Non-photorealistic computer graphics is a multidisciplinary field in the research community, involving computer arts,computer graphics,computer vision,digital image/video processing and visual cognitive psychology.It aims at the computer generation of images and animations that are made in part“by hand”in appearance,and are characterized by their use of randomness,abstraction,ambiguity, or arbitrariness rather than completeness and adherence to the portrayed objects’properties.In essence,it mimics the eyes and minds of artists and designers to create,view and depict the graphics world,effectively carrying-out the visual communication between computers and human beings.
Coverage and Audience
This book mainly focuses on the following five core issues in non-photorealistic computer graphics.
(1)How to create the paintings,artworks or sculptures from a digitized blank canvas or a standard shape with the tools simulated by the computer.
(2)How to convert a series of reference images into the resultant depiction with the desired visual effect.
(3)How to automatically generate the artistic rendition or technical illustrations from the 3D models in terms of the stylized parameters.
(4)How to produce the comprehensive and expressive visualizations from a set of graphical and textual information on the basis of the semantic meanings to be conveyed.
(5)How to speed up the production of cartoon animation by computer- assisted refinement of traditional pipeline and the exploration of novel approaches.
