RhinoViewportSetCameraDirection Method

Set viewport camera direction. By default the target location is changed so that the vector from the camera location to the target is parallel to the camera direction.

Namespace:  Rhino.Display
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 5.0
public void SetCameraDirection(
	Vector3d cameraDirection,
	bool updateTargetLocation


Type: Rhino.GeometryVector3d
new camera direction.
Type: SystemBoolean
if true, the target location is changed so that the vector from the camera location to the target is parallel to the camera direction. If false, the target location is not changed. See the remarks section of RhinoViewport.SetTarget for important details.
