<p>Andrew, Cory,</p>
<p>Thanks for the attachment - as a non-coder it bridged the gap between the PDF that I've seen before and what actually needed to be done.</p>
<p>I've attached my trefoil knot code in a zip. The partial derivatives make a big difference to shadows.</p>
<p>I'm on Arch Linux with VTK 6.1.0, and the only change I needed to make to get the example to build was to the CMakeLists.txt - so it picks up OpenGL rather than OpenGL2.</p>
<p>I'm pleased that this works, but the output surface is rather jagged when compared to what I get with MathMod. Any ideas?</p>
<p>For the VTK user list, the zipped files I mention are here:</p>
<p><a href="https://github.com/logicmonkey/curves/tree/master/vtk/TrefoilKnot" target="_blank">https://github.com/logicmonkey/curves/tree/master/vtk/TrefoilKnot</a></p>
<p>( unzip/git pull; cd TrefoilKnot; mkdir build; cd build; cmake ..; make; ./bin/TrefoilKnot )</p>
<p>Thanks again for your help.</p>
<p>--</p>

Hi All,<br>
<br>
I'd like to specify a surface f(u,v) in 3D with my own parametric equation system {x(u,v), y(u,v), z(u,v)}. And then visualize it.<br>
<br>
The only way I can see to do this is to add my function to the library source code, build the library and then call my function as described here:<br>
<br>
<a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/ParametricObjectsDemo#CMakeLists.txt" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx/GeometricObjects/ParametricObjectsDemo#CMakeLists.txt</a></blockquote>

<div>Yep, that looks like a good way to go.</div>

I'm using vtkParametricTorus[.h, .cxx] as a template, but is there an easier and more direct way to do this?</blockquote>
<div> </div>
<div>You can define your subclass of vtkParametricFunction in your local project - no need to add it to VTK, which is what I think you were saying above.</div>
<div> </div>
<div>Were you looking for a vtkParametricFunction subclass that takes an expression for x(u,v), etc.? That doesn't exist as far as I know, but that would be cool to have.</div>
