Realistic 3D Animated Educational Website

I need a small yet visually striking site centred on realistic 3D animations that teach users step by step. Every animation must load straight in the browser—no video files—so WebGL with Three.js, Babylon.js or a comparable framework will be essential. I already have the written scripts and rough storyboards; your job is to model, animate and integrate the scenes so visitors can rotate, zoom and play each sequence smoothly on desktop and mobile.

Key deliverables
• Landing page that introduces the first instructional animation without noticeable delay
• Modular sections, each tied to its own 3D sequence and explanatory text
• Responsive layout, intuitive controls and basic SEO tags

Acceptance criteria
• Animations hold 60 fps in current Chrome, Safari and Edge
• Individual scene weight kept under 5 MB
• No external plugins required for interaction

If any part of that scope needs clarification, let me know—otherwise I’m ready to move forward right away.
