Filter Objaverse Data

Filter Zero-1-to-3 rendered views (empty images) and save object ids:

python objaverse_filter.py --path /data/objaverse/views_release

There are 7983/798759 invalid object ids stored in invalid_ids.npy and 8607/798759 empty folders stored in empty_ids.npy. The all_invalid.npy stores 8607 invalid ids. We finally use 790152 objects from Objaverse Dataset. Zero-1-to-3's valid_paths.json contains 772870 ids.

Render GSO Data

We borrowed Zero-1-to-3's blender rendering scripts, set the GSO path and run:

python render_all_mvs.py

Coordinate System

Objaverse rendering: blender + T_cw Dust3r: opencv + T_wc NeRF: blender + T_wc

Dust3r -> Objaverse: inv(pose), pose[1:3, :] *= -1
