As another poster pointed out below, VTK is a very strong vis tool. It is actively supported and has bindings to several languages (C++, Python, Java, and Tcl at last count). I have used the combination of python and VTK together to produce many scientific visualizations, including production quality animations (Usually, I use Python/VTK to generate isosurfaces or the like, and import the resulting geometry data into Maya or another high-quality renderer) One hurdle to overcome is transferring array data from Numeric/Numpy into VTK. I have a sort of ad-hoc method to do that (mainly for volume data). If anyone knows of any elegant solution, or a module to ease the pain, I'd like to hear about it. If you are working with NetCDF files, you may wish to add ScientificPython (distinct from SciPy) to your toolset. It has a very nice NetCDF interface. Unfortunately, it is ancient, and you would have to install Numeric Python (ancestor to NumPy). However, it is easy to convert Numeric arrays into Numpy arrays: >>> my_numpy_array=numpy.array(my_numeric_array) -matt -- http://mail.python.org/mailman/listinfo/python-list
