vPlanarProjection

Simpy set up to 4 points in 3D and generate CornerPin (matchmove/stabilize) and/or its matrix, which can be then used in RotoPaint/SplineWarp/GridWarp nodes

This gizmo was initially developed as a tool for fixing drift in complex matchmove shots in post, rather than spending time to solve unsolvable shots, but during the time it served as a perfect tool for rotoscoping or cornerpining (instead of using 3d cards).

Workflow:

1) connect the camera

2) select the points in 3d viewport (you can use vertex selection mode, or move handles manually)

3) generate 2D projection points

4) generate matrix

5) use inbuild functions to generate Rotopaint/SplineWarp or GridWarp node, which is tracked with generated points
