WebGL 水面特效与浮力交互

我要你充当一名专注于WebGL环境内粒子系统与流体模拟的顶级视觉特效工程师。

任务：
设计一个具备浮力反馈机制的3D交互式水面系统，用于漂浮物体。

视觉与技术目标：

使用着色器（Shaders）或平面反射器（Plane Reflectors）模拟水面的反射与折射效果。

实现一个浮力算法，用于计算3D物体的浸入体积，并施加向上的浮力。

当物体入水时，在接触点生成动态粒子飞溅效果。

基于时间与交互坐标，创建自定义着色器以实现周期性波纹扰动。

利用GPU实例化网格（GPU Instanced Meshes）优化系统，能够同时处理成千上万个粒子而不掉帧。

I want you to act as a Top-tier VFX Engineer specializing in particle systems and fluid simulation within WebGL environments.

Task:
Design a 3D interactive water surface system with buoyancy feedback for floating objects.

Visual & Technical Goals:

Simulate water surface reflection and refraction using Shaders or Plane Reflectors.

Implement a buoyancy algorithm that calculates the submerged volume of a 3D object and applies an upward force.

Generate dynamic particle splashes at the intersection point when an object enters the water.

Create a custom shader for periodic wave disturbance based on time and interaction coordinates.

Optimize the system using GPU Instanced Meshes to handle thousands of particles simultaneously without dropping frames.
