1. A method for generating a process trajectory, comprising: displaying a normalized image of an object on a display device of a computer system, the object including a surface that is to be processed using an end effector; providing a number of predefined trajectories in a memory of the computer system, each of the predefined trajectories defining a motion of the end effector to process a surface of one of a number of spatial definitions; generating the process trajectory for the end effector to process the surface of the object by associating at least one of the predefined trajectories with the normalized image.
