Abstract
The swimming motion of the virtually evolved creature model proposed by Karl Sims is re-investigated on the basis of hydrodynamics. In his work, physical simulation was performed, and the swimming motion of the evolved creature was presented. Animation of the creatures was stimulus, however, detailed description about the simulation condition and its results were not always well described. In this work, we perform hydrodynamic simulation to investigate the swimming motion of virtual creatures. As a result, it is found that collaborating motion of fluid is essential and indispensable for the motion of the creature in water. This mechanism also works as a constraint in constructing creature’s body. We found that the physical property of the water strictly regulate the structure of swimming creatures.
