Abstract
A method and apparatus for automatic alignment of manipulated objects in two-dimensional and three-dimensional graphic space. The present invention provides an alignment field gradient which emanates from objects surrounding the manipulated object(s). As a user manipulates an object, the present invention attracts the manipulated object into an aligned position and orientation with another object(s) in the displayed three-dimensional display space. The present invention provides alignment of all combinations of vertices, edges and planar faces for three-dimensional polyhedral objects and for all combinations of vertices and edges for two-dimensional polygonal objects.
