Constructor & Destructor Documentation

FMMatrix33::FMMatrix33 (  float *  _m  )

Creates a FMMatrix33 from the float array. The float array stores the elements in the following order: m[0][0], m[1][0], m[2][0], m[0][1], m[1][1], m[2][1], m[0][2], m[1][2], m[2][2]. Parameters: _m  The float array to create the matrix from.

FMMatrix33::FMMatrix33 (   )  [inline]

Creates an empty FMMatrix33. The default values are non deterministic.
