A New Framework For Non-Photorealistic Rendering
Ronald N. Perry · 2006
Non-photorealistic rendering, or NPR, has emerged as an important field of computer graphics. In this paper, we first identify the common elements in numerous and diverse NPR styles. We then propose a new framework for NPR based on adaptively sampled distance fields (ADFs). By representing a model as an ADF, we unify several operations common in artistic rendering. Furthermore, because ADFs can represent both hard surfaces and soft organic volumetric forms, opportunities exist to develop new volumetric NPR techniques in this single framework. We propose such a volumetric style. 1.
