WebGL is a JavaScript API that allows developers to create interactive 3D graphics within web browsers without the need for plugins. It is based on the OpenGL ES standard, which is widely used in mobile and embedded systems. By leveraging the power of the Graphics Processing Unit (GPU), WebGL enables smooth rendering of complex visual scenes directly in web applications. WebGL is supported by most modern web browsers, making it accessible to a wide audience. It is commonly used in various applications, including online games, data visualization, and virtual reality experiences. With WebGL, developers can enhance user engagement by providing rich, immersive graphics directly in the browser.
