Nested scene views

SceneView(child) turns a prepared child scene into one movable parent tattva. The child retains its own camera, frame, timeline, and local clock.

const inset = this.add(
  SceneView(new DiagramScene())
    .size(5.2, 3.1)
    .resolution(960, 540)
    .background("#10151f")
    .border(0.04, "#5cd0b3")
    .cornerRadius(0.18)
    .playback("once"),
  { at: [3.8, -1.5] },
);

Playback modes

Mode	Behaviour
"continuous"	Local time continues beyond the child's authored end.
"once"	Stops at the child duration.
"paused"	Holds at localTimeOffset.
{ loop: seconds }	Wraps local time over the specified duration.

.startAt(parentTime), .localTimeOffset(seconds), and .timeScale(factor) control the clock mapping. That mapping is a pure function, so seeking remains deterministic.

Scene views are useful for picture-in-picture explanations, before/after comparisons, dashboards, and displaying an orthographic scene inside a perspective parent.
