lunar

Features

• Analysis — topology, curvature, distance fields, histograms, per-component stats

• Arrangements & booleans — booleans, multi-mesh arrangements, polygon soup arrangements and self-intersection resolution

• Remeshing — isotropic remesh, decimation, Laplacian and Taubin smoothing

• Isocontours & isobands — scalar field level sets with curve triangulation

• Alignment — ICP and OBB registration, frame alignment

• AI-controllable — full MCP server; every operator callable by AI agents

• Import / Export — STL and OBJ with drag-and-drop

All computation runs in trueform's WASM runtime — parallel, exact, and browser-native.

Getting Started

pnpm install
pnpm dev              # Vite dev server (no MCP)
pnpm dev:mcp          # build + wrangler dev (full MCP stack, port 8788)

Requires Node 20+ and pnpm. pnpm dev is fastest for UI work. pnpm dev:mcp runs the full Cloudflare Worker stack locally with MCP support.

AI Integration

Lunar exposes an MCP server. Connect any MCP-compatible AI assistant (Claude, etc.) to control the scene programmatically — create geometry, run operators, inspect results, take screenshots. See the MCP panel in the app for the connection URL.
