A browser-based graphics technology that allows developers to render interactive 2D and 3D graphics directly within a web page without plugins. Built on top of OpenGL ES, it exposes a low-level JavaScript API that communicates with the device’s GPU, enabling sophisticated visual experiences—such as real-time animations, immersive data visualizations, and game environments—to run smoothly inside the browser.
WebGL transformed the web from a document-centric medium into a capable graphics platform by giving developers direct access to hardware-accelerated rendering. Because it operates inside the browser’s security sandbox, it offers GPU power while maintaining tight control over memory and execution. Developers write shaders using GLSL (OpenGL Shading Language) to control how graphics are drawn, and browsers handle the rest through standardized APIs.
Today, WebGL is widely used across creative technology, simulation, scientific visualization, e-commerce product viewers, virtual and augmented reality prototypes, and interactive storytelling. Its successor, WebGPU, is emerging with more advanced features, but WebGL remains a backbone of modern interactive web graphics due to its cross-platform support and mature ecosystem.
