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. beforeGPUCanvasContext.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);
