Syntax
public ViewOrientation3D(
	XYZ eyePosition,
	XYZ upDirection,
	XYZ forwardDirection
)
Public Sub New ( 
	eyePosition As XYZ,
	upDirection As XYZ,
	forwardDirection As XYZ
)
public:
ViewOrientation3D(
	XYZ^ eyePosition, 
	XYZ^ upDirection, 
	XYZ^ forwardDirection
)
new : 
        eyePosition : XYZ * 
        upDirection : XYZ * 
        forwardDirection : XYZ -> ViewOrientation3D

Parameters

eyePosition  XYZ
The eye position
upDirection  XYZ
The up direction. This vector will be normalized. Up direction must be perpendicular to the forward direction.
forwardDirection  XYZ
The forward direction. This vector will be normalized. Forward direction must be perpendicular to the up direction.
