3D Viewer

Merge several GLB files into one scene and view it at night or at any time of day.

Loaded files

Two files carry luminaires. If they describe the same installation — say as IES and as point spot — the light is in the picture twice.

Variant comparison

The states one after the other, same camera and same exposure. The exposure is derived once from the reference and then stays put — otherwise each variant would be calibrated to itself and all would look equally bright. The value next to it says how many stops brighter or darker a variant is than the reference.

The graphics card lost its connection. This happens with large models on weak graphics — the preview cannot keep drawing.

The preview only computes as many as the frame rate carries, and which ones was decided before the last switch. Recomputing takes up to a minute on large models.

Set up first, then load: trades, comparison, light and time all take effect at build time — so it is computed once instead of twice.

Date

Sun position from the georeference in the file. The presets target a sun altitude, not a clock time — the same state on any date.

Red X · green Y · blue Z at the model origin. Per luminaire: yellow arrow = aim, red line = C0 plane.
