Range of action
The range of action is defined as one extreme position to the final extreme
position. Some animation sequences achieve the illusion of motion by first
illustrating the extremes then, drawing the positions in between the extremes
to complete the range of action. By drawing the extreme positions first, you
can determine the amount of image area the character requires to move and
the characters relationship to other characters and objects in the image.
Figure 4-9 shows extreme positions of the arm.
The drawings in between
the extremes help to smooth and define the range of action.
Figure 4-9.Drawings requires to show a range of action made
by an arm: A. Arm extended; B. Arm contracted.
