Abstract: The normal vector at a node on the discrete surface is not unique, when a surface discretized by triangular elements. A widely used technique to estimate the normal vector at a giving node is a weighted average of the exact normal of the surrounding triangular elements. In this paper, two weight factors proposed to estimate the normal vector at a node in the triangular mesh. The numerical comparisons are performed between the new weights and with some existing weights for the two knowing geometrical surface.
Keywords: Averaging Normal Vector, Triangular Mesh, Weight Factors, Toroidal Surface
