In this work we develop 3D Paintbrush, a technique for automatically texturing local semantic regions on meshes via text descriptions. Our method is designed to operate directly on meshes, producing texture maps which seamlessly integrate into standard graphics pipelines. We opt to simultaneously produce a localization map (to specify the edit region) and a texture map which conforms to it. This synergistic approach improves the quality of both the localization and the stylization. To enhance the details and resolution of the textured area, we leverage multiple stages of a cascaded diffusion model to supervise our local editing technique with generative priors learned from images at different resolutions. Our technique, referred to as Cascaded Score Distillation (CSD), simultaneously distills scores at multiple resolutions in a cascaded fashion, enabling control over both the granularity and global understanding of the supervision. We demonstrate the effectiveness of 3D Paintbrush to locally texture a variety of shapes within different semantic regions.
CSD Demo Notebook
To see a demo of the Cascaded Score Distillation (CSD) loss, check out this notebook applying CSD to image generation and image editing. CSD enables us to supervise our optimization with multiple cascaded stages of the diffusion model instead of just the base stage used in standard SDS. We distill scores across multiple stages of a cascaded diffusion model simultaneously in order to leverage both the global awareness of the first stage and the higher level of detail contained in later stages.

From Scratch
To reproduce results from the paper from scratch, just pass a predefined demo config file. Results will be saved at results/[name-of-mesh]/[name-of-edit]
.
Spot:
python src/main.py --config_path demo/spot/gold_chain_necklace.yaml
python src/main.py --config_path demo/spot/heart-shaped_sunglasses.yaml
python src/main.py --config_path demo/spot/colorful_crochet_hat.yaml
Person:
python src/main.py --config_path demo/person/tie-dye_apron.yaml
python src/main.py --config_path demo/person/colorful_polo.yaml
python src/main.py --config_path demo/person/superman_chest_emblem.yaml
Lego Minifigure:
python src/main.py --config_path demo/lego_minifig/barcelona_jersey.yaml
python src/main.py --config_path demo/lego_minifig/blue_denim_overalls.yaml
python src/main.py --config_path demo/lego_minifig/red_bow_tie.yaml
Hand:
python src/main.py --config_path demo/hand/fancy_gold_watch.yaml
Run your own examples
To run your own examples you can create your own config files and pass those as done in the prior section. Additionally, you can instead pass values for any of the fields in src/configs/train_config
as command line arguments. For example, to run the hand example without passing a config file, you may call:
python src/main.py --log.exp_dir results/hand/fancy_gold_watch --mesh.path ./data/spot.obj --guidance.object_name "hand" --guidance.style "fancy gold" --guidance.edit "watch"
Memory Optimization
If you do not have access to a 48 GB GPU, you can...
- Enable CPU offloading by setting the flag
cpu_offload
toTrue
insrc/configs/guidance_config.py
. This will significanly reduce memory usage, but comes at the cost of speed. - Use a smaller batch size by changing the
batch_size
parameter either with the command line argument--optim.batch_size
or in a custom config file. While this reduces memory usage, it can affect the accuracy. - Sample a subset of surface points each iteration (set
sample_points
toTrue
and adjustmlp_batch_size
). While this reduces memory usage, it can affect the accuracy. - Turn off batched score distillation calls (set
batched_sd
toFalse
). This will reduce memory usage, but comes at the cost of speed.
