Stylized Glass Paintings for Non-Photorealistic Rendered scenes

摘要

Non-photorealistic Rendering (NPR) has inspired many researchers to investigate a variety of techniques to simulate the style of artists. Recent work has resulted in methods of crayon stroke generation and cartoon style rendering. In this paper, we propose a stylized form of a glass painting to be used in cartoon rendered scenes and animations. Sand blasted glass is used as the base (canvas) and the medium of coloring is crayons. The paper describes an algorithm to model a sand blasted glass based on "fog-based height maps". We have also introduced a new and faster method to model a crayon texture using height maps and pigment adhesion techniques. Finally the crayon-textured image is mapped on the sand blasted glass generating a new and stylized form of glass painting. The image painted on glass is also highlighted with black outlines that are again crayon texture based.
