Just feeling for the limits of what I can do given the contraints of the language. I like to think about things like using the center of the earth as an origin, and using a spherical coordinate system to locate points(and/or areas volumes) on the surface or in space. The accuracy depends mostly on the accuracy of the angles in radians( ie. the number of decimal places of PI). I'm sure it can go into the other direction also, what about nano-technology where you are dealing with the super-small. The ability to distinquish very small angles would be very important. zentara -- I'm not really a human, but I play one on earth. http://zentara.net/japh.html _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
