Example-based modeling is an active line of research within the computer graphics community. With this work we propose a re-targeting scheme for polygonal domains containing a layout composed of discrete elements. Retargeting such domains is typically achieved employing a deformation to the initial domain. The goal of our approach is it to compute a novel layout within the deformed domain re-us...

Driven by the prospect of three-dimensional rasters as a primary vehicle for future 3D graphics and volumetric imaging, this paper introduces an architecture for real-time rendering of high-resolution volumetric images. The Flipping Cube Architecture utilizes parallel memory organization and a unique data orientation scheme in order to support contention free access to viewing rays. The swift a...

Graphs, node-link diagrams, are frequently used to visualize structured information. But while much work has gone into methods for visualizing single graphs, it is still an open question how to visualize multiple graphs to best convey their structural and semantic similarities and differences. We present a visualization technique for comparing graphs. At its core, our method is a graph layout a...

Situational awareness is defined as the ability to effectively determine an overall computer network status based on relationships between security events in multiple dimensions. Unfortunately, as the lack of tools to synthetically analyze the security logs generated by kinds of network security products, such as NetFlow, Firewall and Host Security, it is difficult to monitor and perceive netwo...

Recognition of geometric primitives such as line and arc helps in automatic conversion of line drawing document images into electronic form. A large number of raster to vector methods can be found in the literature. A line and arc segmentation contest was held in conjunction with the tenth IAPR International Workshop on Graphics Recognition (GREC 2013) for comparing performance of different met...

The eeective visualization of hierarchical structures is an important problem in the area of advanced visual interfaces. Hierarchical structures occur in a wide variety of visualization applications, including WWW-A hierarchical structure can be formally modeled by a directed acyclic graphs (DAG), i.e., a directed graph with no directed cycles. Hence, throughout this abstract, we will use the t...

We present a fast parallel algorithm for layout of undirected graphs, using commodity graphics processing unit (GPU) hardware. The GLUG algorithm creates a force-based layout minimizing the Kamada Kawai energy of the graph embedding. Two parameters control the graph layout: the number of landmarks used in the force simulation determines the influence of the global structure, while the number of...

A quasi experimental study was done to determine significant positive effects among three different types of visual models and to identify whether any individual type or combination contributed towards a positive increase of spatial visualization ability for students in engineering technology courses. In particular, the study compared the use of different visual models a 3D printed solid object...
