1. A method, performed by a computer, of manipulating graphic objects in a 3D scene, the method comprising:

  • receiving input from a user and using the input to identify a plurality of features of a graphic object, one of the plurality of features of the graphic object comprising an edge;

    defining a coordinate space with each item of input received from the user and based on the plurality of identified features of the graphic object in the 3D scene by determining at least one of a motion surface and a motion plane; and

    constraining a range of motion based on the defined coordinate system, wherein the determining comprises finding a plane that is perpendicular to an average of normals of polygons touching the edge of the graphic object.
