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