It is notoriously difficult for artists to control liquids while generating plausible animations. We introduce a new liquid control tool that allows users to load, transform, and apply precomputed liquid simulation templates in a scene in order to control a particle‐based simulation. Each template instance generates control forces that drive the global simulated liquid to locally reproduce the templated liquid behavior. Our system is augmented with a variable proportion of temporary particles to help efficiently reproduce the templated liquid density, with fewer requirements on the surrounding environment. The resulting control strategy adds only a small computational overhead, leading to quick visual feedback for resolutions allowing interactive simulation. We demonstrate the robustness and ease of use of our method on various examples in 2D and 3D.

使用动画模板的基于粒子的液体控制

众所周知，艺术家很难在生成合理动画的同时控制液体。我们引入了一种新的液体控制工具，允许用户在场景中加载、转换和应用预先计算的液体模拟模板，以控制基于粒子的模拟。每个模板实例生成控制力，驱动全局模拟液体局部再现模板化液体行为。我们的系统增加了可变比例的临时粒子，以帮助有效地再现模板化液体密度，对周围环境的要求更少。由此产生的控制策略只增加了很小的计算开销，从而为允许交互式模拟的分辨率提供快速的视觉反馈。
