[account ↗] [repo ↗] DATA_RESEARCH ★ 8846 1141 ● maintained (last update 6 months ago)
reviewed by: deepseek/deepseek-v4-flash

This repository provides a comprehensive research codebase for AI-driven character animation, spanning multiple SIGGRAPH publications from 2017 to 2024. It includes deep learning model training scripts (TensorFlow for PFNN, MANN, NSM; PyTorch for GNN, PAE, Codebook Matching) and corresponding Unity integration for real-time inference and visualization. The codebase ingests motion capture data (BVH, FBX, TRC), processes it through a Unity-based data pipeline (MotionData, Frame, Modules), trains phase-functioned or mode-adaptive networks, and exports trained weights for runtime use. The repository is hybrid: primarily a research project with both data pipeline (motion capture processing, feature extraction) and application (Unity demos, IK, visualization tools) components. It is not a standalone library but a reference implementation for academic publications, making it valuable for researchers and developers working on character animation, deep learning for motion, and real-time animation systems.

The LLM identified 5 files worth highlighting for reuse:

A comprehensive Unity Gizmo-based drawing library for debugging and visualizing 3D shapes, skeletons, text, and primitives. It is self-contained, well-documented, and can be dropped into any Unity project for immediate debug rendering.

file: AI4Animation/SIGGRAPH_2022/Unity/Assets/Scripts/Tools/UltiDraw/UltiDraw.cs ↗ | tags: #debug-visualization #unity-extension

A generic kd-tree implementation for fast nearest-neighbor searches in Unity. It supports arbitrary dimensions and distance functions, making it reusable for any spatial query task in games or simulations.

file: AI4Animation/SIGGRAPH_2022/Unity/Assets/Scripts/Tools/KDTree/KDTree.cs ↗ | tags: #spatial-index #nearest-neighbor

A dual CPU/GPU voxelizer that converts mesh geometry into a voxel grid. It uses compute shaders for performance and provides collision detection capabilities. Can be extracted as a standalone tool for rigid body or environment voxelization.

The main training script for the Phase-Functioned Neural Network. It demonstrates a clean separation of data loading, model definition, training loop, and evaluation. While project-specific, its structure serves as a reference for motion synthesis training pipelines.

file: AI4Animation/SIGGRAPH_2017/TensorFlow/PFNN/main.py ↗ | tags: #training-pipeline #phase-functioned-neural-network

An Anaconda environment file that pins Python dependencies for the generative model. It is the only explicit environment definition in the repository and can be reused to set up a consistent Python environment for PyTorch-based animation research.

file: AI4Animation/SIGGRAPH_2020/DeepLearning/Models/GenerativeModel/environment.yml ↗ | tags: #dependency-management #reproducibility
