Parameters

output Reference to a NativeArray to write the data into.
src The resource to read the data from.
size The size in bytes of the data to be retrieved from the ComputeBuffer or GraphicsBuffer.
offset The offset in bytes in the ComputeBuffer or GraphicsBuffer.
mipIndex The index of the mipmap to be retrieved.
dstFormat The target TextureFormat of the data. If the target format is different from the format stored on the GPU, the conversion is automatic.
x The starting X coordinate in pixels of the Texture data to be retrieved.
y The starting Y coordinate in pixels of the Texture data to be retrieved.
z The starting Z coordinate in pixels for the Texture3D being retrieved. Index of Start layer for TextureCube, Texture2DArray and TextureCubeArray being retrieved.
depth The depth in pixels for Texture3D being retrieved. Number of layers for TextureCube, TextureArray and TextureCubeArray.
width The width in pixels of the Texture data to be retrieved.
height The height in pixels of the Texture data to be retrieved.
callback A delegate System.Action called when the request is completed. The done request is passed as a parameter to the System.Action callback.

Description

Adds an asynchonous GPU readback request command to the command buffer.
