Abstract:
A method of rendering a two-dimensional nonphotorealistic image from data for a three-dimensional model, comprising:rendering a shaded image based on the data, the shaded image comprising a two-dimensional nonphotorealistic image having no outlines; and rendering an outline image based on the data, the outline image comprising a two-dimensional image and augmenting the shaded image to obtain the two-dimensional nonphotorealistic image, the outline image augmenting the shaded image by moving in front of the shaded image in a three-dimensional buffer relative to a virtual eyepoint; wherein two parameters define how the outline image moves in front of the shaded image, the two parameters comprising a first parameter and a second parameter, the first parameter weighting a slope of a polygon associated with the outline image to move a portion of the outline image that corresponds to the polygon relative to the virtual eyepoint, and the second parameter weighting all portions of the outline image equally to move an entirety of the outline image relative to the virtual eyepoint.
