width System.Single. Width of the view volume. height System.Single. Height of the view volume. znearPlane System.Single. Minimum z-value of the view volume, which is referred to as z-near. zfarPlane System.Single. Maximum z-value of the view volume, which is referred to as z-far.
Microsoft.DirectX.Matrix . Pointer to a Matrix structure that is a left-handed orthogonal projection matrix.
An orthogonal matrix is an invertible matrix for which the inverse is equal to the transpose.
All of the parameters of the OrthoLH 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/width 0 0 0 0 2/height 0 0 0 0 1/(zfarPlane-znearPlane) 0 0 0 znearPlane/(znearPlane-zfarPlane) 1
