# SurfaceLab

SurfaceLab is a free web-based computational geometry platform for surface structure mesh generation. We help architects and structural engineers design and fabricate complex surface structures.

## What We Offer

- **Sphere Mesh Generator**: Free online tool for generating uniform geodesic sphere wireframe meshes from icosahedron subdivision
  - Real-time 3D preview (Three.js, runs in browser)
  - Quality evaluation metrics (CV, degree distribution, edge length statistics)
  - CAD-compatible DXF R2010 export
  - Adjustable parameters: diameter, target edge length, cut ratio
  - URL: https://surfacelab.tech/tool/sphere

- **REST API**: Machine-accessible endpoints for programmatic mesh generation
  - `POST /api/sphere/generate` — generate mesh JSON data
  - `POST /api/sphere/export-dxf` — generate and download DXF file
  - Both accept JSON: `{"diameter": 10.0, "target_length": 1.5, "cut_ratio": 1.0}`

## Who We Serve

- Architects designing complex surface structures (domes, shells, grid frames)
- Structural engineers needing mesh generation for analysis
- BIPV/BAPV (Building-Integrated Photovoltaics) designers
- Computational geometry researchers and students

## Technology Stack

- Backend: Python (Flask + Gunicorn), NumPy, ezdxf, geomdl (NURBS)
- Frontend: HTML/CSS/JS, Three.js for 3D visualization
- Deployment: Alibaba Cloud, Nginx reverse proxy, Let's Encrypt SSL

## Upcoming Features

- NURBS surface mesh generator (Y-Mesh algorithm)
- Parametric surfaces (cylinder, cone, paraboloid, hyperboloid)
- OpenSees structural analysis integration
- BIPV panel layout optimization
