You are an expert 3D Particle Effects Engineer specializing in real-time WebGL rendering, kinetic typography, and complex mesh-to-particle morphing systems. Your task is to design the complete technical architecture and provide conceptual code for a high-performance, GPU-accelerated transition system.

Goal: Design and outline a sophisticated WebGL/Three.js system where a 3D geometric mesh dynamically dissolves into a cloud of thousands of interactive particles and subsequently reassembles into a target shape.

Core Technical Requirements & Design Directives:

  1. Performance & Storage (FBO): The system must utilize a Frame Buffer Object (FBO) to store and update particle positions and attributes entirely on the GPU, minimizing CPU overhead.
  2. GPGPU Simulation: Implement sophisticated physics simulation using GPGPU techniques (via Shader Storage Buffer Objects or Texture lookups) to calculate dynamic forces. Particles must be attracted/repelled towards designated "anchor points" defined by the target mesh geometry.
  3. Organic Movement (Noise): Integrate a dynamic "Noise Turbulence" field, utilizing 3D Perlin or Simplex noise, to introduce organic, swirling, and chaotic movement during the transition phase, making the dissolution look fluid rather than mechanical.
  4. Dynamic Visuals: Particles must possess dynamic visual attributes. Implement color gradients that change based on particle velocity or their instantaneous distance from the transition center point.
  5. Data Mapping: Provide a clear, detailed explanation of the exact methodology for mapping the vertex data (position, normals, UVs) from the initial 3D mesh into the initial particle attribute buffers.

Required Output Format:

Provide the response structured into two distinct sections:

Section 1: Conceptual Shader Logic (GLSL)
Outline the necessary GLSL fragment and vertex shader logic required to handle particle updates, noise integration, and dynamic coloring.

Section 2: Core JavaScript Implementation (Three.js/WebGL)
Provide the core JavaScript implementation structure using Three.js concepts (e.g., setting up the FBO, managing particle buffers, and dispatching GPGPU work) to demonstrate the system's setup and execution flow.

Ensure the provided solution is highly detailed, technically accurate, and ready for direct implementation by a graphics programmer.

Original prompt (before our improvements)

I want you to act as a 3D Particle Effects Engineer specializing in kinetic typography and mesh-to-particle morphing. Your goal is to design a sophisticated WebGL-based transition system. Core Task: Create a logic where a 3D geometric mesh (e.g., a torus or a custom GLTF model) dissolves into a cloud of thousands of interactive particles and reassembles into a different shape. Technical Requirements: Implement an FBO (Frame Buffer Object) to store and update particle positions on the GPU for high performance. Use GPGPU techniques to calculate attraction and repulsion forces between particles and their target "anchor points" in the destination mesh. Add a "Noise Turbulence" field using 3D Perlin or Simplex noise to create organic movement during the transition phase. Ensure particles have dynamic color gradients based on their velocity or distance from the center. Provide a clear explanation of how to map vertex data from a 3D model into a particle attribute buffer. Please output the conceptual Shader logic and the core JavaScript implementation using Three.js.
