“…Thus in addition to geometric alignment between projected images, it is also necessary to achieve intensity normalization. The problem of generating seamless images using multiple projectors has been explored for large wide-field-of-view displays [Panoram] [Trimensions] [Raskar99], as well as two-dimensional arrays of flat projections [Humphreys99] [Czernuszenko97]. In such cases, the overlap region is typically a (well-defined) contiguous region on display surface as well as in each projectors frame buffer.…”

Shader Lamps: Animating Real Objects With Image-Based Illumination

We describe a new paradigm for three-dimensional computer graphics, using projectors to graphically animate physical objects in the real world. The idea is to replace a physical object-with its inherent color, texture, and material properties-with a neutral object and projected imagery, reproducing the original appearance directly on the object. Furthermore the projected imagery can be used to reproduce alternative appearances, including alternate shading, lighting, and even animation. Because the approach is to effectively "lift" the visual properties of the object into the projector, we call the projectors shader lamps .Some limited effects have previously been demonstrated along these lines for specific applications, however the real challenges to realizing this as a new medium for computer graphics lies in addressing the problems related to complete illumination of nontrivial physical objects. Our approach offers a very compelling method of visualization for a variety of applications including dynamic mechanical and architectural models, animated or "living" dioramas, artistic effects, entertainment, and even general visualization for problems that have meaningful physical shape representations. We present and demonstrate methods for using multiple shader lamps to animate physical objects of varying complexity, from a flower vase, to some wooden blocks, to a model of the Taj Mahal.

Abstract. Multi-user communication and interaction via public displays together the pervasive and seamless access to the WWW in public areas via mobile phones or handheld devices is enabled via the WebWall system. A software framework for the operation of WebWalls has been developed, strictly separating WebWall access technologies (like HTTP, email, SMS, WAP, EMS, MMS or even simple paging protocols found on mobile phones) from the physical display technologies used and the presentation logic involved. The architecture integrates ubiquitous wireless networks (GSM, IEEE802.11b), allowing a vast community of mobile users to access the WWW via public communication displays in an ad-hoc mode. A centralized backend infrastructure hosting content posted by users in a display independent format has been developed together with rendering engines exploiting the particular features of the respective physical output devices installed in public areas like airports, trainstations, public buildings, lecture halls, fun and leisure centres and even car navigation systems. A variety of different modular service classes has been developed to support the posting or pulling of WWW media elements ranging from simple sticky notes, opinion polls, auctions, image and video galleries to mobile phone controlled web browsing.

“…Visual immersion needs specific, expensive and cumbersome hardware, such as head-worn displays (HMDs), large displays or CAVE systems (Sutcliffe et al, 2006). HMDs offer a good level of immersion, but often suffer of a small field of view and isolate the user and his/her body both from the real and the virtual world (Czernuszenko et al, 1997). Spatially Immersive Displays (SIDs), like wall-displays and CAVEs, have the advantage of being multi-user, to allow persons to be physically within the virtual environment and feature a wide field of view.…”

Abstract:CAVE systems are nowadays one of the best Virtual Reality (VR) immersive devices available for rendering virtual environments. Unfortunately, such kind of hardware is extremely expensive, complex and cumbersome, thus limited in its spread. Several cheaper solutions already exist, but they implement usually only a subset of features of a professional CAVE. In this paper we describe how we have built a low cost CAVE with four screens (three walls and a floor), stereographic rendering and user tracking by only using hardware commonly available on the market and free software, we show the different solutions and work-around we implemented to solve the problems we encountered and we conclude with an evaluation of our system by using two applications we developed with it.
