Description

Project narrative

What it does

PLER compares a reference mesh and a distorted mesh by casting rays from a shared bounding sphere toward the center, measuring hit-length differences, and mapping the error into a log-scaled fidelity score. PLER 2.0 replaces uneven sampling with a Fibonacci (golden) spiral so coverage is stable across the surface.

Pipeline

Load & normalize → enclose in sphere → sample ray origins → intersect both meshes → aggregate MSE → optional topology / MOS regressor → report score. Open3D / Trimesh with research batch modes.
