How to use GPUImageTransformFilter to realize perspective transformation?

Hello, how do I implement https://bl.ocks.org/mbostock/. with a shader, which is also controlled by 4 contacts.

this problem is aimed at the Objective-C language environment on the iOS platform.
I want to assign it directly through the CATransform3D, of the layer to the GPUImageTransformFilter
filter in the GPUImage of the third-party library, so that the texture is deformed as well as the layer.
what should I do? What kind of thinking should it be?
also ask the god to give us some advice.
