- Morphing between two polygonal shapes (even 3-d ones) isn't too bad.
- You just create a mapping between all the vectors (adding new ones
- where necessary), and plot while interpolating.
-
- Morphing between bitmapped images is a major field of research (see
- this year's proceedings from the ACM Computer Graphics conference).
- it usually requires very high-powered computers, and lots of manual
- input by artists trained in the techniques.

- A good point. You never morph in real-time. You generate a stack of
- bitmaps (which may occupy many megabytes of disk space when you're
- done) and display them flip-book style. Otherwise, you'll never get
- enough speed. The usual way professionals do it is to render one
- frame, commit it to video tape, etc. This saves on the disk space,
- but you need special video recorders that can record one frame at a
- time under computer control. They are very expensive.
