| Parameter | Description |
|---|---|
| name | Name of the profile information used for sampling. |
| sampler | The CustomSampler that the CommandBuffer uses for sampling. |
| marker | The ProfilerMarker that the CommandBuffer uses for sampling. |
| contextObject | Object associated with the operation. The Profiler displays this object in the sample hierarchy, allowing you to identify which specific resource the sample was recorded for. |
Adds a command to begin profile sampling.
Schedules a performance profiling sample to begin when the Command Buffer reaches this point. This is useful for measuring CPU and GPU time spent by one or more commands in the Command Buffer.
A profiling sample that starts with BeginSample must always end with a call to CommandBuffer.EndSample with the same argument.
When passing a contextObject, the Profiler associates the provided Unity Object (for example, a Texture or a Mesh) with the profiling sample. This is similar to the way that ProfilerMarker.Begin(Object) handles the contextObject parameter.
