Real-time Rendering of Point based Water Surface

Abstract

In recent years, attention has been paid to particle based fluid simulation, with several methods being developed to incorporate particle based simulation into CG animations. These methods reconstruct water surfaces that are usually represented by polygons. However, the computational cost of the surface reconstruction is quite high. Therefore, it is difficult to render the result of the particle based simulation at interactive frame rates. To address this, we present a real-time rendering method for particle-based simulation, taking into account optical effects such as reflection, refraction, and caustics. We present an efficient GPU accelerated surface reconstruction method from particles.
