    public class TransformMatrix4f
extends java.lang.Object
implements java.io.Serializable
    special form of a 4x4 matrix. first of all the way we represent the matrix in this class is similar to the way opengl handles the row column issue. transform matrix -- r = rotation, t = translation rxx rxy rxz 0 ryx ryy ryz 0 rzx rzy rzz 0 tx ty tz 1 the transform matrix is special in the way that is a 3x3 matrix for rotation and scale and a translation vector. the remaining four values a constants. this is the way opengl specifies a 4x4 matrix and also the way 'toArray' returns an array. m[0] m[4] m[8] m[12] m[1] m[5] m[9] m[13] M=( ) m[2] m[6] m[10] m[14] m[3] m[7] m[11] m[15] here is an excerpt from the glMultMatrix man page. "In many computer languages 4x4 arrays are represented in row-major order. The transformations just described represent these matrices in column-major order. The order of the multiplication is important. For example, if the current transformation is a rotation, and glMultMatrix is called with a translation matrix, the translation is done directly on the coordinates to be transformed, while the rotation is done on the results of that translation." also read 'The Matrix and Quaternions FAQ' at http://www.flipcode.com/documents/matrfaq.html
