1 · Load any GLB

Choose a GLB to inspect.

No model loaded.

Local recovery

Checking this device for a saved session…

Private to this browser on this device. CoLab stores the original GLB, selections, paint, and poses locally when space allows. Nothing is uploaded. JSON exports remain your portable backup; previous paint undo history and comparison GLBs are not restored.

App updates · version 0.11

Updates never interrupt active work automatically.

Six-color geometry selections and agent handoffs · B3.3 preserved

2 · Surface selection

Tap a visible surface in Select mode.

Auto-select connected part when tapping

Uncheck for individual triangles. A numbered, color-coded marker shows the exact surface tap even if a tiny triangle is hard to see. Use Connected part to expand the active region again.

3 · Six independent color selections

Active region name

Choose a color, tap geometry and expand to Connected part. Select another color to keep both regions visible. You can name each region. This is for inspection, not yet expression editing. B2.1/B3.1: tapping auto-expands connected geometry, and each color slot remembers its hit.

4 · Selection visibility

Surrounding geometry visibility 20%

Isolate shows selected triangles, optionally with faded surroundings. Hide selected shows all other triangles. Restore all to select another surface. Selection and original geometry remain intact.

5 · Selection appearanceUnselected geometry transparency 0%

7 · Agent handoff

📷 Work with your AI agent · screenshots can prevent wasted rebuilds

Try the model, share a screenshot of what happened and describe what looks wrong in ordinary words. Your agent can compare before/after images, repair a small reusable script, and ask you to retest instead of repeatedly rebuilding or regenerating the whole asset.

This can reduce unnecessary paid AI calls or generations, but savings depend on your tools and usage; image analysis may also be metered. Read our screenshot-first workflow and example prompt ↗

Selection labelInstructions / observationsRestore selection JSONAdd to current selection instead of replacing (matching GLB only)

Handoff records a SHA-256 fingerprint of the original GLB, a mesh path, triangle indices, UVs when present, and 3D hit location. Import refuses a different file fingerprint. Original model data is never rewritten.

Scope and limitations

Milestone A includes universal inspection, triangle selection, connected-component selection using shared geometric edges, mesh selection, display modes, camera presets, and JSON save/restore. Large selections may be slow on phones. Connected parts are determined by matching position edges within a small tolerance, so near-coincident seams may connect or stay separate depending on geometry. This test hides or isolates selected source triangles in the viewer without editing GLB geometry; previews are rebuilt as lightweight meshes and may not follow animated/skinned deformation. Painting and geometry edits remain future milestones.
