The results should be like this:

This repo contains source code (training / inference) of 3D diffusion model, pretrained weights and gradio demo code of our 3D mesh generation project, you can find more visualizations on our project page and try our demo. If you have high-quality 3D data or some other ideas, we very much welcome any form of cooperation.

git clone https://github.com/wyysf-98/CraftsMan.git

conda create -n CraftsMan python=3.10 -y
conda activate CraftsMan
conda install cudatoolkit=11.8 -c pytorch -y
pip install torch==2.3.0 torchvision==0.18.0 
pip install -r docker/requirements.txt

We provide the training and the inference code here for future research. The latent set VAE model is heavily build on the same structure of Michelangelo. The latent set diffusion model is based on a DiT/Pixart-alpha and with 500M parameters.

Currently, We provide the models with single view image as condition with DiT. We will consider open source the further models according to the real situation. If you run the inference.py without specifying the model path, it will automatically download the model from the huggingface model hub.

Or you can download the model manually:

## you can just manually get the model using wget:
wegt https://huggingface.co/craftsman3d/craftsman-v1-5/blob/main/config.yaml
wegt https://huggingface.co/craftsman3d/craftsman-v1-5/blob/main/model.ckpt

## or you can git clone the repo:
git lfs install
git clone https://huggingface.co/craftsman3d/craftsman-v1-5

If you download the models using wget, you should manually put them under the ckpts/craftsman-v1-5 directory.

We provide gradio demos for easy usage.

python gradio_app.py --model_path ./ckpts/craftsman-v1-5

To generate 3D meshes from images folders via command line, simply run:

python inference.py --input eval_data --device 0 --model ./ckpts/craftsman-v1-5

For more configs, please refer to the inference.py.

We provide our training code to facilitate future research. And we provide a data sample in data. If you want to get the full data, please fill in the form

Due to the costs associated with data deployment. If you could help share our work on social media in any form, we would be grateful. As a token of our appreciation, you will receive download links to exclusive content stored on AWS S3, which can achieve download speeds of 20-100 MB/s.

For more training details and configs, please refer to the configs folder.

### training the shape-autoencoder
python launch.py --config ./configs/shape-autoencoder/michelangelo-l768-e64-ne8-nd16.yaml \
                 --train --gpu 0

### training the image-to-shape diffusion model
python launch.py --config .configs/image-to-shape-diffusion/clip-dino-rgb-pixart-lr2e4-ddim.yaml \
                 --train --gpu 0

We are diligently working on the release of our mesh refinement code. Your patience is appreciated as we put the final touches on this exciting development." 🔧🚀

You can also find the video of mesh refinement part in the video.

Q: Tips to get better results. 0. Due to limited resources, we will gradually expand the dataset and training scale, and therefore we will release more pre-trained models in the future.

1. Just like the 2D diffusion model, try different seeds, adjust the CFG scale or different scheduler. Good Luck.
2. We will provide a version that conditioned on the text prompt, so you can use some positive and negative prompts.
