Artists and illustrators enhance perception of features with lighting that is locally consistent and globally inconsistent. Inspired by these techniques, we design the placement of light sources to convey a greater sense of realism and better perception of shape with globally inconsistent lighting. Our algorithm segments the objects into local surface patches and uses a number of perceptual heuristics, such as highlights, shadows, and silhouettes, to enhance the perception of shape. We show our results on scientific and sculptured datasets.}, keywords = {inconsistent lighting, light placement, lighting design, proximity shadows, scientific illustration, silhouette enhancement}, isbn = {0-7803-8788-0}, doi = {10.1109/VISUAL.2004.62}, url = {http://dx.doi.org/10.1109/VISUAL.2004.62}, author = {Lee,Chang Ha and Hao,Xuejun and Varshney, Amitabh} }
