Abstract
The method of selectively rendering graphic objects three-dimensional of the present invention is realized by acquiring a relative position between each pixel of the 2-D graphic object and the outer closed curve vout through the definition of an internal closed curve vin and an outer closed curve vout. Then, by selecting with a mask the area to display 3-D effects, a directional relation is obtained. Next, z-axis parameters corresponding to each pixel are generated with an effect function and a corresponding selective 3-D graphic object is rendered based upon the 2-D graphic object and the z-axis parameters by means of ERM functions.
