// a set of routines that let you do common 3d math // operations without any vector, matrix, or quaternion // classes or templates. // // a vector (or point) is a 'NxF32 *' to 3 floating point numbers. // a matrix is a 'NxF32 *' to an array of 16 floating point numbers representing a 4x4 transformation matrix compatible with D3D or OGL // a quaternion is a 'NxF32 *' to 4 floats representing a quaternion x,y,z,w // // /*! ** ** Copyright (c) 2009 by John W.
