A system comprising:
- a video processor configured to convert a matte shape to 3D spatial coordinates and redrawn with lens and camera data matching the live action camera and lens and to use the matte shape to selectively process portions of a live action image in combination with at least one other image to generate a composited image.
A method comprising:
- selecting points on a computer screen to generate a rough outline around an object to be removed or preserved from a live action image from a live action camera;
- the selecting including beginning or ending the outline at an edge of the screen;
- the beginning or ending causing the matte to be automatically extended a predetermined distance out from the edge of the screen without requiring the camera to move back and forth;
- and
- the matte being comprised of three-dimensional geometry in an arbitrary three-dimensional plane, so that areas extended past the geometry visible to the user are projected into three-dimensional space.

A method comprising:
- generating a 2D outline around an object to be removed or preserved in a 2D display of a live action image from a live action camera;
- converting the 2D outline to a 3D mesh on a plane normal to the optical axis of the original live action camera location;
- and
- projecting the 3D mesh from a virtual camera having the same position and orientation as the live action camera to line up the 3D mesh with elements of the live action image.
1 more element
A method comprising:
- manipulating a 3D object via a 2D interface by forcing 3D points to lie in a plane and calculating their 3D positions by dragging around a 2D dot on a 2D interface;
- wherein the plane is perpendicular to the tracked camera position from where the points were original drawn.
