Developing a standard process for visualizing CFD simulation results
With the use of modern simulation processes and high performing hardwa-
re the amount of simulation data to be analyzed is increasing while time for
development is reduced. Thus the engineers need an instrument to analyze
complex ﬂow phenomena. The software COVISE can be used to visualize si-
mulation data in a Virtual Reality (3D stereo) environment. In this thesis a
description is given for the integration of COVISE into existing data-processes
and the changes for this software for the use at the Daimler AG infrastructure.
The document is split into three parts.
The current state of the art for visualization techniques and a small introduc-
tion to COVISE is given in the ﬁrst chapter. Furthermore, important data-
formats used at Daimler AG like BIF/BOF, PLMXML, JT and STL are spe-
The second part contains information about current data-processes to set up
ﬂow-simulations for the truck-division. The data-allocation, data-conditioning
and the simulation itself are explained. Additionally there is a short descripti-
on of the software tools in use.
The third chapter is addressed to modiﬁcations and extensions of COVISE con-
cerning the Daimler AG requirements. Implemented functions are introduced,
and the programming-approach is shortly described. There is the "LoadCAD" module to read CAD-data, the OpenCOVER plugin "Coordsystems" for vi-
sualization of coordinate systems, the COVISE module ReadBIFBOF“ to
parse the Medina data-format and the PLMXML "plugin". This plugin was
enabled selectively loading of data, referenced in PLMXML-ﬁles, and to couple
simulation- with CAD-data. Also, three options are given for implementing a
visualization process into the Daimler data structure: "Datenmanagement über
PLMXML-Dokumentation“, "Zentrale Berechnungsdatenbank“ and "Zentrale
Workbench are these three solutions. Closing remarks show the future pro-
spects for the implementation of VR into the development process.
Simulation of 3rd party vehicles
3rd party vehicles are an essential part of a driving simulation environment. In order to support autonomously driving vehicles, the road system has to be described in all aspects such as driving lanes, junctions , traffic lights, signage and so on.
Vehicle agents are then driving on these roads based on physical constraints, simulated driver behaviour and interaction with other autonomous vehicles and human drivers.
Model and Imagination
The importance of representation in architecture and virtual models
The theory of "Virtual Complementation" describes the necessity for a mutual complementation of the virtual and the real. The physical architectural model functions as fundamental model, that means as an entré point in the playful act of imagination. As support the virtual model offers some more stimulation and augments the fundamental architectural model. While the virtual model enables the user to put themselves into the model, the real model creates a connection back to the physical reality. Together they build a starting point for the playful and innovative combination of imaginations. The physical and the virtual model are connected to each other, both with their own benefit, but also with new ones coming from this interconnection The aim is to point out that virtual stands for opportunities, coming from the individual connection cord of these two models, the user's imagination.
Mixed Reality Tanztheater
Scenario for new technologies in the Tanztheater
The Mixed Reality Tanztheater links the real world and the virtual world. In a real world auditorium spectators wear Augmented Reality Interfaces so that they can experience parallel plots, telepresence and virtual spacial events.They become directors of their individual perspective.
Through a linked installation of CAVE (VR) and an Augmented Reality (AR) one can immerse into the scenario and interact with others.

raum.art is the architectural approach to the question: do virtual electronic space needs a museum? the architectural form is characterized by the specific properties of the virtual space. the raum.art museum is a meta-structure for experimental objectrooms, where users can interact and percept electronic art-pieces.
Virtual Architectural Library
The subject of this work is to arranged a virtual library, which should be the correct answer to the fast changes and the new way of thinking into our time.The virtual library should be an efficient interface, between the visitor and a data base.

Processes at the stock exchange steadily create enormous amount of data. In the current situation this often results in permanent stress situations for the broker and a climate full of irrational decisions.
Brokers delight visualizes and organizes the information spatially in an artificial immersive environment. Making use of the potential of human perception and his experience of acting in a three-dimensional world the broker is offered an intuitive way of accessing, analysing and deciding responsibly in complex situations overloaded with information.
brokers delight - an observe'n'decide tool for a virtual stock exchange.
homebase consists of 4 environments to fulfill the users needs
to access geographical based information
to access user specific information
- to meet friends
the interaction navigation and orientation in these environments change according to each funcion.
