Interface DragManagerOptions

Camera the drag maths run against. Defaults to the pointer input's camera, which is what resolved the pointer in the first place — pass one only to override that deliberately.

Clip-space depth convention of that camera's projection (plan D8). Defaults to "negative-one-to-one" via createPickRay. It cancels out of the delta (both unprojections use it), so it matters only for the perspective depth measurement.

Receives the world-space displacement since the previous move of this drag.

The vector is reused between calls (plan D7) — read it or copy it, never keep it. The manager never writes a transform: see the module documentation.

Called when a drag ends — on release, on DragManager.releaseDrag, and on disposal. Takes no event, because a programmatic release has none.

Called when a drag begins, before any DragManagerOptions.onDrag.

The pointer source whose events drive drags. Its setPointerCapture is what keeps a drag alive when the pointer leaves the node.
