Study of algorithms for interaction between flowing water and complex terrain in virtual environment

Abstract

SPH scheme and GPU-accelerated method are combined to construct particle model of fluid for gaining realistic model of flowing water interacting to complex terrain in virtual environment. Furthermore, coordinate information of particles are accessed and isosurface model of fluid is constructed by combining metaballs model and marching cubes method for rendering of flowing water. Terrain model is constructed based on DEM data. Terrain data are extracted and displayed by boundary particles. Real-time rendering of flowing water interacting to complex terrain in virtual environment is implemented.
