説明

Represents an asynchronous request for a GPU resource.

Use AsyncGPUReadback.Request to retrieve an asynchronous request for a GPU resource. Pending requests are automatically updated each frame. The result is accessible only for a single frame once is successfully fulfilled and this request is then disposed of in the following frame. Common uses for this are to query AsyncGPUReadbackRequest.done each frame (or within a coroutine) and then call AsyncGPUReadbackRequest.GetData if the AsyncGPUReadbackRequest.hasError is false. You don't have to manage the request lifetime as this is managed internally. A request that has been disposed of will result in the AsyncGPUReadbackRequest.hasError property being true. See Also:AsyncGPUReadback.
