You have then arrived at perhapsthe most exciting part of 3-D design, which isanimating a character. Up to now the work has beensomewhat creative, sometimestedious, and often difficult.It is very gratifying when all your previous effortsstart to pay off as you enliven your character. When animating, there is a creative flow that increases graduallyover time.

Thefollowing pointers are meant to give you some direction.Feel free to experiment with them. Bend andbreak the rules whenever you think it will improve theanimation.SOME ANIMATION POINTERS1. Try isolating parts. Sometimes this is referredto as animating in stages. Rather than trying tomove every part of a body at the same time, concentrateon specific areas. Only one section ofthe body is moved for the duration of the animation.Then returning to the beginning of the timeline,another section is animated.
