Constructor & Destructor Documentation

VRS::PickingCallback::PickingCallback	(	const SO< Callback1< IntersectionInfo * > > &	callback,
		const SO< Shape > &	shape = NULL,
		ButtonEvent::Button	button = ButtonEvent::MouseButton1,
		ButtonEvent::Change	action = ButtonEvent::Released,
		ButtonEvent::Modifier	modifier = ButtonEvent::NoModifier
	)

The given callback is called if the given shape is hit by the mouse pointer and the given conditions (mouse button, mouse action, and additional modifier key) are satisfied. The argument of the callback is an intersection info object (see IntersectionInfo) obtained by a ray query (see RayQuery). If no shape is specified, the callback is called for each shape.

VRS::PickingCallback::PickingCallback	(	const SO< Callback1< IntersectionInfo * > > &	callback,
		const SO< Iterator< SO< Shape > > > &	shapes,
		ButtonEvent::Button	button = ButtonEvent::MouseButton1,
		ButtonEvent::Change	action = ButtonEvent::Released,
		ButtonEvent::Modifier	modifier = ButtonEvent::NoModifier
	)

The given callback is called if one of the given shapes is hit by the mouse pointer and the given conditions (mouse button, mouse action, and additional modifier key) are satisfied. The argument of the callback is an intersection info object (see IntersectionInfo) obtained by a ray query (see RayQuery).
