The 3D viewer

The viewer is where the digitized work submits to examination. It opens in an ordinary browser, and because the rendering happens in the cloud and only the image is streamed to your screen, even the heaviest full-resolution model opens at once on any device: the study room workstation, an iPad in the storeroom, a phone in front of the original. Nothing is downloaded to the device, which also means the model itself never leaves the Hub's custody: a point that matters when rights and reproduction are at stake.

Open it with View 3D from any model in 3D Assets, or from the work's record in the Catalog.

Turning the work in your hands

• Rotate and pan, with touch and pinch on tablets and phones.
• Zoom in to the tool marks, out to the whole figure; reset returns to the canonical view.
• Choose the centre of rotation and save it as the work's default presentation.
• Pivot tools for precise placement, with the possibility of saving a new version of the model from the adjusted state.

Annotating conditions and observations

• Comments anchored to the surface: a single point, or a drawn area (flat, or following the relief), each in its own color. A condition note, an attribution question, an instruction to the restorer: each remains exactly where it belongs, and the discussion stays with it.
• Review: collections that examine incoming scans formally can approve or reject each one from within the viewer.

Sections and details

In editor mode the viewer serves the conservator's harder questions:

• Selection by lasso, rectangle, base plane or whole object.
• Cuts through the front face only, or through the full body of the object; selections can be inverted.
• Full undo and redo, with recovery of unsaved sessions.
• Export of the cut as a working file (OBJ with materials and texture), or adoption of the cut as the model's default state.

Layers and spectral views

• Overlay of several models in one scene: states before and after treatment, fragments recomposed, casts against originals.
• Multispectral view: where spectral captures exist, the same work can be switched to its infrared and ultraviolet layers, and the underdrawing read in place.

The record at hand

A side panel keeps the model's details and processing history in view, and the work's full record (inventory, materials, dimensions, rights) is one step away in the Catalog. The viewer shows the object; the register answers for it.
