This paper presents our preliminary results on regular meshes in which all faces have the same size and all vertices have the same valence. A regular mesh is denoted by (n, m, g) where n is the number of the sides of ...

Within the large spectrum of possible VR application areas, automotive applications were among the first to appear, and are among the most demanding. Technology has not been sufficiently sophisticated for many tasks. The troubling thought is that we are happy to push the technology envelope, but don't really know how useful this technology is, or can be. Could I do my job even if I had a real-time, ortho-stereoscopic, head-tracked, multi-viewer, wide-field-of-view, high-dynamic-range display with eye-limiting acuity?

In this paper, we present a set of generalized "local" mesh operators. Local operators are those that operate on a single face without affecting the rest of the mesh. Boundary edges of the chosen face also stay the same. We have identified two types of local operators: (1) Extrusions that create generalized pipes in which bottom and top polygons have the same number of sides, and (2) Stellations that create generalized pyramids, where there is a top vertex instead of top polygon. Our operators can create extrusions that are regular polyhedra including dodecahedron, icosa-hedron, octahedron and tetrahedron. The tetrahedron is created using the stellation operator, which is also useful to create generalized versions of Kepler and Poinsot solids.

Ambience and immersive technological environments allow us to explore some basics of human pragmatics that lie beyond linguistics, intentionality and the subject-agency perspectives of human interaction. We focus on gesture and the body in sense-making and propose a discussion drawing on a non-dualist and agent-free account of embodied, material experience. By agent-free we mean an approach that does not presume a monolithic subject. Moreover, we deal with the problem of intersubjectivity by studying the human coordination of activity without appealing to a transmission theory of communication. [6] We achieve this by considering how gesture spans multiple bodies and how aesthetic design works with this and facilitates it. The paper is in two parts, the first part covers movement studies, focusing on gesture and body movement, drawing on the acting and pragmatics, and the second part develops this with the example of the TGarden, a responsive play space for experimental performance augmented by gesturally nuanced computational media.

This article reviews the ongoing evolution of context awareness technologies in mobile devices using personal media as an illustrative application domain. Augmented with metadata, files containing personal media can include significant information about the contexts they describe. The article discusses personal media applications from two different perspectives: (1) through an example that describes the use of context data in a personal media diary application, and (2) with a classification of context architectures that includes three classes of context-aware mobile systems (inbound, shared, and network assisted). These systems are classified on the basis of such factors as their architecture, data flow types, privacy, and interoperability requirements. The article concludes by discussing implications for research and practice.
In this paper, we present a subdivision-inspired scheme to construct generalized Sierpinski polyhedron. Unlike usual Sierpinski polyhedra construction schemes, which create either an infinite set of disconnected tetra...

Triangular and quadrilateral meshes are commonly used in computer graphics applications. We analyze the topological existence of meshes that consist of n-sided faces where n is greater than 4 such as pentagonal and hexagonal meshes. We show that it is possible to represent any 2-manifold with a mesh that is made up of only pentagons. We also show that the meshes that consist of only polygons with more than five sides cannot represent all 2-manifolds. We present a pentagonalization (or pentagonal conversion) scheme that can create a pentagonal mesh from any arbitrary mesh structure. We also introduce a pentagonal preservation scheme that can create a pentagonal mesh from any pentagonal mesh.
