                         animated cartoons. Computer assisted methods have been 
                         incorporated in animation/illustration systems to reduce the 
                         artists' effort. This paper presents a new strategy for 
                         illumination and colorization of 2D drawings based on a 
                         region-tree. Starting from a hand-drawn cartoon, it extracts 
                         geometric and topological information and builds a tree structure, 
                         ensuring independence among parts of the drawing, such as curves 
                         and regions. Based on this structure and its attributes, a 
                         colorization method that propagates through consecutive frames of 
                         animation is proposed, together with an interpolation method that 
                         accurately computes a normal mapping for the illumination process. 
                         Different operators on curve and region attributes can be applied 
                         independently, obtaining different rendering effects.",
