The purpose is to translate the client's specifications into a shape as automatically as possible. However, the processing of a text in natural language is still out of reach. We then assume that the client's specifications are manually translated into intermediate specifications composed of intermediate constraints upon physical parameters. Our efforts concern the transformation of these intermediate specifications into a shape, precisely the way to complete whether a shape satisfies the intermediate specifications or not. We first study the case in which the shape is a single primitive solid; we also give elements to choose the instance that best fits the specifications. Then, we study the extension of the method to solids defined by a combination of primitive solids.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

Concurrent engineering can provide a highly effective framework for this collaboration. A distributed object oriented concurrent engineering system (DISCS) focuses on the communication of data between the members of a distributed project team. Conceptually the communication is the enabling factor; technologically the use of the WWW and object oriented technologies. A portfolio of collaboration support tools facilitates practical mechanisms for information sharing within the distributed enterprise, communication/conferencing for project teams, configuration/version control and workflow structures. DISCS effectively facilitates the virtual team, currently within an engineering context.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

Currently, three dimensional rendering hardware are facing a memory bus bandwidth bottleneck problem at the graphics pipeline. One general solution for this problem is to compress the static three dimensional geometry in a preprocessing phase. We present a new mesh compression/decompression algorithm for this application. Our compression algorithm breaks down a triangle mesh into a set of triangle strips and vertex chains. After decomposition, we encode vertex connectivity with entropy encoding. Our algorithm provides a 32% improvement in the compression ratio over existing \"Generalized Triangle Mesh (GTM)\" compression and supports parallel decompression. We also proposed a parallelogram prediction method for vertex coordinate compression.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

In the first wave, GIS functions have been built into engineering applications, which were not just GIS centered (as for example road design, emission calculation, building site-plan etc.). The use has been accelerated through the component technology, which simplifies the insertion of GIS components into a variety of applications-including administration. We describe the upgrading of the business information system of the Slovenian road administration: basic application user interfaces were enriched with a specialized GIS component, which enables a fast and clear (geo)graphical view of the data about the selected part of the road network. The simplicity of using this intelligent digital map (as we named this specialized component) makes it possible to effectively and clearly display the relevant information, which is so necessary in the process of decision making. Besides, there is no need to leave the application the user is familiar with.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

A potentially valuable means of ameliorating this difficulty is to use metaphors to aid the user as they interact with the system. The value of metaphors in overcoming the problems of cognitive overloading and navigational overhead is discussed and an experimental study proposed to investigate the design and deployment of suitable metaphors in this context.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

He argues that if he does kill him, Claudius who is praying at that very moment goes to heaven and if he does not kill him Hamlet's father is not revenged. A contradiction. Ultima Ratio aims at formalization and visualization of argumentation for agents. An agent is constituted by a set of arguments and assumptions. Facing a particular world, the agent's believes may be inconsistent triggering a rational monologue to deal with the situation. Formally, we define a framework for argumentation based on extended logic programming under well-founded semantics. The system serves as decision support and is capable of detecting and removing contradictions and deriving conclusions of the agent's arguments. To demonstrate the structure and dynamics of the agent's argumentation, we visualise the process as dynamic construction of proof trees. The paper includes screenshots of the logical engine and the visualisation unit as exhibited at the computer arts exhibition Ars Electronica 98.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.

Given the large number of different Web sites providing listings, each with its own presentation format, and the high dimensionality of the property space itself, it is difficult to obtain a comprehensive single view of property data on the Web. ReV addresses this problem by using grammar induction techniques to automatically learn to parse pages from new Web sites and collate all of their listings together. It them visualizes this listing data using a map based color coding technique. This work draws together a number of strands from the fields of information visualization, machine learning, and database integration. We also hypothesize that ReV will be adaptable to inducing structures from other types of Web data.","PeriodicalId":340240,"journal":{"name":"1999 IEEE International Conference on Information Visualization (Cat.
