Archives
- ZIP, 7Z, RAR and TAR/.tar.gz uploads are indexed in the background into
archive_entries (7-Zip compiled to WASM in a worker thread; node-tar for
tar). macOS/Windows clutter and paths that could escape the extraction
folder are skipped.
- Models inside archives are extracted once per archive to hash and
geometry-fingerprint them, so duplicates are found inside packs too.
Pictures, PDFs and readmes are listed but never matched.
- New routes list an archive's entries and serve/convert a single entry,
extracted on first use and cached under extracted/.
Viewer
- Model detail lists what's inside each archive with view/download links;
opening an entry adds a viewer tab.
- New 3D formats: FBX (with sibling textures), OBJ with its MTL and
textures, STEP/STP via occt-import-js, and Rhino 3DM via rhino3dm — the
WASM readers are served from node_modules, loaded on first use.
- Pictures, PDFs and text files (jpg/png/gif/webp/bmp/svg, pdf, txt/md)
can be uploaded and preview in the viewer; a model without an embedded
3MF preview uses its first picture as the card thumbnail.
- Inline file responses send nosniff, and SVGs are sandboxed.
- GLB conversions write to a temp file and rename, so a half-written
preview is never served; a later tab can't be overdrawn by a slow load.
- Better 3MF card image: the project thumbnail or plate 1 render, not a
slicer pick map.
