带有漂浮对象的水波模拟

Wave Simulation with a Floating Object

针对实时水波模拟中二维波动方程解法复杂度高、编程求解困难的缺点,基于网格对水面建模,在时间和空间轴上对水波运动离散化处理,并使用数值方法对微分方程近似求解。且为满足场景中水面与物体交互需要,对漂浮对象进行物理建模,通过计算漂浮对象在水中浮力和水波对其推力来模拟水面上的漂浮状态。运行结果表明,该方法可对水波及漂浮物进行实时仿真,模拟速度快,视觉效果好,漂浮效果真实自然。

For the high complexity and programming difficulty in solving 2-dimensional wave equation in real-time wave simulation,a model is bullt based on water face grid,the wave motion is olescreted in time and space axis,and numerical methods are used to solv differential equation.In order to meet the need of the interaction between the surface and the object in the scene,the floating object is modeled by the physical modeling,and the floating state of the object is simulated by calculating the buoyancy and thrust.The results show that the method can simulate the wave and floating object in real time,the simulation speed is fast,the visual result is good,and the floating effect is real and natural.
