model calibration harness · M1.5
load a model → pick the screen mesh → tune → export model.manifest.json

1 · Model source

Built-in procedural model

External .glb file

Uncompressed GLB only (no Draco/KTX2/meshopt on three r128). Drag & drop onto the viewport also works.

2 · Normalize & pose

targetSize (footprint)

rotationY (deg)

3 · Screen mesh

mesh (auto-detected candidates marked ●)

highlight selected mesh

screen width (px)

screen height (px)

glow color

flipY

The test pattern says ▲ TOP. If it reads upright on the screen in the viewport, orientation is correct. If upside-down, toggle flipY.

4 · Brand

brand name

tagline

version

5 · Export

inline model as base64 (single-file HTML)

Leave unchecked for an external manifest (place the .glb next to your built HTML). Inline embeds the whole GLB (kept out of git; watch the 10–15 MB single-file budget).
