Parameters

src The resource to read the data from.
size Size in bytes of the data to be retrieved from the ComputeBuffer or GraphicsBuffer.
offset Offset in bytes in the ComputeBuffer or GraphicsBuffer.
mipIndex The index of the mipmap to be fetched.
dstFormat The target TextureFormat of the data. Conversion will happen automatically if format is different from the format stored on GPU.
x Starting X coordinate in pixels of the Texture data to be fetched.
y Starting Y coordinate in pixels of the Texture data to be fetched.
z Start Z coordinate in pixels for the Texture3D being fetched. Index of Start layer for TextureCube, Texture2DArray and TextureCubeArray being fetched.
depth Depth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray.
width Width in pixels of the Texture data to be fetched.
height Height in pixels of the Texture data to be fetched.
callback A delegate System.Action called once the request is fullfilled. The done request is passed as parameter to the System.Action.

Description

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