Rendering Illustrations using a Two-Dimensional Rendering Engine

摘要

A rendering engine is described that implements rendering techniques to render 2D illustrations by assigning light values to objects that define an illustration ‘inside out’. Light values may be assigned to a first object and subsequently inherited by objects that are hierarchly related to the first object. The light values assigned to the objects may include a light variable that depends on a relationship between the two or more groups of objects. Various rendering techniques may be employed by the rendering engine to render illustrations that are both customizable and realistic in appearance.

1. A method implemented by a computing device, the method comprising:
rendering a two-dimensional (2D) image that includes first and second sets of image objects in which a distance of the second set of image object to a light source is less than a distance of the first set of image objects to the light source, the rendering including:
assigning one or more values to the first set of image objects to indicate a level of light for each image object in the first set of objects;calculating one or more values to indicate a level of light for the second set of image objects based, at least in part, on the one or more values assigned to the first set of image objects; andrendering the 2D image to include the first and second sets of image objects.
