Wave J2 · GPGPU grain bed · click-animation bake-off · THROWAWAY PROTO — 2026-06-21
Five panels share an identical dense GPGPU grain bed (96×96 = 9 216 grains, ortho camera). Each panel runs a different click force-model. Auto-fires every 2.4–3.4 s (staggered). Click the sand to trigger manually. Toggle light/dark top-right.
Panel 0 · Mode 0
Strong upward impulse at impact point, slight outward scatter. Grains arc up then fall back under gravity and spring.
Panel 1 · Mode 1
Radial outward push along the bed plane with a slight upward component. Grains slump outward leaving a crater-like hollow.
Panel 2 · Mode 2
Radial wave pulse: sinusoidal ring that expands outward and decays. Produces a spreading ripple through the grain bed.
Panel 3 · Mode 3
Tangential (perpendicular) force rotates grains around the click point. Mild inward pull creates a counter-clockwise / clockwise sandstorm.
Panel 4 · Mode 4
Uniform directional push in a random wind direction each click. Sweeps the affected zone across the bed like a gust of wind.
