All Code and demo will be released in this week(still ongoing...) 🏗️ 🚧 🔨

• Release main code
• Release blender addon
• Detailed README and installation guide
• Release skeleton-aware component, WIP as we need to split the joints into groups manually.
• Release codes for application
• Release codes for evaluation

Prerequisite

git clone [email protected]:wyysf-98/GenMM.git

conda create -n GenMM python=3.8
conda activate GenMM
conda install -c pytorch pytorch=1.12.1 torchvision=0.13.1 cudatoolkit=11.3 && \
pip install -r docker/requirements.txt
pip install torch-scatter==2.1.1

Quick inference demo

For local quick inference demo using .bvh file, you can use

python run_random_generation.py -i './data/Malcolm/Gangnam-Style.bvh'

More configuration can be found in the run_random_generation.py. We use an Apple M1 and NVIDIA Tesla V100 with 32 GB RAM to generate each motion, which takes about ~0.2s and ~0.05s as mentioned in our paper.

Blender add-on

You can install and use the blender add-on with easy installation as our method is efficient and you do not need to install CUDA Toolkit. We test our code using blender 3.22.0, and will support 2.8.0 in the future.

Step 1: Find yout blender python path. Common paths are as follows

(Windows) 'C:\Program Files\Blender Foundation\Blender 3.2\3.2\python\bin'
(Linux) '/path/to/blender/blender-path/3.2/python/bin'
(Windows) '/Applications/Blender.app/Contents/Resources/3.2/python/bin'

Step 2: Install required packages. Open your shell(Linux) or powershell(Windows),

cd {your python path} && pip3 install -r docker/requirements.txt && pip3 install torch-scatter==2.1.0 -f https://data.pyg.org/whl/torch-1.12.0+${CUDA}.html

, where ${CUDA} should be replaced by either cpu, cu117, or cu118 depending on your PyTorch installation. On my MacOS with M1 cpu,

cd /Applications/Blender.app/Contents/Resources/3.2/python/bin && pip3 install -r docker/requirements_blender.txt && pip3 install torch-scatter==2.1.0 -f https://data.pyg.org/whl/torch-1.12.0+cpu.html

Step 3: Install add-on in blender. Blender Add-ons Official Tutorial. edit -> Preferences -> Add-ons -> Install -> Select the downloaded .zip file

Step 4: Have fun! Click the armature and you will find a GenMM tag.

(GPU support) If you have GPU and CUDA Toolskits installed, we automatically dectect the running device.

Feel free to submit an issue if you run into any issues during the installation :)

Acknowledgement

We thank @stefanonuvoli for the help for the discussion of implementation about Motion Reassembly part (we eventually manually merged the meshes of different characters). And @Radamés Ajna for the help of a better huggingface demo.
