ViewOrientation3D

Constructor

Description:
Constructs a new ViewOrientation3D using the input eye position, up and forward directions.

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

Parameter	Type	Description
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.

Return Value

Exceptions

Exception	Condition
ArgumentException	One or both of the input vectors cannot be normalized.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	upDirection has zero length. -or- forwardDirection has zero length.
ArgumentsInconsistentException	The vectors upDirection and forwardDirection are not perpendicular.
