Fluid Simulation by Particle Level Set Method with an Efficient Dynamic Array Implementation on Gpu

We propose an efficient method to treat dynamic array data on Graphics Processing Unit (GPU), which is applicable to fluid simulations. Few numbers of dynamic structures have been realized on GPU since most of the previous methods store the data in texture to represent the structure and it is difficult to manage the dynamic structure on the texture. Our method uses vertex buffer object for representing the data structure and combines the transform feedback and the geometry program, which are the functionalities of GPU. Our method offers a simple but an efficient way of realizing dynamic array on GPU. Furthermore we apply our method to the implementation of a particle level set method. The particles data are represented by our dynamic array and they are updated, added, and deleted completely on GPU. By using the method, a fast and accurate fluid simulation can be realized.
