Pivy is a Coin binding for Python. Coin is a high-level 3D graphics library with a C++ API. Coin uses scene-graph data structures to render real-time graphics suitable for mostly all kinds of scientific and engineering visualization applications. Pivy allows:

* Development of Coin applications and extensions in Python
* Interactive modification of Coin programs from within the
Python interpreter at runtime
* Incorporation of Scripting Nodes into the scene graph which
are capable of executing Python code and callbacks
* Use of Coin within PyQt4 applications with the quarter module
