GPUDevice: createPipelineLayout() method - Web APIs

Limited availability

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

Note: This feature is available in Web Workers.

The createPipelineLayout() method of the GPUDevice interface creates a GPUPipelineLayout that defines the GPUBindGroupLayouts used by a pipeline. GPUBindGroups used with the pipeline during command encoding must have compatible GPUBindGroupLayouts.

createPipelineLayout(descriptor)

descriptor

An object containing the following properties:

bindGroupLayouts

An array of GPUBindGroupLayout objects (which are in turn created via calls to GPUDevice.createBindGroupLayout()). Each one corresponds to a @group attribute in the shader code contained in the GPUShaderModule used in a related pipeline.

label Optional

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

A GPUPipelineLayout object instance.

The following criteria must be met when calling createPipelineLayout(), otherwise a GPUValidationError is generated and an invalid GPUPipelineLayout object is returned:

• The GPUBindGroupLayout objects in bindGroupLayouts are valid.
• The number of GPUBindGroupLayout objects in bindGroupLayouts is less than the GPUDevice's maxBindGroups limit.

Note: The WebGPU samples feature many more examples.

The following snippet:

• Creates a GPUBindGroupLayout that describes a binding with a buffer, a texture, and a sampler.
• Creates a GPUPipelineLayout based on the GPUBindGroupLayout.

// …

const bindGroupLayout = device.createBindGroupLayout({
  entries: [
    {
      binding: 0,
      visibility: GPUShaderStage.VERTEX | GPUShaderStage.FRAGMENT,
      buffer: {},
    },
    {
      binding: 1,
      visibility: GPUShaderStage.FRAGMENT,
      texture: {},
    },
    {
      binding: 2,
      visibility: GPUShaderStage.FRAGMENT,
      sampler: {},
    },
  ],
});

const pipelineLayout = device.createPipelineLayout({
  bindGroupLayouts: [bindGroupLayout],
});
