GPURenderBundleEncoder: finish() method

The finish() method of the GPURenderBundleEncoder interface completes recording of the current render bundle command sequence, returning a GPURenderBundle object that can be passed into a GPURenderPassEncoder.executeBundles() call to execute those commands in a specific render pass.

Syntax

finish(descriptor)

Parameters

descriptor Optional

An object containing the following properties:

label Optional

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

Return value

A GPURenderBundle object instance.

Validation

The following criteria must be met when calling finish(), otherwise a GPUValidationError is generated and the GPURenderBundleEncoder becomes invalid:

• The GPURenderBundleEncoder is open (i.e., not already ended via a finish() call).
• The debug stack for the current render pass is empty (i.e., no render pass debug group is currently open, as opened by pushDebugGroup()).

Examples

const renderBundleEncoder = device.createRenderBundleEncoder({
  colorFormats: [presentationFormat],
});
recordRenderPass(renderBundleEncoder);
const renderBundle = renderBundleEncoder.finish();

The above snippet is taken from the WebGPU Samples Animometer example.
