Math Functions

The math library provided by the Direct3D extensions (D3DX) utility library supplies functions to compute 3-D mathematical operations. Each of the functions can take the same object as the passed [in] and returned [out] parameters. Also, out parameters are typically returned as return values, so that the output of one math function can be used as a parameter for another math function.

The 3-D math application functions can be organized into the following groups.
