[vtkusers] Performance in plotting radar data with Vtk

I am trying to plot some radar data in real-time with VTK, due to a complete
lack of knowledge with OpenGl. I have an output that looks pretty much how I
want, however the performance is a bit sluggish.
Attached is a small test bed, as well as the plotting library I am using.
The testbed generates random data in the format we receive it.
I have two questions:
+ how do I colour the data based on it's value? I can warp it in the Z plane
fine, but colouring is beyond me :(
+ how can I improve the performance? I'm sure there are much better ways to
do some of this...
If you have a moment, please try running TestPlotting, then let me know
where I could improve performance, or where I can improve the approach
Thanks in advance for any advice.
As a comparison, the render time is about 0.7s on my 1.8Ghz laptop.
