SimpleProc Dataset
This is the official WebDataset hosting for the SimpleProc dataset. Please find the download instructions in the official repository https://github.com/princeton-vl/SimpleProc.
Dataset Structure
The dataset is hosted as flattened .tar shards (e.g., shard-000000.tar). Inside these shards, all files belonging to a specific frame share a unified prefix:
scene_[scene_id]_[frame_id].png: The rendered RGB imagescene_[scene_id]_[frame_id].npy: The corresponding depth mapscene_[scene_id]_[frame_id]_cam.txt: The camera parameters
