Description:

The Mayavi project includes two related packages for 3-dimensional
visualization:

* Mayavi2: A tool for easy and interactive visualization of data.
* TVTK: A Traits-based wrapper for the Visualization Toolkit, a
popular open-source visualization library.

These libraries operate at different levels of abstraction. TVTK
manipulates visualization objects, while Mayavi2 lets you operate on
your data, and then see the results. Most users either use the Mayavi
user interface or program to its scripting interface; you probably
don't need to interact with TVTK unless you want to create a new
Mayavi module.
