viewers. However, note that due to the differencies between underlying API
of OCC and VTK libraries the behaviour of the functionality related to

values for each component of light independently.

-If the material model is specified as a \em physical one (like \em Gold,
-for instance), this means that the color of the shape (more precisely
-its \em ambient color) can not be modified. If you assign a physical
-material model to the shape, the "Color" menu item will not be
-available in the popup menu.

-If the model is non-physical (\em artificial), the color can be changed
-to any appopriate one, only other attributes will be constant. In the
-dialog box you will be able to modify the color of the shape via the
-"Color" button. "Ambient color" button becomes disabled to signalize
-that this attribute of the model is ignored. Also, it will be possible
