Official implementation of ProlificDreamer: High-Fidelity and Diverse Text-to-3D Generation with Variational Score Distillation, published in NeurIPS 2023 (Spotlight).
The codebase is built on stable-dreamfusion. For installation,
pip install -r requirements.txt
ProlificDreamer includes 3 stages for high-fidelity text-to-3d generation.
# --------- Stage 1 (NeRF, VSD guidance) --------- #
# This costs approximately 27GB GPU memory, with rendering resolution of 512x512
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 25000 --lambda_entropy 10 --scale 7.5 --n_particles 1 --h 512 --w 512 --workspace exp-nerf-stage1/
# If you find the result is foggy, you can increase the --lambda_entropy. For example
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 25000 --lambda_entropy 100 --scale 7.5 --n_particles 1 --h 512 --w 512 --workspace exp-nerf-stage1/
# Generate with multiple particles. Notice that generating with multiple particles is only supported in Stage 1.
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 100000 --lambda_entropy 10 --scale 7.5 --n_particles 4 --h 512 --w 512 --t5_iters 20000 --workspace exp-nerf-stage1/
# --------- Stage 2 (Geometry Refinement) --------- #
# This costs <20GB GPU memory
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 15000 --scale 100 --dmtet --mesh_idx 0 --init_ckpt /path/to/stage1/ckpt --normal True --sds True --density_thresh 0.1 --lambda_normal 5000 --workspace exp-dmtet-stage2/
# If the results are with maney floaters, you can increase --density_thresh. Notice that the value of --density_thresh must be consistent in stage2 and stage3.
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 15000 --scale 100 --dmtet --mesh_idx 0 --init_ckpt /path/to/stage1/ckpt --normal True --sds True --density_thresh 0.4 --lambda_normal 5000 --workspace exp-dmtet-stage2/
# --------- Stage 3 (Texturing, VSD guidance) --------- #
# texturing with 512x512 rasterization
CUDA_VISIBLE_DEVICES=0 python main.py --text "A pineapple." --iters 30000 --scale 7.5 --dmtet --mesh_idx 0 --init_ckpt /path/to/stage2/ckpt --density_thresh 0.1 --finetune True --workspace exp-dmtet-stage3/
We also provide a script that can automatically run these 3 stages.
bash run.sh gpu_id text_prompt
For example,
bash run.sh 0 "A pineapple."
Limitations: (1) Our work ultilizes the original Stable Diffusion without any 3D data, thus the multi-face Janus problem is prevalent in the results. Ultilizing text-to-image diffusion which has been finetuned on multi-view images will alleviate this problem. (2) If the results are not satisfactory, try different seeds. This is helpful if the results have a good quality but suffer from the multi-face Janus problem.
- Release our code.
- Combine MVDream with VSD to alleviate the multi-face problem.
- ProlificDreamer is also integrated in Threestudio library ❤️.
