How to draw

Some toggles define how to draw the surfaces selected by the toggles ``What to draw''. Theses toggles are:

• ``mesh'': the mesh of the surface must be drawn if this toggle is on.
• ``Ivalue'': the surface must be colored with the current colormap and the values associated with the current variable.
• ``Ilines'': isolines on the surface must be drawn for the values associated with the current variable.
• ``painter'': the surfaces must be drawn in the painter mode.

With the loaded example data (``ex_2b3d.desc''), you can set the ``comp fr'' and ``painter'' toggles on and press the ``redraw'' button to show the image presented by the figure 1.27.
