- The easiest and most common explanation I have heard is this:
-
- Build an arm, with seprate objects for the upperarm, lower arm (forearm), hand
- (palm) and fingers. Assemble the parts hierachicly (sp), and position the
- parts so that the arm hangs naturally.
-
- Now suppose you wanted the have the finger move up and press a button infront
- of the body, about shoulder level. How would you do it? It would be a pain
- in the ass. With IK, you could grab the finger, rotate it so it points
- straight ahead and drag it up to the button. The other parts of the arm would
- then follow and bend to match the movement in much the same way your own arm
- arm would in the real world.
-
- It's great for doing walking and other character animation, as well as machines
- and such.
