Efficient and realistic rendering of knitwear is of great interest especially in the context of ecommerce. Computing geometry play key role in the generation of realistic images, and also has important application in real-time rendering. This paper presents a method for rendering realistic knitwear. Triangles are used to subdivide the yarn surface so that graphics can be obtained quickly and ef...

In this paper, we summarize our results on a variant of the Ants Nearby Treasure Search (ANTS) problem, where n mobile agents, controlled by asynchronous randomized finite automata, search collaboratively for a treasure hidden by an adversary. We show that despite these restrictions, the treasure can be located in an optimal run-time of O(D + D2/n). Moreover, we consider slight variations of th...

Pedestrian navigation is a complex function of human dynamics, a desired destination, and the presence of obstacles. People cannot stop and start instantaneously and their turning abilities are influenced by kinematic and dynamical constraints. A realistic model of human walking paths is an important development for entertainment applications and many classes of simulations. We present a novel ...

In the construction of 3D site models, much more emphasis has been put on the creation of the 3D shapes than on their textures. Nevertheless, the overall visual impression will often depend more on these textures than on the precision of the underlying geometry. The paper proposes a hierarchical texture modeling and synthesis technique to simulate the intricate appearances of building materials...

The vast majority of previous research of snow in computer graphics has been on the construction of relatively high level geometric descriptions. Indeed this is not unreasonable, as it is the most salient visual characteristic of snow, however, a large number of visual cues come from the surface appearance of snow: its density, purity, cues to curvature and thickness. These cues are essential t...

The goal of this deliverable is the development of applications in collaboration with Working Group A2 “Bioinformatics”. Some such applications of reactive web frameworks and languages developed in I5 have been made. In particular, using the r framework we have developed two applications in close collaboration with A2 members: the B-Domain application and the PubMed Reactive Classifier. Other a...

Physically correct and realistic visual appearance rendering or analysis of material surface visual properties require complex descriptive models capable of modelling material dependence on variable illumination and viewing conditions. While recent advances in computer hardware and virtual modelling are finally allowing the view and illumination dependencies of natural surface materials to be t...

The depiction of the irregularity in nature is crucial for the realistic representation of the real world. For example, real pavement blocks are not always paved evenly, but partially sink over time. Many games or virtual reality systems however represent the pavement too neatly with perfectly flattened surface and clean texture images. In this paper, we suggest a method for representing realis...

s and PDFs, which is full-text searchable and seamlessly linked to PubMed, is a free resource for the scientific community, and indeed to the world at large. It represents generations of the finest work in cell biology, and an unparalleled history of how our field grew from a curiosity to the most central body of knowledge in all of biology and biomedical science. It also demonstrates how the f...
