WebGL Fluid Simulation (Pinned Copy)

This repository now runs a pinned copy of PavelDoGreat/WebGL-Fluid-Simulation, based on commit:

• a2d292931f19d9b3b9f564e23e6c32729d2121c3

The runtime is app-only (no library API). It uses the original simulation logic and the original dat.GUI control set.

What Is Included

• script.js from upstream (with only minimal removals listed below)
• dat.gui.min.js from upstream
• LDR_LLL1_0.png from upstream
• assets/paper-sample-0018.webp (Paper sample image for halftone comparisons)
• Fullscreen canvas entrypoint (index.html)

Intentional Removals From Upstream

• Promo popup and related assets/handlers
• External social/app buttons in GUI
• Google Analytics snippets and ga(...) calls

These removals do not change fluid simulation parameters, solver flow, keyboard controls, or GUI fluid settings.

Controls

• P: toggle pause (PAUSED)
• Space: random splats
• GUI controls include:
  • DYE_RESOLUTION, SIM_RESOLUTION
  • DENSITY_DISSIPATION, VELOCITY_DISSIPATION, PRESSURE, CURL, SPLAT_RADIUS
  • SHADING, COLORFUL, PAUSED
  • Bloom folder (BLOOM, BLOOM_INTENSITY, BLOOM_THRESHOLD)
  • Sunrays folder (SUNRAYS, SUNRAYS_WEIGHT)
  • Halftone folder:
    • enabled
    • source (fluid, sample)
    • preset (Custom, Default, LED screen, Mosaic, Round and square)
    • colorBack, colorFront
    • originalColors, type, inverted, grid
    • size, radius, contrast
    • grainMixer, grainOverlay, grainSize
    • scale, fit
    • legacy aliases (HALFTONE_*) still map to new keys for backward compatibility
  • ASCII folder:
    • enabled
    • mode (mono, color)
    • depth (2..16)
    • chars, inverted, size
    • foreground, background
  • Capture folder (BACK_COLOR, TRANSPARENT, screenshot)

ASCII and Halftone are mutually exclusive: enabling one disables the other. Capture keeps exporting the raw fluid render (without ASCII/halftone passes). source=sample uses assets/paper-sample-0018.webp for direct visual comparison with the Paper reference.
