Filmification of methods is a promising concept to find new formats for program and data/knowledge representation. It is also to create a basis for specifying and developing a new generation of programming environments, as well as for introducing new types of educational materials. Within this approach various algorithms are analyzed and represented as cyberFilms where special visual constructs, super-symbols...
This paper presents a novel method to detect an important flow feature, vortices, in the ocean. Our method can detect closed streamlines around vortex cores. Coupled with existing vortex core detection, the entire vortex area, which is the combination of the vortex core and surrounding streamlines, can be detected. A variety of feature extraction methods are presented, and those more pertinent to...
In this paper, we present a versatile and robust model for geometrically complex deformable solids. Our approach can be applied to deformable tetrahedral meshes and to deformable triangle meshes. The model considers elastic and plastic deformation. It handles a large variety of material properties ranging from stiff to fluid-like behavior. Due to the computational efficiency of our approach, complex...
Many methods exist for automatically generating three dimensional models of urban environments at various levels of detail. To improve the realism of these models texture maps are applied to the building facades. This paper focuses on techniques which progress towards the automatic application of textural detail to building facades. In particular attention is paid to residential scenes where buildings...
In this case study, we describe our experiences with implementing a hybrid polygonal and point based rendering system for displaying large data sets. Our reasons for choosing a point based system are explained in detail, together with some notes about the implementation and how it was integrated into a larger environment. We then describe some of the unforeseen problems of using point based rendering...
Vector fields produced by experiments or simulations are usually extremely dense, which makes their manipulation and visualization cumbersome. Often, such fields can be simplified without much loss of information. A simplification method for 3D vector fields defined over tetrahedral meshes is presented. The underlying tetrahedral mesh is progressively simplified by successive half-edge collapses....
The 3D reconstruction based on the video image in real-time is an important problem, such as computer vision, computer graphics. The accuracy of the model is even the center issue of these fields. After considering the polyhedral visual hull (PVH) reconstruction method, this paper introduces a model optimized method based on the image feature points matching. In this paper, we present an algorithm...
