Microsoft.DirectX.Matrix . A Matrix structure that is a customized, left-handed orthogonal projection matrix.
An orthogonal matrix is an invertible matrix for which the inverse is equal to the transpose.
The OrthoLH method is a special case of the OrthoOffCenterLH method. To create the same projection using OrthoOffCenterLH, use the following values: left = -width/2, right = width/2, bottom = -height/2, and top = height/2.
All of the parameters of the OrthoOffCenterLH 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/(right-l) 0 0 0 0 2/(top-bottom) 0 0 0 0 1/(zfarPlane-znearPlane) 0 (l+right)/(l-right) (top+bottom)/(bottom-top) znearPlane/(znearPlane-zfarPlane) 1
