	SbVec3f up
)

Public Sub ViewAxis (

	up As SbVec3f
)

public:
void ViewAxis(
	SbVec3f direction, 
	SbVec3f up
)

member ViewAxis : 
        direction : SbVec3f * 
        up : SbVec3f -> unit

Parameters

direction: Type: OIV.InventorSbVec3f
The new view direction vector: this is the vector from the camera's position to the target point. Any future call to the method OIV.Inventor.ViewerComponents.SoCameraInteractor.GetDirectionVector() will return the same vector.
up: Type: OIV.InventorSbVec3f
The new up direction vector
