Outline of Final Research Achievements

To obtain the realistic images in Computer Graphics, the animation is created by using physics-based simulation. However, from the video creater point of view, such simulations are not always easy to use, since the repetition of adjustments of physical parameters and re-simulations is required. This is one of reasons why a video production takes huge time. In this research, we developed an efficient flow control method based on procedural approach to a physics-based imcompressible fluid simulation. By this research, we showed that our method enables high controllability of fluid simulation and can create more realistic images at the same time. We also showed that our computational cost is not so high.
