Web development doesn't have to be boring boxes and flat layouts. Three.js opens up a dimension of creative expression that sets projects apart.

For Creative Twinkles' agency site, I built an interactive 3D scene that responded to scroll position and mouse movement. The key was keeping it performant:

• Use instanced meshes for repeated geometry
• LOD (Level of Detail) for complex models
• requestAnimationFrame with delta time, not setInterval
• Dispose geometries and materials on unmount

GSAP's ScrollTrigger pairs beautifully with Three.js. Pin the canvas, then animate camera position and material properties based on scroll progress.

The secret sauce: subtle is better. A gentle parallax, a soft glow, a mesh that breathes — these create atmosphere without screaming "look at me."

Tools I use:

• Three.js for 3D rendering
• GSAP + ScrollTrigger for scroll-driven animation
• Leva for debug controls during development
• R3F (React Three Fiber) for React integration
