Abstract
The environment greatly influences acquirement of the behavior of an artificial life creature and artifact object. However, the conventional studies have not accurately considered in a model environmental influence. Instead, these influences are analyzed by replacing them into a simple approximation model. This study focuses on the modeling water environmental influence precisely. As a basic research, the water environment is modeled and constructed by taking account in gravity, buoyancy and a water viscosity. Physics engine is employed for a calculation of an object behavior in the water. Simulation results show that the obtained object movement is quite similar to a realistic world one.
