[DC] Foveated Fluid Animation in Virtual Reality
Yue Wang · 2023
Large-scale fluid simulation is often utilized in virtual reality (VR) applications. Physics-based fluid simulation benefits computer graphics with more realistic fluid phenomena, increasing users' immersion in VR. However, the requirements of real-time implementation and the limited computation resources hinder its application in VR. In this article, we first propose foveated fluid animation for applying physics-based fluid simulation in VR. We divide the entire field of view (FOV) into three eccentric circular regions, and fluid particles are scaled into three sizes adaptively in terms of their distributions from the foveal to the peripheral. The proposed method is expected to provide VR applications with large-scale fluid simulation while maintaining high simulation accuracy and minimal computation load. Furthermore, we introduce a novel metric, Fluid Particle Per Degree (FPPD), for optimizing the performance of the proposed method. Both subjective and objective measurements are expected to conduct based on the prototype in the future. We expect the metric to benefit the application of foveated fluid animation with optimal performance in future VR.
