Abstract:
Not only photo-realistic rendering but non-photo-realistic rendering is considered an important research topic in artistic image synthesis. However, little attention has been given to colored pencil drawing. This paper proposes a volume graphics model for colored pencil drawing. The model consists of three sub-models, which describe in a volumetric fashion, the microstructure of paper, pigment distribution on paper, and pigment redistribution, respectively. The model takes advantage of volumetric offset distance accessibility and line integral convolution, and thus is highly controllable with a small number of parameters. A couple of synthesized color pencil drawing data sets are rendered using an existing volume visualizer to empirically prove that the model is descriptive enough to produce realistic images of colored pencil drawing.
