[vtkusers] vtk vs pyvtk vs coin3d memory usage

[Zach]

Hello:

I was reading through the IVuPy <http://ivupy.sourceforge.net/> page
regarding comparisons between vtk and coin3D. It mentioned that the python
implementation (I assume) of vtk used significantly more memory than
coin3D. Here is the statement:

"A program using the Python bindings of VTK <http://www.vtk.org/> needed an
order of magnitude more memory and time than a C++ program using Coin3D to
display the surfaces. The author of the VTK based Python program may not
have seen how to handle large dat
<http://www.vtk.org/Wiki/VTK_FAQ#How_to_handle_large_data_sets_in_VTK>a
sets in VTK
<http://www.vtk.org/Wiki/VTK_FAQ#How_to_handle_large_data_sets_in_VTK>, but
Coin3D got it right by default."

So, I am wondering if this is simply a case of the difference in speed
between C++ and Python; or if it is actually a case of proper
implementation of Python wrappers, has this issue been remedied? Thanks for
the help.

Regards,

Zach
