WebGPU API Demo

Demo

This demo renders a rotating 3D cube by linking JavaScript directly to your GPU. It uploads geometry and WGSL shaders to the video card, then runs a high-speed loop to calculate rotation and redraw the cube with accurate depth perception in real-time. You can see the full code of the demo below.

WebGPU vs WebGL

This demo highlights WebGPU's modern, close-to-metal approach to graphics, which is far more efficient than older standards like WebGL. By defining the entire rendering pipeline upfront, the page tells the GPU exactly how to handle data before drawing begins, reducing the translation work required by the browser and CPU. This lowers overhead, frees the main processor, and enables smoother performance and more complex 3D scenes directly in the browser.

Browser support

The WebGPU API is supported on most modern browsers, including Chromium-based browsers version 113 and above on Windows, macOS, and ChromeOS, Chrome version 121 and above on Android, and Safari on iOS 26 and above.

Use cases

• Rendering complex 3D graphics and games directly in the browser.
• High-performance scientific and data visualization.
• GPU-accelerated image and video processing.
• Machine learning and neural network computations on the client side.
• Real-time simulations and physics calculations.
• Custom shader effects and procedural graphics generation.
