WebGL is a powerful JavaScript API that enables high-performance 3D and 2D graphics rendering in compatible web browsers without requiring additional plugins. Built on OpenGL ES, it allows developers to create interactive and visually rich applications directly within the browser, leveraging the GPU for accelerated rendering. WebGL is widely used for games, simulations, data visualization, and creative art projects. It integrates seamlessly with HTML5, enabling dynamic content to blend smoothly with web pages. By utilizing shaders and hardware-accelerated rendering, WebGL delivers smooth, responsive graphics. Major browsers like Chrome, Firefox, Safari, and Edge support WebGL, making it a versatile choice for cross-platform development. With frameworks like Three.js and Babylon.js, developers can simplify complex 3D rendering tasks while maintaining performance.
