One might want to change attributes of the visualization directly with the mouse. But for subsequent visualizations, one does not want to go through all the property setting again, and rather would like to add the changes as scripting commands.
This is possible using the record mode of Mayavi. The following series of images makes this clear.
Click in the menu bar on View -> Other.
Select the Mayavi Visualization Tree.
Now, click on the red button to activate the record mode. A window pops up.
Do your modifications to your visualization now. For example, here we select an arrow glyph source for our current 3D View.
See the automatically generated scripting output in the recording window
You can copy and paste the relevant code now into your own script. This would be Line 12 and 13 in our case.
One might have to adapt the output script in some cases, for example when you have many 3D View visualizations open for many networks. In line 12, it would read engine.scenes[XX]... with XX being the view you want to manipulate.
The visualization objects (like vectors above) are also accessible using the render manager of an activated networks.
Type in the IPython shell:
cfile.networks[0].rendermanager.print_traits()
In our case above, the vectors variable refers to the same objects as:
cfile.networks[0].rendermanager.vectors
That’s it for this tutorial. If you want to go more in-depth of Mayavi scripting, see the Mayavi documentation. Happy visualization scripting!
