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.

<!-- Cube.dae - hand-authored minimal COLLADA 1.4.1 unit cube for hmwebviewer ColladaLoader testing.
|
|
Single <geometry> (8 verts, 12 triangles) in one <visual_scene>. Edge length 2 (range -1..1),
|
|
centered at origin. Works for Path A (SSR ?model=) and Path B (drag & drop). No network required. -->
