render_objaverse.py

Renders Objaverse assets to create original 2D images.

• Downloads assets via Objaverse API
• Renders single view with white background

Output: original_2d/{uid}.jpg

render_recon.py

Renders reconstructed 3D meshes for evaluation.

• Renders 4 canonical views (0°, 90°, 180°, 270°)
• Renders 4 tilted views for better coverage

Output: {original/edited}_3d/{uid}/views/, views_tilted/

# Render Objaverse assets
python3 render_mesh/render_objaverse.py <output_dir> <input_path> <objaverse_dir>

# Render reconstructed meshes
python3 render_mesh/render_recon.py <recon_dir>

Parameters:

• input_path: Path to JSON file containing UIDs to render (e.g., prompts.json)
