Quick Start

1. Clone threestudio with the support of ProlificDreamer:

git clone https://github.com/threestudio-project/threestudio.git

2. Follow the instructions here to configure running environments and commands here to start your first text-to-3D experiments.

3. Experiencing Janus problem? Our paper suggests simply specifying the argument system.guidance.guidance_scale_lora can potentially relieve Janus problem. For example,

python launch.py --config configs/prolificdreamer.yaml --train --gpu 0
system.prompt_processor.prompt=<your_prompt> system.guidance.guidance_scale_lora=0.5

Note: The value of this hyperparameter may vary in different scenarios.

Check our paper for theoretical arguments on this surprising finding.

Gaussian Example

To demonstrate the principle of our algorithm, we provide an example script in gaussian_example.py to visualize the training trajectory of matching two Gaussian distribution using various score distillation schemes.

To reproduce these results, you may try the following commands:

# SDS
python gaussian_example.py --method sds --save_video
# VSD
python gaussian_example.py --method vsd --save_video
# ESD (Ours)
python gaussian_example.py --method esd --lambda_coeff 1.0 --save_video

It is also recommended to play with --lambda_coeff to see how this hyperparameter affect the matching results.
