Interface: SubplotViewportOptions

Experimental

A non-cartesian subplot's own viewport (M6: 3D scenes; GEO2: map projections; ADR-004), from TracePlotContext.subplotViewport / ComponentDrawContext.subplotViewport.

Properties

Property	Modifier	Type	Description
background?	readonly	RGBA | null	Experimental Painted under the subplot (sRGB 0–1); null or unset for none.
kind?	readonly	"2d" | "3d"	Experimental '3d' (the default) has a perspective or orthographic camera and a depth buffer. '2d' is a pixel-space viewport like a cartesian subplot's (ADR-008): world units are CSS px from the rect's bottom-left corner, y up. Fixed by the first call for a key.
projection?	readonly	"orthographic" | "perspective"	Experimental 3D only. Default 'perspective'; a change swaps the camera (Viewport.setProjection).
rect	readonly	Readonly<ViewportRect>	Experimental Rect in container px (top-left origin); the viewport clips to it.
