What to draw

Some toggles define what to draw when you press the ``redraw'' button. These toggles are:

• ``name'': the name of the solution appears in the top left corner of the drawing window,
• ``global bb'': a bounding box global to all solution is drawn in each solution window.
• ``local bb'': define a bounding box for each solution,
• ``3D axes'': draw the $x, y, z$ axes.
• ``skeleton'': intersection of the user frontier with parallel planes,
• ``user fr'': the user defined frontier.
• ``comp fr'': the computed frontier for each block.
• ``planes'': all the plane meshes computed by intersecting the volume by planes are drawn.
• ``isos'': all the computed isosurfaces are drawn.
• ``csurf'': all the computed surfaces, produced from operation executed on other surfaces, are drawn.
• ``usdurf'': reference all the ``user defined surfaces'', see the chapter 2.
