[Paraview] Further questions regarding 4D dataset

[Jérôme]

Richard,
These steps make the MIP available by me :
- open ParaView
- Add MIP.py as macro ( menubar "Macros" -> "Add new macro"). as you noted,
it adds a button in the toolbar
- Open a volume (or add a volume source, eg Wavelet) and click on "Apply"
- Change the representation to Volume ("Object inspector" panel -> "Display"
tab -> "Style" frame -> "Representation" combobox -> "Volume"). You may want
to choose GPU rendering : "Volume Mapper" -> GPU
- Click on the newly added MIP button. Normally, it should change the volume
representation to MIP one.

If you want to go back to the usual volume rendering, do the same with the
Composite.py macro.
