Spline is a 3D browser-based modeling tool that allows for collaborative editing. The product has embeds available for web, Android, and iOs (including VisionOS)
The app itself is similar to other design tools, such as Figma and Adobe suite, using similar parameters for sizing, tools, and animations.
What you'll need:
a 3D model downloaded (likely .obj, stl)
A texture map for this object (usually comes with the download on Sketchfab if it has one)
A Spline account
Setup steps
Create an empty Spline design file
Go to Menu>Import>3D Model
Max import size is 60mb
Resize and position the object so it is within your camera viewport (most models seem to import in really large, so you'll likely need to resize)
With the model selected, the Material tab on the right and change to Image type, then upload image.
What's possible:
Has a state manager to define multiple states, then can animate in between them.
Can use similar language to css/js to define interactions
