I was watching The Simpsons (my favorite animated series) and I started wondering how they animate so smoothly. I tried Google, but I couldn't quite phrase the question right to get what I was looking for, so I figured I'd ask the denizens of TBBS, of whom there are members that have hobbies and occupations as animators. How do they animate so many cells and keep everything so smooth? The lines stay still from one frame to the next. How do animators keep everything so steady? If I tried to do the same, my images would look completely different each time, and they would never gel enough to appear as smooth and realistic. Your answers are appreciated. J.
