Data download available at Hugging Face, including 1,002,422 descriptive captions for 3D objects in Objaverse and a subset of Objaverse-XL, from our two works Cap3D and DiffuRank. We also include 1,002,422 point clouds and rendered images (with camera, depth, and MatAlpha information), corresponding to the objects with captions. 3D-caption pairs for ABO are listed here.
Our 3D captioning codes can be found in the captioning_pipeline folder, while the text-to-3D folder contains codes for evaluating and fine-tuning text-to-3D models. Some newer code (e.g., rendering) are included at DiffuRank.
Cap3D provides detailed descriptions of 3D objects by leveraging pretrained models in captioning, alignment, and LLM to consolidate multi-view information.
