TIP-Editor: An Accurate 3D Editor Following Both Text-Prompts And Image-Prompts (SIGGRAPH 2024 & TOG)

Project page |Paper |Initial 3D-GS | Edited 3D-GS

Todo

  • Release training code of step 1,2,3
  • Release all editing samples reported in the paper

Dependencies

Install with pip:

    pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio===0.12.1+cu116
    pip install git+https://github.com/NVlabs/tiny-cuda-nn/#subdirectory=bindings/torch
    pip install diffusers==0.22.0.dev0
    pip install huggingface_hub==0.16.4
    pip install open3d==0.17.0 trimesh==3.22.5 pymeshlab
    
    # install gaussian rasterization
    git clone --recursive https://github.com/ashawkey/diff-gaussian-rasterization
    pip install ./diff-gaussian-rasterization
    
    # install simple-knn
    git clone https://github.com/camenduru/simple-knn.git
    pip install ./simple-knn

Training requirements

  • Stable Diffusion. We use diffusion prior from a pretrained 2D Stable Diffusion 2.0 model. To start with, you may need a huggingface token to access the model, or use huggingface-cli login command.

Data process

Run COLMAP to estimate camera parameters. Our COLMAP loaders expect the following dataset structure in the source path location:

<./data/filename>
|---images
|   |---<image 0>
|   |---<image 1>
|   |---...
|---sparse
    |---0
        |---cameras.bin
        |---images.bin
        |---points3D.bin

Extract sparse points

    python colmap_preprocess/extract_points.py ./data/filename/

Align the scene with coordinate system. Get Orient_R.npy.

We use meshlab to align the scene with coordinate system. Click Filters->Normals,Curvatures and Orientation->Matrix: Set from translation\rotation\scale. Make sure the Y-axis is vertical and upward to the ground, and the object is oriented in the same direction as the z-axis.

Training

We provided some intermediate results:

Download editing scene data in the paper from Data

Download Initial 3D-GS

Download Finetuned SD models from baidunetdisk, password 8888

How to set 3D bounding box?

Users can extract the colored points of the scene from the trained 3D-GS for visualization as following:

    python save_scene_points.py --pth_path  .../xx.pth

Then Users can add a cube to the sparse points scene through meshlab or blender, scale and drag it to the desired position, and save it in .ply format.

Start training

    bash run_doll_sunglasses1.sh

Testing

Download Edited 3D-GS and unzip in res file

   bash test.sh
