Yeh, although I haven't used the Blender scripting language, I use the one 
in my CAD program regularly to create parametric models that generate 
themselves based on a few core parameters.  For example if you were 
designing an engine, you could have a few variables like number of 
cylinders, cylinder bore, cylinder stroke etc, and then the CAD is 
automatically generated from those.  If you suddenly want to change the 
stroke then it's just a case of changing one number and then it's done.

Actually, come to think about it I remember using the scripting language in 
3D Studio Max.  THat was pretty flexible, allowing you to create and modify 
scene objects, as well as extracting data from them afterwards.  It 
obviously had a real-time 3D scene you could look around (like in Blender), 
and also several renderers built-in if you wanted a high quality output.  I 
guess that is more powerful than SDL, but unfortunately not free!
