beginComputePass method

  1. @override
ComputeEncoder beginComputePass({
  1. String? label,
  2. PassTimestampWrites? timestampWrites,
})

Opens a compute pass; label names it to a debugger and to gpuTimings. timestampWrites (since 1.0) names where the pass writes its start and end GPU times — DeviceFeature.timestampQuery.

Implementation

@override
ComputeEncoder beginComputePass({
  String? label,
  PassTimestampWrites? timestampWrites,
}) {
  if (timestampWrites != null) {
    features.require(DeviceFeature.timestampQuery, backend: _backend);
  }
  return WebGpuComputeEncoder(
    _gpuDevice,
    features: features,
    samplerFor: _samplerFor,
    label: label,
    timestampWrites: _timestampWritesOf(timestampWrites),
    limits: limits,
    uniforms: _uniformArena,
  );
}
