Three.js viewer supporting glb/gltf/obj/fbx/dae/ifc/ply via both server (SSR) and drag&drop (CSR) paths. - Streaming OBJ parser (src/viewer/objStream.ts) for files past the V8 max string length (>~1GB text) that OBJLoader can't handle; indexed geometry, per-vertex color from MTL Kd, float64 recenter baked in. - In-viewer float64 recenter (objRecenter.ts) for huge CAD/survey coordinates (~1e8) so float32 vertex buffers keep precision (no cracked faces). - Z-up right-handed world; Y-up formats rotated on load. - OBJ+MTL+texture drag&drop (LoadingManager URL-modifier maps dropped images). - OrbitControls ground-plane panning (road/rail alignment workflow). - UI: Zoom Fit, perspective/orthographic toggle, feature-edge outline. - DoubleSide for CAD OBJ; PLY mesh + point-cloud support.

description: Bootstrap the hmwebviewer project from the architecture spec (Phase 0). Run once when PLAN.md is not started.
|
|
---
|
|
|
|
Read `CLAUDE.md`, `PLAN.md`, `3d_viewer_architecture_spec.pdf` (extract via `pdftotext -layout`), then execute Phase 0 of PLAN.md:
|
|
|
|
1. Scaffold Vite + TypeScript project. Install `three` + `@types/three`.
|
|
2. Place Draco + KTX2 decoder assets under `public/draco` and `public/basis` (or wire CDN fallback). Pin to the installed three.js version.
|
|
3. Create a minimal `src/viewer/ThreeDViewer.ts` with a WebGLRenderer scene (camera, lights, resize loop) rendering a test cube.
|
|
|
|
Verify each step with real output: `npm run dev` serves, `npm run build` exits 0, console clean. Update PLAN.md (P0-* → done) and append to PROGRESS.md.

Arguments: $ARGUMENTS (optional override, e.g. package manager `pnpm`/`npm`).
