<h3>View</h3>
You can use this panel to set the <em>position, direction, and
- perspective</em> of the view. The position box shows a puck with a
- direction line pointing to the center. The direction line indicates
- the look direction (azimuth). You click and drag the puck to change
- the current eye position. Another way to change eye position is
- to press the buttons around the position box representing cardinal
- and ordinal directions.

Cutting planes allow to cut surfaces along a plane. You can switch
between six planes; to disable cutting planes switch to <em>None</em>.
-Initially the plane is vertical, you can change it to horizontal by setting
-<em>tilt</em> 90 degrees. The <em>X</em> and <em>Y</em> values specify

In case of multiple surfaces you can visualize the cutting plane by
<em>Shading</em>. Shading is visible only when more than one surface
is loaded and these surfaces must have the same fine resolution set.
