Current visualization technology implemented in the software for 2D sonars used in marine research is limited to slicing whilst volume visualization is only possible as post processing. We designed and implemented a system which allows for instantaneous ...

Rendering tomographic data sets is a computationally expensive task, and often accomplished using hardware acceleration. The data sets are usually anisotropic as a result of the process used to acquire them. A vital part of rendering them is the ...

Graph visualization is a large and still evolving problem area in which new approaches appear. Graphs are often used to represent information that contains relations among data. Visual presentation of graphs aims at better graphs comprehension, however ...

Multiple everyday life situations involve cavity flows. Because of its unstable aspect, this phenomenon represents an issue of the utmost seriousness for physicists. This paper describes the design of a system dedicated to interactive analysis of ...

Visualizing three dimensional flow with geometry primitives is challenging due to inevitable clutter and occlusion. Our approach to tackling this problem is to utilize semi-transparent geometry as well as animation. Using semi-transparency, however, can ...

In this paper, we present design principles for cutaway visualizations that emphasize shape and depth communication of the focus features and their relation to the context. First, to eliminate cutaway-flatness we argue that the cutaway axis should have ...

In this paper, we present three approaches to the best view selection for 3D objects, in order to find the proper combination. The first method is based on geometry and uses the maximum amount of visible vertices. The second method uses the visual ...

Bidirectional Reflectance Distribution Functions (BRDFs) are well-known functions in computer graphics, and these special functions represent the surface reflectance of materials. BRDFs can be viewed as multivariate probability density function (pdf) of ...

We describe a technique to generate the geometry of silhouette and crease strokes in geometry shaders. This allows for single-pass, small-overhead rendering of conventional meshes. We exploit classic triangle adjacency information, but also introduce ...

We present a new real-time importance sampling algorithm for environment maps. Our method is based on representing environment maps using kd-tree structures, and generating samples with a single data lookup. An efficient algorithm has been developed for ...

Methods for procedural modelling tend to be designed either for organic objects, which are described well by skeletal structures, or for man-made objects, which are described well by surface primitives. Procedural methods, which allow for modelling of ...

Creating content is a vital task in computer graphics. In this paper we evaluate a constraint based scene description using a system of multiple-agents known from artificial intelligence. By using agents we separate the modeling process into small and ...

An efficient representation of a polygonal mesh by a signed continuous distance field is the main focus of this work. We compare different approaches to implementing such a representation and choose the most efficient one. Several optimizations to the ...

Virtual museums enable Internet users to explore museum collections online. The question is how to enhance the viewer's experience and learning in such environments. In the Sarajevo Survival Tools virtual museum we introduced a new concept of ...

In this paper, we describe the process of computer-simulated radiation scattering and its use when predicting the result of an actual experiment. The principle of discrete dipole approximation is shortly explained and its runtime is measured in order to ...

In the article an idea for a novel way of mapping of textures onto a surface of 3D model is introduced. Our technique is based on two interlocking mappings. The first one maps surface vertices onto a computed skeleton and the second one maps the ...

This paper deals with detection and recognition of matrix codes, such as the QR codes, in high-resolution images of real-world scenes. The goal is to provide a detector capable of operation in real time even on high-resolution images (several megapixels)...

Since its introduction the watershed transform became a popular method for volume data segmentation. A range of various algorithms for its computation were developed, including parallel algorithms for computation on different architectures. Recently ...

This paper evaluates the suitability of High Dynamic Range (HDR) imaging techniques for feature point detection under extreme lighting conditions. The conditions are extreme in respect to the dynamic range of the lighting within the test scenes used. ...

A GPU-based spatio-temporal reconstruction studio has recently been built at the Computer and Automation Research Institute of the Hungarian Academy of Sciences (MTA SZTAKI). The studio has 13 synchronised, calibrated high-resolution video cameras used ...
