GPUCommandEncoder: finish() method

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

The finish() method of the GPUCommandEncoder interface completes recording of the command sequence encoded on this GPUCommandEncoder, returning a corresponding GPUCommandBuffer.

Syntax

finish()
finish(descriptor)

Parameters

descriptor Optional

An object that can contain the following properties:

label Optional: A string providing a label for the returned GPUCommandBuffer that can be used to identify it, for example in GPUError messages or console warnings.

Return value

A GPUCommandBuffer object instance.

Validation

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

There are no active debug groups (i.e. started via pushDebugGroup()).
The GPUCommandEncoder is in an open state — this means that:
- There are no child GPUComputePassEncoder or GPURenderPassEncoders active that have not been end()ed.
- The GPUCommandEncoder has not already had finish() called on it (in which case it cannot be used to encode any more commands).

Examples

// ...

const commandBuffer = commandEncoder.finish();
device.queue.submit([commandBuffer]);
