Abstract
A video editing method that includes displaying a two-dimensional projection of a representation of a projection surface. This projection is derived from a three-dimensional position of the surface. A handle is displayed attached to the projection, and the position of the surface is updated in a manner corresponding to the displacement of a cursor at the handle. The method further includes displaying a second projection derived from the updated position, and redisplaying the handle attached to it.
