ABSTRACT
We introduce a system for urban planning - called Urp -that integrates functions addressing a broad range of the fields concerns into a single, physically based workbench setting. The I/O Bulb infrastructure on which the application is based allows physical architectural models placed on an ordinary table surface to cast shadows accurate for arbitrary times of day; to throw reflections off glass facade surfaces; to affect a real-time and visually coincident simulation of pedestrian-level windflow; and so on.
We then use comparisons among Urp and several earlier I/O Bulb applications as the basis for an understanding of luminous-tangible interactions, which result whenever an interface distributes meaning and functionality between physical objects and visual information projectively coupled to those objects. Finally, we briefly discuss two issues common to all such systems, offering them as informal thought-tools for the design and analysis of luminous-tangible interfaces.

Splatting indirect illumination
I3D '06: Proceedings of the 2006 symposium on Interactive 3D graphics and gamesIn this paper we present a novel method for plausible real-time rendering of indirect illumination effects for diffuse and non-diffuse surfaces. The scene geometry causing indirect illumination is captured by an extended shadow map, as proposed in ...
Interactive Approximate Rendering of Reflections, Refractions, and Caustics
Reflections, refractions, and caustics are very important for rendering global illumination images. Although many methods can be applied to generate these effects, the rendering performance is not satisfactory for interactive applications. In this paper,...
