Abstract
This study verifies a relationship between environment and virtual seaweed to examine twining of seaweed in a cultivation pool. The morphology of virtual seaweed is modeled by L-system. Physics modeling is adopted to realize its physical motion. Two physical properties, adhesiveness, and tear are artificially introduced into this model. A virtual underwater environment is constructed by the Lattice Boltzmann method The virtual seaweed behavior is simulated in the given environment by physics calculation. In order to examine a force by alteration of water flow for the virtual seaweed, the simulation is executed under some water flow patterns. We ascertained that the twining of virtual seaweed has the close relationship with the water flow.
