How to Add 3D Scroll Animation to Your Site with Dora AI
Dora AI ties 3D assets to scroll position, so a model rotates, the camera pushes in, and text animates as the visitor moves down the page. You enable it per section in the canvas editor and tune the timing curve, not the shader code.
Why Scroll Animation Beats Autoplay Video?
A looping hero video plays whether or not the visitor is interested. Scroll-driven 3D only moves when they do, which mirrors user intent and keeps attention. It also lets a single scene tell a story across several copy beats instead of cramming everything into a silent loop.
The cost is performance. Every scroll frame is a render, so a heavy scene taxes mobile far more than a video.
How Do You Set Up a Scroll Trigger?
- Select the section holding your 3D asset.
- Open the animation panel and choose the scroll-based trigger.
- Define start and end states — for example a 0° to 180° rotation.
- Set the easing so motion starts slow and settles, rather than snapping.
Bind each state change to a copy block so the words and the motion advance together. Mismatched timing reads as a bug even when nothing is broken.
How Do You Keep Mobile Performance Acceptable?
| Lever | Effect |
|---|---|
| Lower poly count | Biggest win on phones |
| 1K instead of 4K textures | Cuts weight sharply |
| Fewer simultaneous animations | Reduces per-frame cost |
| Disable motion on small screens | Guarantees usable mobile |
A pragmatic rule: if a mid-range Android drops below 30fps, cut one asset. Many Dora pages ship a static fallback for mobile and reserve the full 3D experience for desktop, which is a fair trade.
How Much Motion Is Too Much?
One hero scene plus one supporting animation is plenty for a landing page. Pages that animate every section feel jittery and slow, and visitors stop scrolling to let things settle. Aim for two or three motion moments tied to the strongest copy.
Also respect reduced-motion settings. Some visitors get motion sickness, and honouring the OS preference is a basic courtesy that Dora’s settings let you support.
How Do You Review Before Launch?
Test on a real iPhone and a mid-range Android, not just a desktop browser at 50% zoom. Scroll slowly and check the timing, then scroll fast and check for jank. Finally, load on a throttled connection to see how long the 3D takes to appear — a blank hero for three seconds loses people.
Quick Summary
- Dora AI binds 3D assets to scroll position per section, tuned in the canvas editor.
- Pair each state change with a copy block for coherent timing.
- Lower poly counts and 1K textures are the biggest mobile wins.
- Use two or three motion moments, not one per section.
- Always test on real phones and honour reduced-motion preferences.
