一、引言近年来计算机三维动画特效领域发展迅猛,在众多模拟对象中,流体以其特有的高自由度和另类审美价值占据了重要位置。大尺度流体模拟、流体混合与相变、流固耦合等复杂运动形式一直都是三维中的挑战性课题。大尺度流体模拟中不仅要展现大尺度流体正确的体量关系,更要实现如泡沫、水雾、飞溅等细节的构建。运用流体动力学模拟软件Realflow下的Hybrido混合式大尺度液体求解系统,使用网格流体与粒子流
I. INTRODUCTION In recent years, the field of computer 3D animation has developed rapidly. Among many simulation objects, fluid occupies an important position with its unique high degree of freedom and alternative aesthetic values. Large-scale fluid simulation, fluid mixing and phase transition, fluid-structure interaction and other complex forms of motion have always been three-dimensional challenges in the project. Large-scale fluid simulation not only to show the correct volume relationship of large-scale fluid, but also to achieve such as foam, water mist, splash and other details of the building. Using the Hybrido hybrid large-scale liquid solution system under the Realflow simulation software Realflow, the mesh fluid and particle flow
