Hi Alan,<br>
<br>
The verbosity of the trace can be confusing, 90% of it is
unnecessary, and can be removed. Here's how it looks in your example
with unnecessary stuff removed and the 3 lines added to change the
lut by name.<br>
<tt><br>
</tt><tt>#### import the simple module from the paraview</tt><tt><br>
</tt><tt>from paraview.simple import *</tt><tt><br>
</tt><tt><br>
</tt><tt>#### disable automatic camera reset on 'Show'</tt><tt><br>
</tt><tt>paraview.simple._DisableFirstRenderCameraReset()</tt><tt><br>
</tt><tt><br>
</tt><tt># create a new 'Wavelet'</tt><tt><br>
</tt><tt>wavelet1 = Wavelet()</tt><tt><br>
</tt><tt><br>
</tt><tt># get active view</tt><tt><br>
</tt><tt>renderView1 = GetActiveViewOrCreate('RenderView')</tt><tt><br>
</tt><tt><br>
</tt><tt># uncomment following to set a specific view size</tt><tt><br>
</tt><tt># renderView1.ViewSize = [856, 797]</tt><tt><br>
</tt><tt><br>
</tt><tt># show data in view</tt><tt><br>
</tt><tt>wavelet1Display = Show(wavelet1, renderView1)</tt><tt><br>
</tt><tt><br>
</tt><tt># change representation type</tt><tt><br>
</tt><tt>wavelet1Display.SetRepresentationType('Surface')</tt><tt><br>
</tt><tt><br>
</tt><b><tt># change lookup table</tt></b><b><tt><br>

Alan,<br>
<br>
You can use the AssignLookupTable function to reference
builtin lookup tables by name. For example see code between #
marks below. There are a few other conveniences for working
with the builtin tables as well, see this

have a user that needs to change the ParaView preset
from default (cool to warm) to another ParaView preset
(Blue to Red Rainbow). He wants to do this in a python
trace. So, he used the trace recorder to record his
steps. Unfortunately, changing presets is not recorded
with the trace recorder.<o:p></o:p></span></p>
