Procedural Marine Landscape Synthesis for Swimming Exergame in Virtual Reality

In this paper, we propose a simulation-based proce-dural modeling approach to automatically synthesize immersive marine landscapes for swimming exergame in virtual reality. Given arbitrary terrain as input, we transform it into a realistic marine landscape according to a novel simulation-based procedu-ral modeling approach inspired by the geological phenomenon of tectonics. During the tectonic simulation, we apply another constraint that is specifying the water area so as to make the top-down view of our synthesized marine landscape match the shape expected from users. Besides, we apply physics rules to the VR controllers to immersively simulate players' swimming experiences in virtual reality and collected feedback from the players who virtually swam in our synthesized marine landscapes.
