Builds a right-handed perspective projection matrix.

Namespace: Microsoft.WindowsMobile.DirectX
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Shared Function PerspectiveRH ( _
    width As Single, _
    height As Single, _
    znearPlane As Single, _
    zfarPlane As Single _
) As Matrix
'Usage
Dim width As Single
Dim height As Single
Dim znearPlane As Single
Dim zfarPlane As Single
Dim returnValue As Matrix

returnValue = Matrix.PerspectiveRH(width, _
    height, znearPlane, zfarPlane)

public static Matrix PerspectiveRH(
    float width,
    float height,
    float znearPlane,
    float zfarPlane
)

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

static member PerspectiveRH : 
        width:float32 * 
        height:float32 * 
        znearPlane:float32 * 
        zfarPlane:float32 -> 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 right-handed perspective projection matrix.

Remarks

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

This method uses the following formula to compute the returned matrix.

2*znearPlane/width  0                    0                                            0
0                   2*znearPlane/height  0                                            0
0                   0                    zfarPlane/(znearPlane-zfarPlane)            -1
0                   0                    znearPlane*zfarPlane/(znearPlane-zfarPlane)  0
