# 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 image
* `scene_[scene_id]_[frame_id].npy` : The corresponding depth map
* `scene_[scene_id]_[frame_id]_cam.txt` : The camera parameters
