public void RequestAsyncReadbackIntoNativeSlice(ref NativeSlice<T> output, Texture src, int mipIndex, int x, int width, int y, int height, int z, int depth, Experimental.Rendering.GraphicsFormat dstFormat, Action<AsyncGPUReadbackRequest> callback);

Parameters

output Reference to a NativeSlice to write the data into.
src The resource to read the data from.
mipIndex The index of the mipmap to fetch.
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 fetch.
y The starting y-coordinate, in pixels, of the Texture data to fetch.
z The starting z-coordinate, in pixels, of the Texture3D to fetch. For TextureCube, Texture2DArray, and TextureCubeArray, this is the index of the start layer.
width The width, in pixels, of the Texture data to fetch.
height The height, in pixels, of the Texture data to fetch.
depth The depth, in pixels of the Texture3D to fetch. For TextureCube, Texture2DArray, and TextureCubeArray, this is the number of layers to retrieve.
callback A delegate System.Action to call after Unity completes the request. When Unity calls the delegate, it passes the completed request as a parameter to the System.Action.

Description

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


public void RequestAsyncReadbackIntoNativeSlice(ref NativeSlice<T> output, ComputeBuffer src, Action<AsyncGPUReadbackRequest> callback);
public void RequestAsyncReadbackIntoNativeSlice(ref NativeSlice<T> output, ComputeBuffer src, int size, int offset, Action<AsyncGPUReadbackRequest> callback);
public void RequestAsyncReadbackIntoNativeSlice(ref NativeSlice<T> output, GraphicsBuffer src, Action<AsyncGPUReadbackRequest> callback);
public void RequestAsyncReadbackIntoNativeSlice(ref NativeSlice<T> output, GraphicsBuffer src, int size, int offset, Action<AsyncGPUReadbackRequest> callback);

Parameters

output Reference to a NativeSlice to write the data into.
src The resource to read the data from.
size The size, in bytes, of the data to retrieve from the ComputeBuffer or GraphicsBuffer.
offset The offset in bytes in the ComputeBuffer or GraphicsBuffer.
callback A delegate System.Action to call after Unity completes the request. When Unity calls the delegate, it passes the completed request as a parameter to the System.Action.

Description

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