Interactive Projection Mapping

Dynamic Urban Projection Mapping †

“Dynamic projection mapping” is a variation of the best-known “projection mapping”. It considers the perceptual analysis of the urban landscape in which the video projection and the observer’s displacement speed are hypothesized. This latter, in particular, is variable and may depend on factors not directly controllable by the driver (slowdowns due to accidents, rallies, etc.). This speed can b...

Interactive Maximum Projection Volume Rendering

Maximum projection is a volume rendering technique that, for each pixel, finds the maximum intensity along a projector. For certain important classes of data, this is an approximation to summation rendering which produces superior visualizations. In this paper we will show how maximum projection rendering with additional depth cues can be implemented using simple affine transformations in objec...

Interactive Tone Mapping

Tone mapping and visual adaptation are crucial for the generation of static, photorealistic images. A largely unexplored problem is the simulation of adaptation and its changes over time on the visual appearance of a scene. These changes are important in interactive applications, including walkthroughs or games, where effects such as dazzling, slow dark-adaptation, or more subtle effects of vis...

Interactive Horizon Mapping

Shadows play an important role in perceiving the shape and texture of an object. While some previous interactive shadowing methods are appropriate for casting shadows on other geometry they can not be applied to bump maps (which contain no explicit geometry.) Horizon Mapping is a technique used to compute shadows for bump-mapped surfaces. We map the technique into modern graphicsAPI’s and exten...
