参数

output 要将数据写入其中的 NativeArray 的引用。
src 要从中读取数据的资源。
mipIndex The index of the mipmap to fetch.
dstFormat The target TextureFormat of the data. Conversion happens automatically if this format is different from the format stored on the GPU.
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.

描述

public void RequestAsyncReadbackIntoNativeArray (ref NativeArray<T> output, GraphicsBuffer src, int size, int offset, Action<AsyncGPUReadbackRequest> callback);

参数

output 要将数据写入其中的 NativeArray 的引用。
src 要从中读取数据的资源。
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.
