Sports equipment based motion deformation

Abstract

We propose a novel scheme for generating the locomotion of sports equipment along with motion deformation. To accomplish this, we search the event frames in order to find the points where the character is in contact with the sports equipment (contact points) or not (split points). To find these points, it is necessary to locate the corresponding event points in the signal using Discrete Fourier Transformation. This technique generates a left and right hand-cross analysis and sports equipment locomotion adapted to the character motion. Also, the locomotion of the sports equipment is changed by adjusting its properties, and this may require the posture of the character to be modified. In conclusion, we are able to deform the motion of both the sports equipment and the character simply by adjusting the properties of the sports equipment. Our scheme can be used for the motion deformation of any character with an associated sports equipment. © Springer-Verlag Berlin Heidelberg 2005.
