There aren't any C 3D engines out there.  Well, I found*one* engine, 
http://www.openrm.org/docs/OpenRM-general-FAQ.shtml#cplusplus in a few 
years of searching, but I wouldn't want to use it.  A lot of their 
website hasn't changed since 2005.  Their user mailing list never had 
many posts, and nobody has posted since 2005.  Finally, it's not game 
oriented.  Using an extant 3D engine for game development means getting 
your hands dirty with C++ in any practical industrial sense.  Well, 
unless you go for Java or C#, but that's not relevant to Chicken.

I don't have a pressing need for a security solution.  I'm just fishing 
in the dark for how Chicken could be a value add over the straight Ogre 
engine.  "Eeew, it's C++" isn't part of my thinking anymore.  That kind 
of thinking has made me irrelevant to the game industry.  I've decided 
that industrial considerations, i.e. the size of a community, the 
maturity of the project, what's already done, what's documented and 
tutorialized, are more important than ideologies of perfect programming 
languages.  I think Chicken has to interface to C++ to be of any value 
to the game industry.  It's naive to think that "from scratch" in 
Chicken Scheme will have any impact on the industry at all.
