Math Functions

The math library provided by the Direct3DX utility library supplies functions to compute both basic and complicated 3-D mathematical operations.

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

Note  All of the math functions can take the same object as both the passed (in) and returned (out) parameters. Also, out parameters are typically returned as return values, so that the output of one math function may be used as a parameter for another math function.
