A hyper-realistic iridescent black oil shader. Real-time WebGL2 fluid sim that responds to mouse speed + drag to carve, watch it shimmer. Drag your cursor across the screen and watch it carve furrows into a surface of iridescent black oil. Fast strokes generate deep, pronounced distortions; slow movements produce subtle, whisper-thin trails. Thin-film interference paints rainbow shimmer inside the disturbed regions while the resting surface stays pitch black. What's inside: A miniature Navier-Stokes fluid solver running on WebGL2 ping-pong frame buffers - Velocity advection, vorticity confinement, 20-iteration Jacobi pressure projection, viscous damping - Mouse-driven splats along the segment between frames so fast motion never gaps - Super-linear force scaling tied to smoothed pointer speed - Iridescent shading: reconstructed normals, Schlick Fresnel, GGX specular, thin-film interference, faked environment reflection, ACES tone map, chromatic aberration, film grain - Half-res sim, full-res render, DPR capped at 2, dt clamped, visibility-aware RAF loop - Graceful fallback when WebGL2 or float textures are unavailable Use it for: - Living hero backgrounds for product launches - Generative art experiments - Studying real-time shader and fluid simulation patterns - A starting point for your own oil / mercury / water / honey variants - Curing boredom on a Saturday night
