WebGL

WebGL is a JavaScript API for rendering interactive 3D graphics within any compatible web browser without the use of plug-ins. WebGL apps consist of a control code written in JavaScript and special effects code that is executed on a computer's GPU. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background.

WebGL Browser Report checks WebGL support in your web browser, produce WebGL Device Fingerprinting, and shows the other WebGL and GPU capabilities more or less related web browser identity.
