Spatial2DView

For viewing spatial 2D data.

Properties properties

background background

Configuration for the background of the view.

  • kind: The type of the background. Defaults to BackgroundKind.GradientDark.
  • color: Color used for BackgroundKind.SolidColor.

visual_bounds visualbounds

The visible parts of the scene, in the coordinate space of the scene.

Everything within these bounds are guaranteed to be visible. Somethings outside of these bounds may also be visible due to letterboxing.

time_ranges timeranges

Configures which range on each timeline is shown by this view (unless specified differently per entity).

If not specified, the default is to show the latest state of each component. If a timeline is specified more than once, the first entry will be used.
