GPURenderPipeline

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The GPURenderPipeline interface of the WebGPU API represents a pipeline that controls the vertex and fragment shader stages and can be used in a GPURenderPassEncoder or GPURenderBundleEncoder.

A GPURenderPipeline object instance can be created using the GPUDevice.createRenderPipeline() or GPUDevice.createRenderPipelineAsync() methods.

Instance properties

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

Instance methods

getBindGroupLayout() Experimental: Returns the pipeline's GPUBindGroupLayout object with the given index (i.e. included in the originating GPUDevice.createRenderPipeline() or GPUDevice.createRenderPipelineAsync() call's pipeline layout).

Examples

Note: The WebGPU samples feature many more examples.

Basic example

Our basic render demo provides a simple example of the construction of a valid render pipeline descriptor object, which is then used to create a GPURenderPipeline via a createRenderPipeline() call.

      {
