3D and animation for websites within a page weight budget
3D and animation for websites is a direction of 3D and motion design at Best Boost Partners: a 3D or animated scene for the first screen, animation on scroll, animated icons and illustrations, hover and loading states. The service suits site owners who want movement on the page without losing loading speed. The same studio does SEO, so every scene is designed within a weight budget, with lazy loading and a static fallback image. You receive files in Lottie (JSON), WebM, MP4 or GLB / glTF, ready for the page.
What do we do in 3D and animation for a website?
A scene for the first screen
A 3D or animated scene is designed together with the heading and the button of the first screen. The first frame is prepared as a light static image, so the visitor sees the screen before the scene has loaded.
Animation on scroll
Blocks, illustrations and figures appear or change as the visitor scrolls the page. The animation supports the order of reading and does not hold the text back.
Animated icons and illustrations
Icons and illustrations are animated as vector graphics and exported to Lottie (JSON). A file of this kind stays sharp at any size and usually weighs less than video.
Hover and loading states
Buttons, cards and menus receive states for hover, press and loading. The states are described in a table with durations and motion curves, so that the developer reproduces them exactly.
A weight budget and lazy loading
Before the work starts we set a limit on the weight of the scene files. Scenes below the first screen load only when the visitor comes close to them while scrolling.
A fallback for weak devices
On weak devices and for visitors who have turned on reduced motion in their system, the page shows a static image in place of the scene. The content of the page stays the same.
What do you get from 3D and animation for a website?
- Animation files in the agreed formats: Lottie (JSON), WebM or MP4 video, GIF, image sequences, GLB or glTF models.
- A static fallback image for every scene, for weak devices and for visitors with reduced motion turned on.
- A description of states and triggers for the developer: what starts each animation, how long it lasts and when it loads.
- A record of the file weight of every scene against the agreed budget.
- Source project files, when their handover is fixed in the contract.
When does a website need 3D and animation?
- The first screen of the site looks like a template, and you need a scene that shows the product or the idea of the brand.
- The current animation on the site lowers loading speed, and Core Web Vitals in Google Search Console have become worse.
- A new site is being designed, and the movement is best planned together with the layout.
- Icons and illustrations on the site are static, and the interface does not respond to hover or loading.
Frequently asked questions
Will 3D or animation slow my website down?
Any 3D scene or animation adds weight to a page, and a heavy scene does cost loading speed. The scene is therefore designed within a weight budget, loads lazily and has a static fallback image. Best Boost Partners also does SEO, so the effect of the scene on Core Web Vitals is checked before publication.
What will visitors with old phones or with animation turned off see?
Visitors with weak devices and visitors who have turned on reduced motion in their system see a static image in place of the scene. The text, the buttons and the structure of the page stay the same. The fallback image is prepared together with the scene and is part of the files you receive.
Which format is better for animation on a site: Lottie, video or a 3D model?
The format follows the task. Lottie (JSON) suits vector icons and illustrations, WebM or MP4 video suits complex scenes with light and texture, and a GLB / glTF model suits objects that the visitor rotates. We name the format at the brief stage and explain how it will affect the weight of the page.
