Convincing and visually pleasing rendering of rain effects enhances the realism of outdoor scenes in many applications. In this paper we described a comprehensive system for interactive rendering of rain effects in real-time in complex environments.
We presented a number of novel effects such as the image-space rainfall rendering, GPU-based water simulation for dynamic puddle rendering, water droplet animation and rendering using graphics hardware and view-dependent wet reflections, amongst all. All of the these effects help us generate an extensive, detail-rich urban environment in stormy weather. We hope that the new technology can be successfully used in the next generation of computer games and real-time rendering.
Truly a team effort of which we are all very proud of.
