Build a Three.js scene with six torus meshes sharing one center. Give successive rings smaller radii and slightly different rotation speeds; animate a subtle emissive accent without postprocessing. Keep a fixed camera looking through the opening.
Build and check.
- Confirm the supplied content, target environment, and required assets before implementing.
- Build a Three.js scene with six torus meshes sharing one center. Give successive rings smaller radii and slightly different rotation speeds; animate a subtle emissive accent without postprocessing. Keep a fixed camera looking through the opening.
- Expose seek(t) so frames can be inspected deterministically; add play, pause, replay, and a reduced-motion still.
- Inspect the opening, midpoint, and final state at desktop and mobile sizes; report any dependency or output limitation.
Know the limits.
- Avoid flashing emission and excessive bloom. Dispose all meshes and stop the frame loop when hidden.
- The prompt guides a coding agent; output quality depends on its implementation and review.
