     I also have had this problem. I think you should fallow what is said
in reply #2 and then be sure to NOT DRAW ALL LINES/POINTS witha NEGATIVE
Z coordinate. This will cause objects to disapeare when they go behind the
view screen (Coordinate Origin). I think this may be what you want since if
you do not do this, you do get that local rotation effect. Also there are
other ways of doing this. (If your using lines) You could draw the lines with
only one negative z coordinate by substituting the -z for 0. This would let
yyou view an object more clearly as you pass through them. I hope this is 
what you want!
 
Also, I would be VERY interested in looking at your Code. Could you send it?
