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.
Integration with Web Standards
WebGL is fully integrated with other web standards, allowing GPU-accelerated usage of physics, image processing, and effects in the HTML canvas. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background.
Programming Structure
WebGL programs consist of control code written in JavaScript and shader code written in OpenGL ES Shading Language (GLSL ES). The code is executed on a computer's GPU.
Development and Maintenance
WebGL is designed and maintained by the non-profit Khronos Group. On February 9, 2022, Khronos Group announced WebGL 2.0 support from all major browsers.
Applications
Today, WebGL is widely used across creative technology, simulation, scientific visualization, e-commerce product viewers, virtual and augmented reality prototypes, and interactive storytelling.
Future: WebGPU
From 2024, a new graphics API, WebGPU, is being developed to supersede WebGL. 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.
