Animated Triangle — Webgl Code
Animates a triangle by updating vertex positions every frame.

const canvas = document.getElementById('canvas');
const gl = canvas.getContext('webgl');
// Setup shaders and buffers
// ... setup code ...
let offset = 0;

WebGL (Web Graphics Library) is a low-level JavaScript API for rendering high-performance 2D and 3D graphics in the browser using the GPU. It provides a JavaScript binding to OpenGL ES, allowing hardware-accelerated graphics without plugins.
Primary Use Cases
- ▸3D games and engines in the browser
- ▸3D product configurators (cars, furniture, etc.)
- ▸Scientific and medical visualization
- ▸Architectural & engineering simulations
- ▸GPU-accelerated data visualization dashboards
Notable Features
- ▸GPU-accelerated real-time rendering
- ▸Programmable shader pipeline
- ▸Cross-platform & plug-in free
- ▸Based on OpenGL ES
- ▸Broad browser and hardware support
Origin & Creator
WebGL was developed by the Khronos Group, the same industry consortium behind OpenGL, Vulkan, and WebGPU. The first final specification (WebGL 1.0) was released on March 3, 2011, with precursor work starting around 2006 at Mozilla as a Canvas 3D experiment.
Industrial Note
WebGL is widely used in scientific visualization, CAD tools, GIS mapping, medical imaging, and 3D configurators for industries like automotive and e-commerce.
