2D Preview and Hover Inspection

The 2D preview is the colour result used by the active modelling session. It also drives colour selection, connected-region detection, and layer inspection; it is not merely a thumbnail.

Inspecting detail

• Use the wheel or trackpad to zoom from 50% to 1000%.
• Drag with the right mouse button to pan; double-click to reset the view.
• Hold the comparison button, or hold Shift outside an input, to show the uploaded original.
• Releasing the button or Shift, or moving focus away from the window, restores the processed result.

Pixel-crisp rendering keeps actual preview boundaries visible at high zoom instead of smoothing them away.

Hover inspector

Hovering over the image can show:

• the pixel coordinate;
• predicted surface colour;
• the colour at the same point in every optical layer;
• either the magnifier or layer data when the other display toggle is off.

Layer images are loaded only when first needed. Transparent pixels and layers with no material are not assigned a fake colour. These are Lumina recipe layers, not proof of the slicer's final filament-slot assignment.

Cyan outlines

Clicks follow the active selection mode. Single- and multi-region modes send the real pixel coordinate to connected-component detection; All highlights the selected matched colours across the image.

When a selection originates from one gradient region, the workstation uses the exact spatial mask returned by the backend. It does not outline every other pixel with the same HEX value, preventing a local gradient band from looking like a whole-image selection.
