)

public:
static Matrix PerspectiveLH(
    float width, 
    float height, 
    float znearPlane, 
    float zfarPlane
)

public static function PerspectiveLH(
    width : float, 
    height : float, 
    znearPlane : float, 
    zfarPlane : float
) : Matrix

Parameters

width
Type: System.Single

Width of the view volume at the near view plane.

height
Type: System.Single

Height of the view volume at the near view plane.

znearPlane
Type: System.Single

Z-value of the near view plane.

zfarPlane
Type: System.Single

Z-value of the far view plane.

Return Value

Type: Microsoft.WindowsMobile.DirectX.Matrix
A Matrix structure that is a left-handed perspective projection matrix.

Remarks

All of the parameters of the PerspectiveLH method are distances in camera space. The parameters describe the dimensions of the view volume.
