The Journal of Visualization and Computer Animation July-September 1995 [antikvár]

THE JOURNAL OF VISUALIZATION AND COMPUTER ANIMATION, VOL. 6: 127 (1995) Editorial In the first paper of this issue, Larry Gritz and James Hahn from The George Washington University present an approach to articulated figure motion in which motion tasks are defined in terms of goals and ratings. They use genetic programming to automatically derive control programs for the agents which achieve the goals. The second paper, by Diane Tang from Harvard University, J. Thomas Ngo from Interval Research Corporation and Joe Marks from Mitsubishi Electric Research Labs, shows how A^-body inverse problems can be formulated as optimization tasks. The method is applied for the inverse problem of motion synthesis in animation. The third paper, by Norishige Chiba, Shinji Sanakanishi, Kenichiro Yokoyama and Isao Ootawara from Iwate University, Kazunobu Muraoka from Morioka Junior College and Nabuji Saito from Tohoku Institute of Technology, all in Japan, presents a new type of particle-based simulation method for complex water currents which is not based on strict fluid dynamics, but rather classified into a 'quasi-physically-based' simulation method constructed on the basis of algorithmic approaches. The last paper, by Leon Fedenczuk and Brian Wyvill from the University of Calgary in Canada, describes the simulation of the movement of oil and gas in porous media. They explain how to simulate the porous medium using a pointer-based octree, representing the pores and the grains. Nadia Magnenat Thalmann Daniel Thalmann © 1995 by John Wiley & Sons, Ltd.
