我们介绍了一个简单的屏幕空间过滤技术的实时渲染的粒子为基础的流体模拟。从直接从粒子数据生成的深度图开始，我们的新滤波器公式通过考虑窄范围内的深度值来平滑深度图。超出此范围的深度值将被小心处理，以在不连续处附近获得所需的表面形状。我们的配方的简单性导致计算效率的过滤器。我们提出了复杂的基于粒子的流体模拟的例子，并提供比较，清楚地表明，我们的过滤器提供了改进的表面质量方面的表面平滑度和保留边界附近的不连续性，相比以前的过滤方法。
We introduce a simple screen-space filtering technique for real-time rendering of particle-based fluid simulations. Starting with a depth-map generated directly from the particle data, our new filter formulation smooths the depth-map by considering the depth values in a narrow range. The depth values outside of this range are carefully handled to achieve the desired surface shape near discontinuities. The simplicity of our formulation leads to a computationally efficient filter. We present examples with complex particle-based fluid simulations and provide comparisons, clearly showing that our filter provides improved surface quality in terms of surface smoothness and preserving boundaries near discontinuities, as compared to prior filtering methods.
