external texture view

A normal GPUTextureView now satisfies externalTexture bind-group slots. Cache one texture per source frame and reuse the view — cheaper than calling importExternalTexture every frame.

device.createBindGroupLayout—

device.createBindGroup—

resulting layout—

the code

const bgl = device.createBindGroupLayout({
  entries: [{
    binding: 0,
    visibility: GPUShaderStage.FRAGMENT,
    externalTexture: {},
  }],
});

// Pre-136: only an actual external texture allowed.
// 136+: a regular GPUTextureView is accepted too — useful for caching.
const view = myTexture.createView();
const bg = device.createBindGroup({
  layout: bgl,
  entries: [{ binding: 0, resource: view }],
});
