Relative movements of a tool and a workpiece are controlled by moving a tool axis in all spatial dimensions for the material-removal machining of the workpiece to produce a desired target contour of the workpiece by a sequence of relative movements along a tool trajectory of the tool. The subpanel has a plurality of electrical connectors 28 which are user accessible thereby. Such electron transfer rates are useful in smart drug design and enzyme engineering. Sources of illumination are then inferred, conditioned on the estimated scene geometry and surface materials and without any user input, to form a complete 3D physical scene model corresponding to the image. Of course, other combinations are provided and claimed as well. The panel is positioned parallel with the polarizing unit within the inner space so that the LED devices face towards the polarizing front unit.
