GPUTexture

The GPUTexture interface of the WebGPU API represents a container used to store 1D, 2D, or 3D arrays of data, such as images, to use in GPU rendering operations.

A GPUTexture object instance is created using the GPUDevice.createTexture() method.

depthOrArrayLayers Experimental Read only

A number representing the depth or layer count of the GPUTexture (pixels, or number of layers).

dimension Experimental Read only

An enumerated value representing the dimension of the set of texels for each GPUTexture subresource.

format Experimental Read only

An enumerated value representing the format of the GPUTexture.

height Experimental Read only

A number representing the height of the GPUTexture in pixels.

label Experimental

A string providing a label that can be used to identify the object, for example in GPUError messages or console warnings.

mipLevelCount Experimental Read only

A number representing the number of mip levels of the GPUTexture.

sampleCount Experimental Read only

A number representing the sample count of the GPUTexture.

usage Experimental Read only

The bitwise flags representing the allowed usages of the GPUTexture.

width Experimental Read only

A number representing the width of the GPUTexture in pixels.

createView() Experimental

Creates a GPUTextureView representing a specific view of the GPUTexture.

destroy() Experimental

Destroys the GPUTexture.

In the WebGPU samples Textured Cube sample, a texture to use on the faces of a cube is created by:

• Loading the image into an HTMLImageElement and creating an image bitmap using createImageBitmap().
• Creating a new GPUTexture using createTexture().
• Copying the image bitmap into the texture using GPUQueue.copyExternalImageToTexture().

//...
let cubeTexture;
{
  const img = document.createElement("img");

  img.src = new URL(
    "../../../assets/img/Di-3d.png",
    import.meta.url,
  ).toString();

  await img.decode();

  const imageBitmap = await createImageBitmap(img);

  cubeTexture = device.createTexture({
    size: [imageBitmap.width, imageBitmap.height, 1],
    format: "rgba8unorm",
    usage:
      GPUTextureUsage.TEXTURE_BINDING |
      GPUTextureUsage.COPY_DST |
      GPUTextureUsage.RENDER_ATTACHMENT,
  });

  device.queue.copyExternalImageToTexture(
    { source: imageBitmap },
    { texture: cubeTexture },
    [imageBitmap.width, imageBitmap.height],
  );
}
//...
