Abstract:

For the purpose of improving the dynamic simulation effect of the particle system, this paper focuses on studying the dynamic simulation of the fountain flow based on particle system theory. A fountain particle motion model is constructed by applying the physical dynamic principle. The bead particle is structured by using OpenGL “short line” as the basic particle voxel, which performs better in real-time processing compared with other bead particles, such as sphere, cube and square. To avoid the invisibility of partial particles in 3D scene, the technique of the “△” line combination unit is adopted to implement the dynamic simulation of water beads. In order to agglutinate lots of particles to form water beads with different sizes and show the intermittent cylinder shape of the fountain, the fake particle viscosimetry and the blend operation in OpenGL are also adopted, making the fountain flow more realistic. Experiment indicates that the proposed method can effectively improve the reality and real-time performance of the fountain flow.

Key words: particle system, fountain flow, dynamic simulation, fake particle viscosimetry
