Dark3

A three.js and GSAP scratch scene: one rotating cube on a full-viewport canvas, with GSAP tweening the page background underneath it.

Open index.html directly, no build step. three.js r128 and GSAP 3.12 load from cdnjs, so the first run needs network.

• index.html - canvas element and the two CDN scripts
• script.js - scene, camera, renderer, and the animation loop
• styles.css - full-bleed canvas, no scrollbars

Resizing the window does not currently update the camera aspect or the renderer size.
