In order to extend the set of classic presentation variables, we present the use of hybrid rendering styles combining photorealistic (PR) and non-photorealistic (NPR) techniques. Hybrid images cannot simply be generated by combining classic PR rendering with the addition of NPR line styles. Instead, different combinations of photorealism and non-photorealism are applied to different parts of the scene simultaneously. Dynamic presentations are created by a smooth blending between the different styles used. Two blending approaches are presented: use of the -channel and modification of objects’ emissive color. Any parameterization of these blending techniques are supported by an analysis of perceptional constraints leading to the definition of a dynamics stimulus window. Possible application scenarios are presented for a technical as well as a medical model.
