void ActivateOrbiting(
	SbVec2f startPos
)

member ActivateOrbiting : 
        startPos : SbVec2f -> unit 

Parameters

startPos

Type: OIV.InventorSbVec2f

starting position, 2D point in normalized screen coordinates (0 <= x,y <= 1). Typically this value is obtained from the SoEvent method getNormalizedPosition().

This method should be called when starting an interaction. Typically this is triggered by a mouse button or touch event. On subsequent mouse move or touch events, call the orbit() method with the new cursor or touch position.

Orbit is often used in an "examiner" type of viewer to allow the user to rotate the camera around a point of interest in the scene. To implement orbit around the camera's "focal point", call setRotationCenter() with the value returned from getFocalPoint().
