MIRL 3D Artifact Analyzer

A browser-based tool for uploading, visualizing, and quantitatively analyzing 3D-scanned cultural artifacts. Developed for the MIRL (Material / Image Research Lab) at UC Santa Barbara to support structured-light scanning workflows and surface analysis research.

v2UC Santa BarbaraActive Development

Features

  • 3D mesh viewer with render modes & backgrounds
  • Mean, Gaussian & curvedness surface analysis
  • Interactive cross-section clipping plane
  • Side-by-side model comparison
  • Surface annotation with 3D pin markers
  • Custom JavaScript analysis scripts
  • PyVista backend integration for research-grade curvature
  • Export: curvature CSV, annotations JSON/CSV, screenshot

Tech Stack

  • Three.js r0.160 — 3D rendering
  • OBJLoader / MTLLoader — file support
  • CSS2DRenderer — annotation labels
  • Vanilla HTML/CSS/JS — no build step
  • Flask + PyVista + NumPy — optional backend

How to Use

Open in Chrome and drag an OBJ file onto the Viewer tab. Use the sidebar controls to explore surface analysis. Run the optional Python backend (mirl-backend.py) for higher-accuracy PyVista curvature.
