Abstract

An apparatus for processing an effect using style lines, includes a contour line creation unit for creating contour lines using polygons of a three-dimensional (3D) object and location information of a camera; a style line creation unit for putting edge lists, extracted at the time of creating the contour lines, into groups, and creating one or more style lines for each of the groups; and an effect processing unit for representing a line style by inserting the created style lines inside and outside a contour line corresponding to the group. Therefore, representation to appear to have been drawn by a human hand is enabled by adding style lines to existing contour lines in order to represent a line style that belongs to various styles of non-photo realistic rendering.
