);
C++ public:
static Matrix PerspectiveOffCenterLH(
    float left,
    float right,
    float bottom,
    float top,
    float znearPlane,
    float zfarPlane
);
JScript public static function PerspectiveOffCenterLH(
    left : float,
    right : float,
    bottom : float,
    top : float,
    znearPlane : float,
    zfarPlane : float
) : Matrix;

Parameters

left System.Single
Minimum x-value of the view volume.
right System.Single
Maximum x-value of the view volume.
bottom System.Single
Minimum y-value of the view volume.
top System.Single
Maximum y-value of the view volume.
znearPlane System.Single
Minimum z-value of the view volume.
zfarPlane System.Single
Maximum z-value of the view volume.

Return Value

Microsoft.DirectX.Matrix
A Matrix structure that is a customized, left-handed perspective projection matrix.

Remarks

All of the parameters of the PerspectiveOffCenterLH 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/(right-left)  0                           0                                            0
0                          2*znearPlane/(top-bottom)   0                                            0
(left+right)/(left-right)  (top+bottom)/(bottom-top)   zfarPlane/(zfarPlane-znearPlane)             1
0                          0                           znearPlane*zfarPlane/(znearPlane-zfarPlane)  0
