GPURenderPassEncoder: pushDebugGroup() method

{{APIRef("WebGPU API")}}{{SecureContext_Header}}{{AvailableInWorkers}}

The pushDebugGroup() method of the {{domxref("GPURenderPassEncoder")}} interface begins a render pass debug group, which is marked with a specified label, and will contain all subsequent encoded commands up until a {{domxref("GPURenderPassEncoder.popDebugGroup", "popDebugGroup()")}} method is invoked.

This could be used for telemetry, or may be utilized in {{domxref("GPUError")}} messages, browser dev tools, or other services in the future to help with debugging.

Syntax

pushDebugGroup(groupLabel)

Parameters

• groupLabel
  • : A string representing the label for the debug group.

Return value

None ({{jsxref("Undefined")}}).

Examples

// …

const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);

passEncoder.pushDebugGroup("my_group_marker"); // Start labeled debug group

passEncoder.setPipeline(renderPipeline);
passEncoder.setVertexBuffer(0, vertexBuffer);
passEncoder.draw(3);

passEncoder.popDebugGroup();

// …
