Converting to awt-style coordinates?

Hi,

I was wondering if there was an easy way to flip all the components of a virtual universe from the usual coordinate system (origin at bottom left corner) to the awt-style system (origin at top left with z=0 out of the screen). (0,0) at top left is such a standard for graphics APIs that it seems like there should be an easy way to do this in the case that someone wants to draw in the “traditional” coordinate system. Is there?

Thanks,
DAT
