Illustrative rendering often also depicted as non-photorealistic rendering or stylized rendering, employs abstraction techniques to convey the relevant information, and de-emphasize less important details. The question remains how this abstraction process is guided and in particular how can we ensure that relevant information is maintained. Consequently, research on illustrative rendering needs to address how the information is perceived by the human observer, next to the investigation of algorithmic aspects.
conveying interested information and de-emphasize less importnat details, also be called Focus + Context. There are many visualization work in this topic. It includes three apspects: Geometirc Transformation, Optical Transformation, Viewing Transformation.
the Geometric Transfomration mainly refers to deformation. Recent year Carlos. D. Correa has many papers in this topic, and do some good work, such as discontinuous displacement mapping for volume graphics. illustrative deformation for data exploration. And the Stefan Bruckner: exploded view of volume data.
Optical Transformation refers to just work in the transfer function shading, coutour to implement F+C. Vienna Univeristy of Technolgy has many good work, such as style transfer function for illustrative volume renderng. enahancing detph- percetption with flexible volumetric halos.
The view transformation includes changes the viewing system and camera parameters, leading to some viusal distortion. For example, fishesyes views, and magnification lenses.
All of these work have many good papers, which topic I should work? In transfer function, there are many good work. At the same time, many researchers transform the baisc transfer function problem to such as new histogram interface, motion-based rendering. If I foucs work on in intuitive transfer function, I think I cann't get some good papers.
