MotionGen: 3D Motion Generation Model 163

MotionGen, a physics-based 3D motion generation model launched by Xuanmiao (3D), integrates cutting-edge algorithms such as large models, physics simulation, and reinforcement learning through innovative approaches. Users simply need to input simple text commands to quickly generate realistic, fluid, and complex 3D motions.

MotionGen addresses the problems of low efficiency, high cost, and reliance on manual production or expensive motion capture equipment in traditional 3D motion design. At its core, MotionGen is built on a physics-based model that combines advanced technologies such as large models, physics simulation, imitation learning, reinforcement learning, Vector Quantized Variational Autoencoders (VQ-VAE), and Transformer models. This allows users to simply input text commands to quickly generate high-quality, complex, and naturally fluid 3D character motions.

Key Features of MotionGen:

• Accurate Text Understanding: Capable of deeply parsing complex commands and accurately generating motions that match the text descriptions, achieving seamless text-to-motion conversion.

• Motion Richness: Supports a wide range of motions, from basic actions such as walking and running to complex coordinated limb movements such as kicking and spinning.

• Realistic Physics Simulation: Ensures that generated motions comply with physical laws with natural transitions between movements, such as a character being able to brake autonomously after a sprint, enhancing the detail performance of motion generation and alignment with text commands.

• Style Diversity: Even for the same motion, stylistic variations can be generated based on different descriptions, adding uniqueness to the motions.

MotionGen Technical Implementation:

MotionGenGPT Algorithm: Integrates physics simulation with reinforcement learning, trained using motion capture data. It generates natural motions through imitation learning, while adopting VQ-VAE to extract motion features, combined with the Transformer model to achieve efficient text-to-motion conversion.

Two-Stage Framework: First learns representations of physically correct motions, then refines motion encodings through a dual-Transformer model, ensuring that motions both comply with physical laws and exhibit high levels of detail and naturalness.
