Hi,
A binary version of the "TransformWithAxis" filter is available in my
web page.
http://rom.research-centrale-nantes.com/resources/separated-variables-representation-visualisation/
The filter is inside a plugin called PXDMFReader. (version 1.5.1)
To test this filter you can create a Wavelet source and apply the filter
with an arbitrary translation/rotation/scale and then activate "Show
cube axes".
If you think this is a good improvement, I can send the sources.
Also 3 filters and a reader are available in the plugin but are more
related to our research.
