Returns ArcRotateCameraPointersInput
Properties
angular
Defines the pointer angular sensibility along the X axis or how fast is the camera rotating.
angular
Defines the pointer angular sensibility along the Y axis or how fast is the camera rotating.
buttons
Defines the buttons associated with the input to handle camera move.
camera
Defines the camera the input is attached to.
multi
Defines whether panning is enabled for both pan (2 fingers swipe) and zoom (pinch) through multitouch.
multi
Defines whether panning (2 fingers swipe) is enabled through multitouch.
panning
Defines the pointer panning sensibility or how fast is the camera moving.
pinch
pinchDeltaPercentage will be used instead of pinchPrecision if different from 0. It defines the percentage of current camera.radius to use as delta when pinch zoom is used.
pinch
Revers pinch action direction.
pinch
Defines the pointer pinch precision or how fast is the camera zooming.
pinch
Defines whether zoom (2 fingers pinch) is enabled through multitouch
use
When useNaturalPinchZoom is true, multi touch zoom will zoom in such that any object in the plane at the camera's target point will scale perfectly with finger motion. Overrides pinchDeltaPercentage and pinchPrecision.
StaticMinimum
The minimum radius used for pinch, to avoid radius lock at 0
