Create a real-time fluid simulation on a full-screen canvas where dragging the mouse pushes swirling colored dye through the fluid.

The user wants a real-time fluid simulation on a full-screen canvas with mouse interaction that creates swirling colored dye effects. This needs to be a single HTML file with inline CSS and JavaScript, no external dependencies. I'll create a fluid simulation using a grid-based approach with: 1. A velocity field (u, v components) 2. A dye/density field with RGB colors 3. Mouse interaction that adds velocity and dye 4. Advection to move the fluid 5. Diffusion to spread it (optional, can skip for performance) 6. Projection to ensure incompressibility Let me create a comprehensive fluid simulation with: - Canvas filling the full screen - Mouse drag interaction that adds both velocity and colored dye - Multiple dye colors that cycle or vary - Proper fluid dynamics (advection, diffusion, pressure projection) - Smooth rendering I'll use a simplified Navier-Stokes solver that runs in real-time.
I'll create a real-time fluid simulation with swirling colored dye. Let me build this as a single HTML file.

I've created a complete fluid simulation with: - Full-screen canvas - Grid-based Navier-Stokes fluid solver - RGB color dye system - Mouse/touch interaction that adds velocity and colored dye - Color cycling for rainbow effects - Proper fluid physics: advection, diffusion, pressure projection - Fade effect for visual appeal - No external dependencies The simulation should work well. Let me verify the file was created properly.
I've created a real-time fluid simulation with the following features: **Fluid Physics:** - Grid-based Navier-Stokes solver with velocity field (u, v) and density field - Advection moves fluid and dye through the velocity field - Diffusion spreads the dye slightly - Pressure projection ensures incompressible (swirling) fluid behavior **Interaction:** - Drag mouse (or touch on mobile) to inject colored dye and velocity into the fluid - The dye color cycles through the rainbow as you drag - Mouse movement direction determines the velocity/injection direction - Dye spreads to neighboring cells for smoother effects **Visuals:** - Full-screen canvas that resizes with the window - RGB color channels for vibrant, multi-colored dye - Subtle fade effect creates trailing patterns - Real-time rendering at ~60fps **Technical:** - Self-contained in one HTML file - No external dependencies or network requests - Efficient grid-based simulation (128x128 resolution) - Touch support for mobile devices Open the file in a browser and drag your mouse around to create swirling colored dye patterns!
