CornerPin Matrix

Tutorial and explanation at the link: http://www.andreageremia.it/tutorial_matrix_transform.html

 I've modified the Transform node of Nuke, adding a Matrix to visualize the same transformation with a Matrix4x4.

In this example, connect the CornerPin_Matrix to the image and modify the pins.

Modify the pins and see how the matrix changes.

There is a checkbox useful to invert the Matrix. In this case we can copy the matrix in another CornerPin and the copy the inverse matrix in another CornerPin. The final result will be the original picture

In  this case you can modify the picture with the Matrix and add other changes with the Pins.
