Overview
What this challenge is about.
Implement quadric-error-metric (QEM) mesh simplification with UV-attribute preservation: per-vertex 4x4 error quadrics that include a position term and a UV-distortion term, edge-collapse priority queue, boundary preservation. Run on 10 representative scans (provided as .obj, ranging 8M-22M triangles). Validate by side-by-side render comparison at 3 viewing distances. Wrap in a CLI tool with --target-triangles flag. Deliver source, the 10 simplified .obj outputs, render-comparison report, and a 6-page methodology document.
The Brief
What you'll do, and what you'll demonstrate.
Build a UV-preserving QEM mesh simplification pipeline that reduces 14M-triangle scans to under 1.5M without visible loss on 10 representative inputs.
Earning criteria — what you'll demonstrate
- Implement quadric-error-metric mesh simplification end-to-end
- Preserve UV attributes through edge collapses without seam tearing
- Validate geometry-processing pipelines with objective visual comparison
- Build a production-style CLI tool for a real ingest pipeline
