Re: [JAVA3D] Let me try to say this more clearly

[Kyle Wayne Kelly]

Clarification:  I can easily translate the vrp to the world coordinate origin.  I just want to rotate the viewer's coordinate system so that the axis coincides with the world coordinate system.  Does it have to do with calculating the projection, and then doing the cross product?  I am in dire straits.  Any help is greatly appreciated.    /**   * Kyle Wayne Kelly   * Computer Science Student   * University of New Orleans   * 504-391-3985   * http://www.cs.uno.edu/~kkelly   * Glory to God!   * El temor del hombre pondra lazo;   * Mas el que confia en Jehova sera exaltado.
