<div>David,</div>
<div>I really appreciate your response. I'll try your suggestions (it may be a while though).</div>
<div> </div>
<div>In my case z is NOT strictly a function of (x,y). The information primarily comes from seismic analysis. Fault could be thought of as a discontinuity of information at similar 'z' level because of seismic activity (as shown in the website <a href="http://www.iris.edu/gifs/animations/faults.htm">http://www.iris.edu/gifs/animations/faults.htm</a>).</div>

<div>Thanks again,</div>

<br>So you have a terrain map, where z is strictly a function of (x,y)?<br>And for some (x,y), the z value is not defined (the "fault" points).<br>How is the topology defined currently? Is it a set of triangles on the<br>
points?<br><br>This example demonstrates this type of terrain map surface.<br><a href="http://www.cmake.org/Wiki/VTK/Examples/Filtering/Delaunay2D" target="_blank">http://www.cmake.org/Wiki/VTK/Examples/Filtering/Delaunay2D</a><br>
<br>To create your faults, you can used a constrained triangulation:<br><a href="http://www.cmake.org/Wiki/Constrained_Delaunay_Triangulation_(2D)" target="_blank">http://www.cmake.org/Wiki/Constrained_Delaunay_Triangulation_(2D)</a><br>
<br>Take a look at these examples and see where they get you. If you still<br>have trouble don't hesitate to ask.<br><br>Good luck,<br>
