Sorry, no, but you could use the "shadow volumes" technique to achieve

Hmm,  The shadow drawing code seems pretty short, which is good.  It doesn't run, which makes it hard to port to Python.  I've heard that this particular method is slow though.

I've been on this exact same page, but I was unable to port it.
