APPLICATION OF COMPUTER ANIMATION TECHNIQUES FOR PRESENTING BIOMECHANICAL RESEARCH RESULTS

Computer animation is becoming a widely accepted method for presenting results of biomechanical analyses and simulations. After summarizing the main aspects of three-dimensional and video overlaid animation, tw o applications of these techniques are presented. A parameterized grap hical model of the tennis racket has been developed, which can be used for visualizing the simulated ball-racket impact phase. In the second example, high-speed video sequences of recorded drop jumps are overla id with graphical elements to compare methods for determining the jump ing height and related parameters. These graphical elements represent quantities, which are calculated applying the different methods. Diffe rences can vividly be demonstrated. (C) 1998 Elsevier Science Ltd. All rights reserved.
