3D computer graphics modeling software that is meant to be operated in a 2D environment comes equipped with a mouse and a 2D display; it is difficult to use these tools to edit 3D mesh objects. This paper proposes an interface for a 3D computer graphics object editing tool to facilitate editing of 3D mesh computer graphics. The interface is able to represent a sense of depth via a perspective view and the gradation of tone color on a 2D display
