What it is

Spline is a browser-based 3D design tool for interactive web scenes, and its AI 3D Generation turns text, an image or both into a model you can drop straight into a scene. You pick from image previews first, then choose an engine such as Hunyuan3D, Hunyuan 3.1 Pro, Trellis 2 or Meshy.

What the AI does
