我有一个Renderscript其处理是给予在输出到分配的图像。 我想用这个分配作为纹理在我的OpenGL程序，但我不知道怎么去从分配纹理ID。

I have a Renderscript which processes an image that is given in output to an Allocation. I want to use this Allocation as a texture in my OpenGL program but I don't know how to get a texture ID from the Allocation.

在另一方面，我知道我可以使用一个图形Renderscript，但既然已经去precated，我想一定要达到相同的结果一些其他的方式。

On the other hand, I know I could use a graphic Renderscript, but since it has been deprecated, I guess there must be some other way to achieve the same result.

推荐答案

指定USAGE_IO_OUTPUT当您创建的分配。假设您正在生成的纹理数据的脚本，你还要补充USAGE_SCRIPT。然后，您可以调用

Specify USAGE_IO_OUTPUT when you create the Allocation. Assuming you are generating the texture data in a script you would also add USAGE_SCRIPT. You can then call

Allocation.setSurface（theGLSurface）

Allocation.setSurface(theGLSurface)

要分配链接到一个纹理。每当你想更新你需要调用脚本的内容质感。

to link the allocation to a texture. Each time you want to update the texture with the contents of the script you need to call.

Allocation.ioSend（）

Allocation.ioSend()

这将移动数据，而无需做额外的拷贝。

This will move the data without making extra copies.
