The interweb has been my friend when it comes to researching 3d image libraries.  It is also my sole source for learning to use python, so what I’m about to share can be found if one has a bit of free time to go poking around and do some searching.  However, I wanted to bring this to everyone’s attention.  There is a 3D graphics library for python called Pyvy.  Pivy is a python binding of the Coin toolkit and makes the development of 3D objects in Python a rapid process.  It can even be used from within the python interpreter immediate mode window so you can get immediate feedback, from what I’ve read.  This seems relevant to our project for obvious reasons, but I wonder if this functionality overlaps with blender, to the point that we may not need such a library?  Any thoughts?  There is a useful article with code examples on how to use some of Pivy’s basic features that can be found here, and The project site can be found here.  I took a quick glance at the license for this library and it appears to be freely available for distribution, if we choose to implement it in our software.  The source code is also available.
