Hi all,
I need to develop a GUI for some scientific data processing operations
and this GUI should work well with a 3D plotting module, also with NumPy
and SciPy for sure. I made a search about packages but, there are plenty
of these modules available. What kind of a package or a package of
packages might be the best way for this work. BTW I do not want to use
MayaVi. It is too much actually.
Thanks in advance.

The attached example should give you some idea of embedding mayavi (and
then using the very high-level mlab) and vtk in wxpython apps. This
example requires wxpython, vtk, numpy, and ETS. If you are really after
visualization of data, you will need to spend years to get even a
fraction of the capability of mayavi. On the other hand, rolling out a
py2exe'd version of a program is currently a major challenge if you need
ETS.
The mayavi.mlab module is so easy to use and embed that I would
recommend using it to create a rapid software prototype to compare
against whatever system you decide to go with. It is designed with a
seamless interface to numpy/scipy, and provides high-level routines to
modify low-level properties.
Cheers,
Eric

This example show how to embedded Mayavi in a wx aui notebook, and
also shows how to embed a generic vtk window
This is a slightly more complex example than the wx_embedding.py one, and
can be used to see how a large wx application can use different
Mayavi views.
