GPUCanvasContext: getCurrentTexture() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The getCurrentTexture() method of the GPUCanvasContext interface returns the next GPUTexture to be composited to the document by the canvas context.

Syntax

js
getCurrentTexture()

Parameters

None.

Return value

A GPUTexture object instance.

Exceptions

InvalidStateError DOMException

Thrown if getCurrentTexture() is called on the canvas context before it is configured (i.e. before GPUCanvasContext.configure() has been called).

Examples

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

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

//...
// Later on
const commandEncoder = device.createCommandEncoder();

const renderPassDescriptor = {
  colorAttachments: [
    {
      clearValue: [0, 0, 0, 1], // Opaque black
      loadOp: "clear",
      storeOp: "store",
      view: context.getCurrentTexture().createView(),
    },
  ],
};

const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);
