This paper presents an interactive technique for the dense texture-based visualization of unsteady 3D flow, taking into account issues of computational efficiency and visual perception. High efficiency is achieved by a 3D graphics processing unit (GPU)-based texture advection mechanism that implements logical 3D grid structures by physical memory in the form of 2D textures. This approach result...

In this research, the influence of bolt preload on the fatigue strength of 2024-T3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. To do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 N-m and then fatigue tests were conducted under various cyclic axial load levels. In the numerical method, th...

This paper describes a volumetric view-merging algorithm that generates a consensus surface of an object from its range images. Our original method merges a set of range images into a volumetric implicit-surface representation, which is converted to a surface mesh by using a variant of the marching-cubes algorithm. We propose a method that increases the computation and memory efficiency for com...

Three-dimensional (3-D) objects are often represented by geometric models in applications dealing with virtual reality, augmented reality, and cyberspace. Surface representations can provide an effective visualization of these objects. Polygonal models are the most prevalent type of surface representation. Recently, multiresolution representation (surface simplification) of polygonal models has...

Volume models often show high depth complexity. This poses difficulties to the observer in judging the spatial relationships accurately. Illustrators usually use certain techniques such as improving the shading through shadows, halos, or edge darkening in order to enhance depth perception of certain structures. Both effects are difficult to generate in real-time for volumetric models. Either th...

Very little is known of the challenges to suspension feeding performance facing early juvenile marine invertebrates, although scaling considerations suggest juveniles are often at a disadvantage. For example, early juvenile ascidians have relatively, as well as absolutely, narrower siphons than later stages, generating high resistance to flow (Sherrard & LaBarbera 2005: Mar Ecol Prog Ser 287:12...

The LiveSync interaction metaphor synchronizes the 2D slice view with the volumetric view to improve the efficiency of diagnosis in the clinical routine. The generation of a meaningful 3D visualization is desirable because often there is not enough contextual information provided by the slice views only. While it is easy to navigate through the slices, the interaction effort to adjust the param...

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...
