XMMatrixPerspectiveOffCenterRH method
Builds a custom version of a right-handed perspective projection matrix.
Syntax
XMMATRIX XMMatrixPerspectiveOffCenterRH( [in] float ViewLeft, [in] float ViewRight, [in] float ViewBottom, [in] float ViewTop, [in] float NearZ, [in] float FarZ );
Parameters
- ViewLeft [in]
-
The x-coordinate of the left side of the clipping frustum at the near clipping plane.
- ViewRight [in]
-
The x-coordinate of the right side of the clipping frustum at the near clipping plane.
- ViewBottom [in]
-
The y-coordinate of the bottom side of the clipping frustum at the near clipping plane.
- ViewTop [in]
-
The y-coordinate of the top side of the clipping frustum at the near clipping plane.
- NearZ [in]
-
Distance to the near clipping plane. Must be greater than zero.
- FarZ [in]
-
Distance to the far clipping plane. Must be greater than zero.
Return value
Returns the custom perspective projection matrix.
Remarks
For typical usage, NearZ is less than FarZ. However, if you flip these values so FarZ is less than NearZ, the result is an inverted z buffer which can provide increased floating-point precision. NearZ and FarZ cannot be the same value.
Platform Requirements
Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
