uCO3D80

uCO3D80 is the fixed 80-class uCO3D derivative used by GAPrompt++. It contains only the segmented_point_cloud.ply files referenced by the paper experiments.

This derivative selects 80 categories, copies the corresponding point clouds, preserves the fixed GAPrompt++ train/test split, and adds classification metadata. Retain the attribution, source links, license link, and modification notice when using or redistributing the dataset. This derivative is not an official Meta or uCO3D split and does not imply upstream endorsement.

Loading

Use this directory as the dataset root. The GAPrompt++ loader resolves each relative file_path from the fixed split. Evaluation uses deterministic sampling based on EVAL_SEED + CRC32(model_id).

Integrity

dataset_info.json records counts and source metadata hashes. FILES_SHA256SUMS.txt validates every controlled file.
