TD-Reactive — Audio-Reactive 3D Particle Simulation

Every particle carries position and velocity in GPU ping-pong buffers, integrated with transform feedback each frame: curl turbulence, travelling attractors, local clustering, drag and speed limits. Particles die and respawn, so the scene never repeats — kick drums detonate shockwaves, the core breathes with the bass.

• F.01Up to 10,000,000 GPU particles with perspective camera, orbit and zoom
• F.02Stem roles: kick shockwaves, bass pulse, vocal flow, hat sparks, melody pitch
• F.037 worlds: Nebula, Fluid, Orbital, Growth, Neural, Inferno, Plasma
• F.04Deep shadow map from the light's view, ACES tonemapping, film grain
• F.05Live 64-band spectrum analyzer, file / microphone / procedural demo synth input
• F.06Rust compiled to WebAssembly, zero installs, runs in a browser tab

Drag to orbit, wheel to zoom. Sliders for sensitivity, speed, color, trail, particle size, density (10K–10M), chaos, variation, light, shadow and sharpness.
