WebGL (Web Graphics Library) is a JavaScript API for rendering high-performance interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML elements. This conformance makes it possible for the API to take advantage of hardware graphics acceleration provided by the user's device.
Support for WebGL is present in all modern browsers (see the compatibility tables below); however, the user's device must also have hardware that supports these features.
The WebGL 2 API introduces support for much of the OpenGL ES 3.0 feature set; it's provided through the WebGL2RenderingContext interface.
The element is also used by the Canvas API to do 2D graphics on web pages.

Compatibility notes
In addition to the browser, the GPU itself also needs to support the feature. So, for example, S3 Texture Compression (S3TC) is only available on Tegra-based tablets. Most browsers make the WebGL context available through the webgl context name, but older ones need experimental-webgl as well. In addition, the upcoming WebGL 2 is fully backwards-compatible and will have the context name webgl2.
Enabling WebGL2. As of September 13, 2016 WebGL2 is still an experimental web technology. It is available in both Firefox 48 and Chrome 53. To enable it: In Firefox. Go to about:config. search for webgl2. double click on webgl.enable-prototype-webgl2 until the value is true. restart Firefox.
WebGL 1.0 is based on OpenGL ES 2.0 and provides an API for 3D graphics. [6] It uses the HTML5 canvas element and is accessed using Document Object Model (DOM) interfaces. WebGL 2.0 is based on OpenGL ES 3.0. It guarantees the availability of many optional extensions of WebGL 1.0, and exposes new APIs. [7]
Jul 7, 2023 · WebGL enables web content to use an API based on OpenGL ES 2.0 to perform 2D and 3D rendering in an HTML canvas in browsers that support it without the use of plug-ins. WebGL programs consist of control code written in JavaScript and shader code (GLSL) that is executed on a computer's Graphics Processing Unit (GPU).
Code sample
main();function main() {const canvas = document.querySelector("#glCanvas");const gl = canvas.getContext("webgl");if (gl === null) {...People also ask
