在这篇文章中，我们采用金等。的GPU为基础的方法来解决Navier-Stokes方程和模型的流体演变的图案化过程。在此方法的基础上，我们添加了更灵活的染料注入操作和更多局部可控的图案设计工具。我们基于我们的非耗散求解器的半拉格朗日方法，消除模糊文物，同时保持性能速度。我们实现了这一目标，通过一种新的方式混合约束插值配置文件（CIP）和MacCormack方法，并将其应用到平流问题。利用这种方法，我们可以设计出许多类型的具象图案大理石花纹艺术不可能与以前的方法。一个实时大理石花纹系统，用于创建大理石花纹纹理交互使用现代CPU。该方法将大理石花纹纹理设计过程建模为二维流体动力学问题，并将纹理形成为二维流场中颜色平流的结果。
In this article, we adopt Jin et al.'s GPU-based method to solve the Navier-Stokes equations and model the fluid evolution of the patterning process. Based on this method, we add more flexible dye injection operations and more locally controllable pattern design tools. We based our nondissipative solver on semi-Lagrangian methodology, which eliminates the blur artifacts while keeping the performance speed. We achieve this goal via a new way of mixing the constrained interpolation profile (CIP) and MacCormack methods and applying it to the advection problem. Using this method, we can design many types of figurative pattern marbling arts not possible with previous approaches. A real-time marbling system for creating marbling textures interactively uses a modern CPU. The approach models the marbling texture design process as a 2D fluid-dynamics problem and forms textures as a result of the color advection in the 2D flow fields.
