3D Course Showcase Website

I need a visually rich 3-dimensional website that spotlights our catalogue of digital courses. The site’s core purpose is a product showcase, so every scene should immediately draw visitors into the learning experience rather than feeling like a typical flat catalogue.

Here is what I’m looking for:

• Immersive 3D interface: Think WebGL or Three.js for fluid, in-browser navigation across course “spaces.”
• Course previews: Each course tile should expand into a quick trailer—short video or animated walkthrough—without forcing a page reload.
• Student testimonials: Layer short, authentic quotes or 30-second video clips into the 3D environment so prospects see social proof as they explore.

Instructor bios are not essential for the first release, but build the back-end flexibly enough that we can drop them in later if we choose.

Design must load fast on desktop and mobile, obey modern accessibility guidelines, and be easy for my non-technical team to update (CMS or a headless setup is fine so long as the workflow stays simple). When you reply, show me links to any interactive 3D work you have shipped along with a brief outline of the tech stack you’d choose and why.
