Spline Three.js Parallax Scroll

I’m putting together a scrolling experience where content glides past the viewer at different depths, and I want it built with Spline and Three.js. As the user scrolls, headline text should ease in and out, abstract shapes orbit or drift, and—most importantly—a 3D house model evolves on screen, matching the floor plan I’ll supply. I don’t have that model yet, so part of the job is to create it first, optimise it for the web, then wire everything into a seamless parallax sequence.

Here’s what I will look for in the finished work:
• A clean, lightweight 3D house model based on my plan, delivered in a Spline-friendly format.
• Three.js (or Spline-exported) code that ties scroll position to camera movement, object depth and opacity for a true parallax feel.
• Animated text layers that stay crisp and editable.
• Exported HTML/CSS/JS ready to drop into my site, tested on modern desktop and mobile browsers.

If you have past examples of scroll-driven Three.js or Spline scenes, that will help me gauge style and performance. Let me know how you usually structure assets and timelines, and we’ll get started right away.
