The generation of good-looking large textures for arbitrary surfaces as well as the distribution of many objects within an interactive ecosystem are very important. The restrictions of graphics memory size limit the desired dimensions of information content. In order to create more and more realistic looking environments, computer graphics has to make use of all algorithmic capabilities. Wang t...

Utilizing principles from parallel and distributed processing combined with inspiration from modular robotics, we developed the modular interactive tiles. As an educational tool, the modular interactive tiles facilitate the learning of multi-agent systems and interactive agent-based games. The modular and physical property of the tiles provides students with hands-on experience in exploring the...

Rudolph showed that the orbits of any measurable, measure preserving R action can be measurably tiled by 2 rectangles and asked if this number of tiles is optimal for d > 1. In this paper, using a tiling of R by notched cubes, we show that d + 1 tiles suffice. Furthermore, using a detailed analysis of the set of invariant measures on tilings of R by two rectangles, we show that while for R acti...

In this paper we propose to pave indoor floors with “communicating” tiles in order to extend perception and communication of mobile agents and more generally to implement environment-based multi-agent models. Each tile supports a real-time process which ensures communication with its neighbours and any agent laid on it. We details algorithms required for tiles to interact with mobile agents and...

This paper describes a robust method for recovering an optimal DEM and its variance from multiple, randomly orientated views of a surface. The method generates a set of DEM tiles in a common coordinate system from multiple overlapping images, and then employs the concept of self-consistency to detect and remove errors from the tiles. The clean tiles are averaged together to form a low noise com...

Our approach is to chop matrixes into an array of square tiles of uniform size and use DryadLINQ to construct and execute a distributed execution plan for passing tiles between compute nodes from stage to stage of the computation of a large matrix operation. We use HPC Dryad Beta [5] running on an 85-node cluster for distributed execution and BLAS routines from the Intel R © Math Kernel Libary ...

In computer graphics, Wang tiles are used as a tool to generate non periodic textures and patterns. We develop a framework and a method for the tiling problem which is suitable for applications. In particular, we apply our methodology to a special kind of Wang tiles, called Brick Wang tiles, introduced by Derouet-Jourdan et al. in 2015 to model wall patterns. We generalise their result by provi...

This paper deals with the packing of square tiles of the same size into one texture. Texture size is constrained by the graphics hardware. In particular, width and height resolutions must be powers of two. To cover the whole texture and avoid space loss, common schemes pack a number of tiles that is a power of two. We show that numbers of tiles like 5, 13, 17, 25, 34 and others can also be reac...
