+     *     but in Direct3D v' = v*N where N is the transpose of M
+     *
+     * (2) Invert the Z value in clipping coordinates because OpenGL
+     *     uses left-handed clipping coordinates, while Java3D defines
+     *     right-handed coordinates everywhere. i.e. do the following
+     *     after the transpose
+     *
+     *    d3dMatrix._13 *= -1;
+     *	  d3dMatrix._23 *= -1;
+     *	  d3dMatrix._33 *= -1;
+     *	  d3dMatrix._43 *= -1;
+     *
+     * (3) In Direct3D, the z-depths range is [0,1] instead of
+     *     OGL [-1, 1], so we need to multiple it by
+     *
+     *	        [1 0   0 0] 
+     *      R = [0 1   0 0] 
+     *	        [0 0 0.5 0]
+     *		[0 0 0.5 1] 
+     *
+     *     after the transpose and negate. i.e. N*R
+     *
+     * (4) We want w-friendly perspective matrix, i.e., d3dMatrix._34 = 1
+     *     We do this first by divide the whole matrix by
+     *     1/d3dMatrix._34 Since d3dMatrix._34 is always negative as
+     *     input from Java3D.  Now d3dMatrix._34 = -1
+     *
+     * (5) To make d3dMatrix._34 = 1, we negate the third row of it.
+     *     Because of this, we need to negate the third column in 
+     *     View matrix to compensate this.
