The invention relates to non-photorealistic rendering in
computer graphics, in particular to digital
simulation and synthesis with artistic style of Yunnan heavy-color painting, and belongs to the technical field of non-photorealistic graphic rendering. The digital
simulation and synthesis are characterized in that: the digital
simulation and synthesis comprise an establishment and management module of a Yunnan heavy-color painting basic graphic element
library, a graphic element
library-based Yunnan heavy-color painting traditional delineation drawing rendering module, and a Yunnan heavy-color painting traditional delineation drawing-based coloring and rendering module. The basic graphic element
library is used for providing graphic elements needed by foreground traditional delineation drawings, such as hair, facial forms, trunks and the like. The Yunnan heavy-color painting traditional delineation drawing rendering module can select appropriate graphic elements from the graphic element library to combine the graphic elements by
layers so as to generate the Yunnan heavy-color painting traditional delineation drawings. In order to harmoniously collocate all the graphic elements, a
system provides multiple kinds of operation for the graphic elements, such as translation, selection, scaling and the like and can modify the shapes of the graphic elements at the same time. The Yunnan heavy-color painting traditional delineation drawing-based coloring and rendering module is in charge of coloring the traditional delineation drawings, and the effects of coloring can reflect texture characteristics and color characteristics in an original drawing of the heavy-color painting, and special characteristic simulation of the Yunnan heavy-color painting, such as character edge hollow sense, background fusion and the like is realized.
