represent a contour drawn on the focal plane.
<p>
The contour will stay on the focal plane irrespective of camera position/orientation changes. The class was written in order to be able to draw contours on a volume widget and have the contours overlayed on the focal plane in order to do contour segmentation. The superclass, <a class="el" href="a00326.html" title="represent the vtkContourWidget">vtkContourRepresentation</a> handles contours that are drawn in actual world position co-ordinates, so they would rotate with the camera position/ orientation changes<p>
