Look at GlEnable(GL_POLYGON_SMOOTH) (or GL_POINT_SMOOTH, GL_LINE_SMOOTH).

There's also GlHint(GL_POLYGON_SMOOTH_HINT, ...) and friends whereby you 
can influence how the antialiasing is done.

The result of this may not always be nice enough (as each polygon is 
antialiases "by itself"), then you'll have to look at using the 
accumulation buffer or some such. But I would start with the simple 
GlEnable() call above:-)
