【Abstract】 A novel formula for the estimation of triangular mesh vertex normal vector is presented.Instead of area weighted,this formula is area and angle weighted.Based on the formula,a new method for the estimation of triangular mesh discrete curvature is put forward.This method is the improvement of Taubin’s triangular mesh discrete curvature estimation method,by replacing triangle area weights with triangle centroid weights.Example shows that the estimation results of the presented formula and method is more accurate than that of existing methods.更多还原
