In the paper, we propose an automated, SVG-based visualization framework for modeling languages defined by metamodeling techniques. Our framework combines XML standards with existing graph transformation and graph drawing technologies in order to provide an open, tool-independent architecture.

In this paper a process visualisation development system and its associated development methodology are presented. This methodology is optimised to systems that have complex structure and are built of large number of components belonging to relatively small number of types. In order to handle the complexity, the input requirements of the method is as close to the ”native language” of the applic...

In January 1993, we received NSF funding to develop a pre-graphics course for freshman engineering majors who are weak in 3-D spatial visualization skills. A text and computer lab exercises utilizing I-DEAS software were written specifically for this course. The course is 3-credits (quarter system) with two hours of lecture and two hours of computer lab each week. It was offered at Michigan Tec...

This paper presents a novel approach for recognizing and interpreting dimensions in engineering drawings. It starts by detecting potential dimension frames, each comprising only the line and text components of a dimension, then verifies them by detecting the dimension symbols. By removing the prerequisite of symbol recognition from detection of dimension sets, our method is capable of handling ...

Virtual worlds exploration techniques are used in a wide variety of domains — from graph drawing to robot motion. This paper is dedicated to virtual world exploration techniques which have to help a human being to understand a 3D scene. An improved method of viewpoint quality estimation is presented in the paper, together with a new off-line method for automatic 3D scene exploration, based on a...

At the heart of every good graph drawing algorithm lies an efficient procedure for assigning canvas positions to a graph’s nodes. However, any real-world implementation of such an algorithm must address numerous problems that have little to do with the actual algorithm, like handling input and output formats, formatting node labels, or styling nodes and edges. We present a new framework, writte...

One of the skills that all engineering professional must develop very extensively during their formation is the mental management of the three dimensional reality in which they develop their professional actions. This competence is called spatial skill, a cognitive skill which can be improved with proper training. We have developed a series of learning activities for students in order to acquir...

Abstract. When adjusting a graph layout, it is often desirable to preserve various properties of the original graph in the adjusted view. Pertinent properties may include straightness of lines, graph topology, orthogonalities and proximities. A layout adjustment algorithm which can be used to create sheye views of nested graphs is introduced. The SHriMP (SimpleHierarchicalMulti-Perspective) vis...

We present a simple, general-purpose tool for visualising Java data structures. The tool uses Java reflection and an open-source graph drawing program to produce text-book quality depictions of arbitrary Java objects. The tool offers certain pedagogical advantages over other “heavy-weight” visualisation systems. Its simplicity and generality means that students are able to visualise their own d...

Hyperlinks among webpages are very important information and are widely used for webpage clustering and webpage ranking. With the explosive growth in the number of webpages available online, the exploration of hyperlinks among webpages becomes a very challenging problem. Information visualization provides an effective way of visualizing hyperlinks and can help users gain insights into the relat...
