Member Function Documentation

boolean org.hfbk.vis.visnode.VisNodeDraggable.hit	(	Ray	mouseray,
		Vector3f	hit
	)			`[package]`

we introduce a slightly faked hit surface: the hit plane is Wiewpoint aligned to allow intuitive dragging of objects in screen plane.

precisely, the hit plane is tangential to a camera centered sphere.

after first hit, we fix the distance to get a solid dragging experience even if the handle point leaves the hit plane due to the gap between the tangential plane and the real sphere surface.
