WebGL

What is WebGL?

WebGL is a web technology that lets web browsers handle 3D graphics without plugins. Instead of relying on extra software, the browser itself takes care of showing models, games, or charts. With WebGL, people can run interactive 3D scenes right inside a page. It follows the OpenGL ES standard and works as a graphics API through JavaScript, giving web applications the ability to mix smooth visuals with normal web content.

How Does WebGL Work?

When a page loads WebGL, the browser talks directly to the GPU. Developers just use JavaScript here: they write small shader programs that tell the hardware how to draw shapes, apply light, and paint textures. The result is 3D content that updates frame by frame, like a game or a live simulation. Because WebGL works so close to the graphics card, it gives strong performance for projects where speed really matters.

WebGL Context

A project begins by creating a WebGL context on a canvas. That context is the bridge between code and GPU, deciding how 3D rendering happens. Some projects need one context, others two; each manages calls from the graphics library so that applications can keep running smoothly and without glitches.

Examples

• Simple browser games that run in tabs.
  
• Education apps showing 3D content.
  
• Product viewers built on a WebGL context.
  
• Dashboards mixing web content with models.
