Matrix.PerspectiveFovRH Method |
Language: |
Builds a right-handed perspective projection matrix based on a field of view (FOV).

fieldOfViewY System.Single. Field of view in the y direction, in radians. aspectRatio System.Single. Aspect ratio, defined as the view space width divided by height. znearPlane System.Single. Z-value of the near view plane. zfarPlane System.Single. Z-value of the far view plane.
Microsoft.DirectX.Matrix . A Matrix structure that is a right-handed perspective projection matrix.
This method uses the following formula to compute the returned matrix. The view space height is represented by h. It is calculated from h = cot(fieldOfViewY/2). The view space width is represented by w. It is calculated from h = w / aspectRatio.
w 0 0 0 0 h 0 0 0 0 zfarPlane/(znearPlane-zfarPlane) -1 0 0 znearPlane*zfarPlane/(znearPlane-zfarPlane) 0
