我们提出了一种可视化技术模拟流体动力学数据，可视化的速度场的梯度在一个直观的方式。我们的工作受到流变颗粒的启发，流变颗粒是小而扁平的颗粒，当悬浮在流体中时，它们会与流体的剪切力对齐。我们采用了真实的流变粒子的物理原理，并将其以模型的形式应用于三维速度场。通过模拟这些粒子的行为和反射率，我们能够以一种洞察系统动态的方式渲染3D模拟。结果可以在真实的时间内呈现，允许用户从所有角度检查模拟。我们通过在GPU上结合预计算和快速光线跟踪来实现这一点。我们在几个不同的模拟上展示了我们的方法，显示了他们在这个过程中的复杂动态。
We present a visualization technique for simulated fluid dynamics data that visualizes the gradient of the velocity field in an intuitive way. Our work is inspired by rheoscopic particles, which are small, flat particles that, when suspended in fluid, align themselves with the shear of the flow. We adopt the physical principles of real rheoscopic particles and apply them, in model form, to 3D velocity fields. By simulating the behavior and reflectance of these particles, we are able to render 3D simulations in a way that gives insight into the dynamics of the system. The results can be rendered in real time, allowing the user to inspect the simulation from all perspectives. We achieve this by a combination of precomputations and fast ray tracing on the GPU. We demonstrate our method on several different simulations, showing their complex dynamics in the process.
