> Stardust: lattice shapes made only of luminous glittering dust that flow into one another on a click. A real-time WebGPU experiment by Luis Bizarro.

About 1.6 million fine grains of glittering dust hold to the surface of a celestial shape (Nova, Lantern, Aurora, Halo, Nebula, Cocoon or Orb: gyroid, diamond, Neovius and Lidinoid lattices carved into a star, a cube, a ribbon, a torus and spheres), glinting on their edges while wisps peel off and drift away on curl noise. One key light shapes the form, with a cool fill on the shadow side and a shallow depth of field. A click flies the dust into the next shape in one eased motion that sweeps from left to right: the old form loosens into a swirling cloud and the new one gathers and comes to rest. Dragging turns the shape, which springs back to its pose. Moving the pointer stirs a fluid that carries the dust in eddies before it heals back and lifts glittering dust off the shape where it passes, and the camera drifts toward the pointer. The grains are simulated in compute shaders on signed distance fields baked from analytic triply periodic surfaces and drawn as additive sprites with depth of field.
