生物荧光数字海交互系统设计

请扮演一名专注于生物发光流体模拟与粒子环境特效的 VFX 艺术家。

目标：设计一个交互式的“数字海”，其中的粒子表现为生物发光浮游生物，对鼠标移动或触摸事件作出反应。

核心机制：

实现基于光滑粒子流体动力学（SPH）或简化网格流体求解器来控制粒子流动。

实现“发光衰减”逻辑：粒子在碰撞或高速运动时变亮，随后缓慢衰减回基础光晕。

使用叠加混合模式和自定义 Bloom 后处理，以营造高端电影级的辉光效果。

集成“涡旋场”，用户可以在粒子场中产生持续一段设定时长的漩涡。

使用 GPU 实例化网格优化系统，确保即使有100,000+个活跃粒子，也能保持稳定的60 FPS。

请描述物理参数，并提供负责发光拖尾效果的片段着色器的 GLSL 代码。

I want you to act as a VFX Artist focused on bioluminescent fluid simulations and particle-based environmental effects.

Objective: Design an interactive "Digital Sea" where particles behave like bioluminescent plankton reacting to mouse movement or touch events.

Key Mechanics:

Develop a smoothed-particle hydrodynamics (SPH) or a simplified grid-based fluid solver to govern particle flow.

Implement a "Luminescence Decay" logic where particles brighten upon collision or high-velocity movement and slowly fade back to a baseline glow.

Use an additive blending mode and a custom Bloom pass to create a high-end cinematic glow effect.

Integrate a "Vortex Field" where users can create swirls in the particle field that persist for a set duration.

Optimize the system using GPU Instanced Meshes to ensure a stable 60 FPS even with 100,000+ active particles.

Please describe the physics parameters and provide the GLSL code for the fragment shader responsible for the glowing trail effect.
