A processing method for rendering a planar arrow object into a 3-dimensional arrow object. The processing method of this invention comprises the steps as follows: setting a total length of an arrow object, wherein the arrow object includes at least one end having the arrowhead portion; determining the arrowhead portion and the line portion of the arrow object; creating a corresponding first mapping data of the line portion, wherein the first mapping data represents the third axis data associated with the pixels of the line portion; extracting a corresponding arrowhead graphical data of the arrowhead portion; creating a corresponding second mapping data of the graphical data of the arrowhead portion, wherein the second mapping data represents the third axis data corresponding to the pixels of the graphical data of the arrowhead portion; creating the respectively corresponding masks of the line portion and the arrowhead portion; superimposing the arrowhead mask and the line mask so as to create an arrow object mask; and creating a 3-dimensional image of the arrow object according to the first mapping data and the second mapping data and utilizing the arrow object mask.
