IDCompositionDevice::CreateMatrixTransform3D method (dcomp.h)
Creates a 3D 4-by-4 matrix transform object.
Syntax
HRESULT CreateMatrixTransform3D(
[out] IDCompositionMatrixTransform3D **matrixTransform3D
);
Parameters
[out] matrixTransform3D
Type: IDCompositionMatrixTransform3D**
The new 3D matrix transform object. This parameter must not be NULL.
Return value
Type: HRESULT
If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.
Remarks
The new 3D matrix transform has the identity matrix as its value. The identity matrix is the 4-by-4 matrix with ones on the main diagonal and zeros elsewhere, as shown in the following illustration.
When an identity transform is applied to an object, it does not change the position, shape, or size of the object. It is similar to the way that multiplying a number by one does not change the number. Any transform other than the identity transform will modify the position, shape, and/or size of objects.
