learning. It implements the DeepMimic and AMP (Adversarial Motion Priors) research methods for physics-based character animation.

## Use cases
- train a simulated humanoid to imitate mocap motion clips with reinforcement learning
- research physics-based character animation and motion imitation
- reproduce DeepMimic or AMP paper experiments
- build RL agents that perform locomotion, acrobatics, and martial arts skills in physics simulation
- study adversarial motion priors for stylized character control

## When to choose
- you need the original reference implementation of the DeepMimic or AMP papers
- you are studying or extending physics-based motion imitation research in C++

## When to avoid
- you want a maintained or easy-to-use implementation - the README says this codebase is deprecated in favor of MimicKit
- you need modern TensorFlow or a quick setup - it depends on old TensorFlow 1.x and manual C++ builds

## Facets
- artifact type: library
- maturity: abandoned
