LucidDreamer: Domain-free Generation of 3D Gaussian Splatting Scenes

*Jaeyoung Chung, *Suyoung Lee, Hyeongjin Nam, Jaerin Lee, Kyoung Mu Lee

We offer several ways to interact with LucidDreamer:

1. A demo is available on ironjr/LucidDreamer HuggingFace Space (including custom SD ckpt) and ironjr/LucidDreamer-mini HuggingFace Space (minimal features / try at here in case of the former is down) (We appreciate all the HF / Gradio team for their support).

2. Another demo is available on a Colab, implemented by @camenduru (We greatly thank @camenduru for the contribution).
3. You can use the gradio demo locally by running CUDA_VISIBLE_DEVICES=0 python app.py (full feature including huggingface model download, requires ~15GB) or CUDA_VISIBLE_DEVICES=0 python app_mini.py (minimum viable demo, uses only SD1.5).
4. You can also run this with command line interface as described below.

• Linux: Ubuntu>=18.04.
• CUDA>=11.4 (higher version is OK).
• Python==3.9 (cannot use 3.10 due to open3d compatibility)

conda create -n lucid python=3.9
conda activate lucid
pip install peft diffusers scipy numpy imageio[ffmpeg] opencv-python Pillow open3d torchvision gradio
pip install torch==2.0.1 timm==0.6.7 # ZoeDepth
pip install plyfile==0.8.1 # Gaussian splatting

cd submodules/depth-diff-gaussian-rasterization-min
# sudo apt-get install libglm-dev # may be required for the compilation.
python setup.py install
cd ../simple-knn
python setup.py install
cd ../..

# Default Example
python run.py

To run with your own inputs and prompts, attach following arguments after run.py.

• -img : path of input image.
• -t : text prompt. Can be either path to txt file or the text itself.
• -nt : negative text prompt. Can be either path to txt file or the text itself.
• -cg : camera extrinsic path for generating scenes. Can be one of "Rotate_360", "LookAround", or "LookDown".
• -cr : camera extrinsic path for rendering videos. Can be one of "Back_and_forth", "LLFF", or "Headbanging".
• --seed : manual seed for Stable Diffusion inpainting.
• --diff_steps : number of denoising steps for Stable Diffusion inpainting. Default is 50.
• -s : path to save results.

There are multiple available viewers / editors for Gaussian splatting .ply files.

1. @playcanvas's Super-Splat project (Live demo). This is the viewer we have used for our debugging along with MeshLab.

2. @antimatter15's WebGL viewer for Gaussian splatting (Live demo).

3. @splinetool's web-based viewer for Gaussian splatting. This is the version we have used in our project page's demo.
