Abstract

Image snapping is the technique to move a cursor position to a nearby feature such as edges in a 2D image when the cursor is located by a user. This paper proposes a new snapping technique called the geometric snapping that naturally moves the cursor position to a geometric feature in 3D meshes. The cursor movement is based on the approximate curvatures defined for measuring the geometric characteristics of the 3D meshes. The proposed geometric snapping can be applied to extracting geometric features of 3D mesh models in many CAD and graphics systems.
