helper object to manage the visibility of points and cells
<p>
<a class="el" href="a01644.html" title="helper object to manage the visibility of points and cells">vtkStructuredVisibilityConstraint</a> is a general class to manage a list of points/cell marked as invalid or invisible. Currently, it does this by maintaining an unsigned char array associated with points/cells. To conserve memory, this array is allocated only when it is needed (when <a class="el" href="a01644.html#bafc8710ba22eb06ea2c74a5dc0b942b">Blank()</a> is called the first time). Make sure to call <a class="el" href="a01644.html#efddeafe845888523a84f105b6bb8824">Initialize()</a> with the right dimensions before calling any methods that set/get visibility.
