Yes:

if(boost::is_floating_point<T>::value)
   return &glVertex2d;
else
   return &glVertex2i;

and the same goes for the other ternary. This has nothing to do with 
boost. The two options in a ternary have to be of the same type. You 
could also cast them, but that would only be shorter with appropriate 
typedefs.
