I'm sorry I can't guide you to the right examples, but vtkColorTransferFunction and vtkPiecewiseFunction are part of this effort, and I see there are both tests and examples linked from the Doxygen pages that may get you someplace:</div><div><br></div><div><a href="http://www.vtk.org/doc/nightly/html/classvtkColorTransferFunction.html">http://www.vtk.org/doc/nightly/html/classvtkColorTransferFunction.html</a></div><div><a href="http://www.vtk.org/doc/nightly/html/classvtkPiecewiseFunction.html">http://www.vtk.org/doc/nightly/html/classvtkPiecewiseFunction.html</a></div><div><br></div><div>These were developed for the 3DSlicer application, which is also an open-source project. I've never looked at the code, but it's at least possible that it may be easier to grab something from there rather than ParaView...</div><div><br></div><div><a href="http://www.slicer.org/">http://www.slicer.org/</a></div><div><br></div><div>Hope this at least gets you started on pursuing another possibility,</div><div>-Eric</div><div><br><div>
