File Formats: Three JS (JSON)

Three.js is a cross-browser JavaScript library/API used to create and display animated 3D computer graphics in a web browser. Three.js uses WebGL.

Three.js allows the creation of GPU-accelerated 3D animations using the JavaScript language as part of a website without relying on proprietary browser plugins.

LEADTOOLS supports Three.js JSON Geometry format 4 or higher.

You can load any of the Three.js files as either vector images or raster images. Users can load a Three.js(JSON) file and save it to any of the file formats supported by LEADTOOLS.

LEADTOOLS supports loading this format as a raster image, vector image, or SVG (Scalable Vector Graphics) document.

This file format is not supported in the Imaging toolkits. Read support for this format is provided in the Document and Medical Imaging toolkits. For a list of products, refer to the Products Overview.

The default extension used by this format is: JSON.
