Outline of Final Research Achievements

Numerical simulation is an important technique to predict behaivor of real phenomenon in a computer. In this research, we developed a method to allow surface representation of both smooth and sharp features for liquid simulations which has defined border between liquid and gas. As a result, we archive more high quality visualization for the numerical simulation. Moreover, we solved a problem of non-uniform distribution of particles that will affect quality of the surface.
