An exploded technical view on a dark blueprint floor: a hex bolt, two washers, a pair of anodised plates and a nut float apart along a dashed axis, then assemble in order, the nut spinning down the real thread until it seats, before the stack comes apart again.
Run the real thing here, tune it, then copy the prompt that rebuilds it.
The preview is the real three.js scene in a sandboxed frame, not a recording. Everything responds to you.
Swatches recolour, sliders move the parameters that matter, Randomize finds what you would not have typed. Structural changes rebuild the geometry.
Single HTML by default, or a Next.js, React, Vue or Astro component that imports three from npm.
It carries geometry, motion, camera and material intent with your values, in build order.
Geometry, then motion, then camera, then material. Scroll and hover behaviour usually takes a second pass; that is normal.
