We present an adaptively updated Lagrangian Material Point Method (A-ULMPM) to alleviate non-physical artifacts, such as the cell-crossing instability and numerical fracture, that plague state-of-the-art Eulerian formulations ...

This paper discusses the ongoing development of a tool to produce - through an authoring system - an interactive map with advanced functions. A first map has been produced in collaboration with the Municipality of Cetinje ...

O artigo apresentado debruça-se sobre a utilização das novas tecnologias para divulgação e ensino da língua gestual. Embora exista um consenso sobre a necessidade de intervenção humana no ensino de uma língua gestual, ...

Currently, any ordinary user has hundreds or even thousands of electronic documents stored on his computer. Usually, those documents are archived using an hierarchically-organized file system, making their retrieval at a ...

The human figure is important in art. I discuss examples of the abstract depiction of the human figure and the challenge faced in attempting to mimic algorithmically what human artists can achieve. The challenge lies in ...

Existing stroke-based painting synthesis methods usually fail to achieve good results with limited strokes because these methods use semantically irrelevant metrics to calculate the similarity between the painting and photo ...

This paper describes various techniques and applications of rendering three-dimensionally digitized outdoor en- vironments in non-photorealistic rendering styles. The difficulty in rendering outdoor environments is ...

Diffusion tensor imaging (DTI) has been used to generate fibrous structures in both brain white matter and muscles. Fiber clustering groups the DTI fibers into spatially and anatomically related tracts. As an increasing ...

Ray tracing random rays has been a challenge. Due to their reduced coherence, the normal methods of acceleration like packet tracing that make use of coherence of the rays do not work well. These random rays are encountered ...

In this paper, we propose a deterministic simulation of X-ray transmission imaging on graphics hardware. Only the directly transmitted photons are simulated, using the Beer-Lambert law. Our previous attempt to simulate ...
