[Fluxus] libode internal error 2

[evan.raskob [lists]]

no, I see - by default, libode is double-precision on OS X.  you  
can't just use the compiler flag to switch it to use single-precision.

this is actually a pain, but fixable - all bounding boxes and physics  
functions will need to use doubles instead of floats.  I started  
doing this, but I'm not exactly sure of all implications, because the  
physics bounding box relies on the Primitive->GetBoundingBox() function.

I might try it out and see...

cheers
