Parameters

srcThe resource to read the data from.
sizeSize in bytes of the data to be retrieved from the ComputeBuffer.
offsetOffset in bytes in the ComputeBuffer.
mipIndexThe index of the mipmap to be fetched.
dstFormatThe target TextureFormat of the data. Conversion will happen automatically if format is different from the format stored on GPU.
xStarting X coordinate in pixels of the Texture data to be fetched.
widthWidth in pixels of the Texture data to be fetched.
yStarting Y coordinate in pixels of the Texture data to be fetched.
heightHeight in pixels of the Texture data to be fetched.
zStart Z coordinate in pixels for the Texture3D being fetched. Index of Start layer for TextureCube, Texture2DArray and TextureCubeArray being fetched.
depthDepth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray.

Returns

AsyncGPUReadbackRequest An AsyncGPUReadbackRequest that can be used to both access the data and check whether it is available.

Description

Triggers a request to asynchronously fetch the data from a GPU resource.

If an error occurs due to some invalid arguments being passed to this method, a request with an error is returned. If a request with an error is returned, calling AsyncGPUReadbackRequest.hasError on that request will return true.
