Towards mapping the field of non-photorealistic rendering

Amy A. Gooch
2010 Proceedings of the 8th International Symposium on Non-Photorealistic Animation and Rendering - NPAR 10  
Abstract Non-photorealistic rendering (NPR) as a field of research is generally described by what it is not and as a result it is often hard to embrace the strengths of non-photorealistic rendering as  ...  The aim of this paper is to provide a type of road map to stimulate the future growth of the area of non-photorealistic rendering.  ...  The creation of change-based mappings for images may have a broad impact on the field of non-photorealistic rendering, especially with respect to image representation and manipulation.  ...

Interactive Multi-volume Visualization [chapter]

Brett Wilson, Eric B. Lum, Kwan-Liu Ma
2002 Lecture Notes in Computer Science  
This paper is concerned with simultaneous visualization of two or more volumes, which may be from different imaging modalities or numerical simulations for the same subject of study.  ...  The main visualization challenge is to establish visual correspondences while maintaining distinctions among multiple volumes. One solution is to use different rendering styles for different volumes.  ...  We implement this non-photorealistic rendering style by modulating each textured polygon drawn in the rendering processes with a color that is selected based on the distance from the viewpoint.  ...
