The reflection of a bright light source on a dynamic surface such as water with waves can be difficult to render well in real time due to reflection aliasing and flickering. In this paper, we propose a solution to this problem by approximating the reflection direction distribution for the water surface as an elliptical Gaussian distribution. Then we analytically integrate the reflection contribution throughout the rendering interval time. Our method can render in real time an animation of the time integrated reflection of a spherical light source on highly dynamic waves with reduced aliasing and flickering.

时空抗锯齿，用于在水波上渲染反射

由于反射混叠和闪烁，明亮的光源在动态表面（例如水）上的反射可能难以实时呈现。在本文中，我们通过将水表面的反射方向分布近似为椭圆高斯分布来提出该问题的解决方案。然后，我们分析整个渲染间隔时间内的反射贡献。我们的方法可以实时渲染球形光源在高动态波上的时间积分反射动画，并减少了混叠和闪烁。
