Problem: I am trying to display a 3D solid object together with its respective XY, YZ, ZX planes as 2D graphics. It does not matter if the four graphics is displayed in one graphic widget, or as four separate widgets which have their separate graphic manipulation methods (eg. display(), reshape()). Any suggestion is highly appreciated.

GUI: Tcl/Tk
Extension to bind OpenGL to Tcl/Tk: Togl
Platforms: Solaris/HPUX/NT
