GPUCanvasContext

The GPUCanvasContext interface of the WebGPU API represents the WebGPU rendering context of a <canvas> element, returned via an HTMLCanvasElement.getContext() call with a contextType of "webgpu".

Instance properties

canvas Read only

Returns a reference to the canvas that the context was created from.

Instance methods

configure()

Configures the context to use for rendering with a given GPUDevice and clears the canvas to transparent black.

getConfiguration()

Returns the current configuration set for the context.

getCurrentTexture()

Returns the next GPUTexture to be composited to the document by the canvas context.

unconfigure()

Removes any previously-set context configuration, and destroys any textures produced while the canvas context was configured.

Examples

const canvas = document.querySelector("#gpuCanvas");
const context = canvas.getContext("webgpu");

context.configure({
  device,
  format: navigator.gpu.getPreferredCanvasFormat(),
  alphaMode: "premultiplied",
});
