3D model dataset

A collection of 3D models for use with experimenting. Currently private since lacking artist attribution.

Pipeline

raw:

• GLTF files with a file called scene.gltf ISSUE: NVDiffmod needs OBJ files with 1 texture Fix by using Blender-> This is done by running the script in process_dataset.blend.

objs:

• High-Poly OBJ file called hp.obj ISSUE: Multiple texture files, need to combine them Fix by reparameterizing and raycasting->

This is done by calling python3 unify_texs.py

processed:

• High-Poly OBJ file called hp.obj

Then from the high-poly files can derive low-poly files using Alpha Wrapping, Simplygon, etc.

This can be done by calling python3 reduction.py with Simplygon installed, or by calling python3 alpha_wrap.py && post_alpha_wrap_retex.py with CGAL installed.

Each of those scripts usually shells out to another script with some parameters set.
