Corner Pin Node
The Corner Pin node uses explicit corner values for a plane warp transformation. It works like the Plane Track Deform node, but without using “plane track” data from the Movie Clip Editor.
Standard image input.
Four vector inputs to define the plane warping. (Z component of vector inputs is ignored.)
This node has no properties.
Standard image output. (The image after distorting.)
A black-and-white alpha mask of the plane.
In the example above, the image of the bird is distorted by the vectors specified by the Corner Pin node.
