Spline Overview
Spline is a 3D design tool for Windows and macOS (and web) that makes creating and animating 3D content approachable for designers, without the steep learning curve of traditional 3D software. It offers an intuitive editor for modeling simple 3D scenes, applying materials and lighting, adding animations and interactions, and even building interactive 3D experiences that respond to clicks and hovers. Designers use it for 3D illustrations, web graphics, product mockups, and interactive elements that can be embedded on websites. It supports real-time collaboration and export to images, video, and interactive web code. It uses a freemium model. The full offline editor installs without an internet connection, though collaboration syncs online. It supports physics, particles, and a library of materials and objects, and can embed exports directly into popular website builders.
