Abstract
Disclosed is a method of rendering a plurality of graphical objects. The method generates a region graph using at least a plurality of intersection points of the graphical objects. The intersection points identify disjoint regions each representing a particular combination of the graphical objects, in which the region graph has at least one region graph link, and defines a relationship between the regions. A contributing level and an activating direction are assigned to at least one of the region graph links, the level and the activation direction defining an appearance of the region associated with said region graph link. The method then renders the plurality of graphical objects using the assigned contributing level and activating direction of the region graph links by traversing the region graph to determine at least one contributing level for each region in the region graph using the assigned contributing level and the activating direction.
