What it does

Spline is a browser-based editor for interactive 3D scenes. Objects, materials, lighting, and interaction states can become part of a website or app experience.

When to use it

A product or concept benefits from a spatial demonstration that a flat image cannot explain as clearly.

What you need: A Spline account and a browser that can run the editor.

Try a small build

A suggested exercise to help you evaluate the resource.

Create a scene with one object, a simple material, and a readable camera angle.
Add one interaction, such as changing an object's state on pointer input. Keep the action easy to understand.
Explore the publishing options and test the result on a phone. Provide a useful static alternative in the surrounding page.

You should end up with: A small interactive scene with one clear purpose.

Keep in mind

3D assets can affect loading and rendering performance. Test the actual embedded result rather than judging only inside the editor.
