CV Project To Plane

Drops one axis of 3D points to get a 2D ORTHOGRAPHIC view - a top-down (XZ), front (XY) or side (YZ) projection of a 3D point cloud or camera trajectory, ready for 'CV Draw Points' / 'CV Draw Polygon'. (For a perspective render use cv2.projectPoints with a camera matrix instead.) None/empty input passes through as an empty array.
