参数

output Reference to a NativeSlice to write the data into.
src 要从中读取数据的资源。
mipIndex The index of the mipmap to fetch.
dstFormat 数据的目标 TextureFormat。如果目标格式与 GPU 中存储的格式不同，则转换是自动进行的。
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

向命令缓冲区添加异步 GPU 回读请求命令。

参数

output Reference to a NativeSlice to write the data into.
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.
