Chapter
Flat roofs have become popular also in central and northern Europe during the last decades. One advantage when compared to pitched roofs is that flat roofs are typically significantly cheaper. Furthermore, the roof space can be used also as a garden, a terrace or simply to quite easily install photo-voltaic systems on it. However, flat roofs are kn...

The Coronavirus Disease 2019 (COVID-19) has shown us the necessity to understand its transmission mechanisms in detail in order to establish practice in controlling such infectious diseases. An important instrument in doing so are mathematical models. However, they do not account for the spatiotemporal heterogeneity introduced by the movement and i...

With the rise of virtual reality experiences for applications in entertainment, industry, science and medicine, the evaluation of human motion in immersive environments is becoming more important. By analysing the motion of virtual reality users, design choices and training progress in the virtual environment can be understood and improved. Since t...

In industry and science, sensor data play a vital role in research, optimisation, monitoring, testing and many other use cases. When performing tests with repeated cycles of similar behaviour, e.g., durability tests, it is often important to find anomalous sensor behaviour that deviates from regular patterns in the data. We here explore the design...

In the context of computer-aided design, computer graphics and geometry processing, the idea of generative modeling is to allow the generation of highly complex objects based on a set of formal construction rules. Using these construction rules, a shape is described by a sequence of processing steps, rather than just by the result of all applied op...

Conference Paper
The Automated Cruise Control (ACC) automatically accelerates the vehicle to reach a set speed, maintains the set speed and decelerates to maintain separation from a forward driving vehicle. For the data presented in this poster the average speed was 100 km/h (62 mph) and the time gap was 1 second. The automated control actions of an (ACC) system we...

This tutorial introduces the concepts and techniques of procedural & generative modeling. It starts with some introductory examples to motivate the main idea: to describe a shape using an algorithm. After the explanation of technical terms, the second Section focuses on technical details of algorithm descriptions, programming languages, grammars an...

The idea of generative modeling is to allow the generation of highly complex objects based on a set of formal construction rules. Using these construction rules, a shape is described by a sequence of processing steps, rather than just by the result of all applied operations: Shape design becomes rule design. Due to its very general nature, this app...
Conference Paper
Delivering high quality 3D content through a web browser is still a challenge especially when intellectual property (IP) protection is necessary. Thus, the transfer of 3D modeling information to a client should be avoided. In our work we present a solution to this problem by introducing a server-side rendering framework. Only images are transferred...
Conference Paper
Procedural modeling techniques can be used to encode a geometric shape on a high and abstract level: each class of objects and shapes is represented by one algorithm; and each artifact is one set of high-level parameters. In this article, we use a generative object description and register it to real-world data e.g. laser scans. Afterwards, we can...

Fahrerassistenzsysteme haben in zahlreichen Studien ihr Potential zur Vermeidung von Verkehrsunfällen bzw. deren Folgewirkung gezeigt. Aktuell werden zunehmend mehr Fahrzeugklassen beginnend von der Oberklasse bis zu Kompakt- und Kleinwagen mit unfallvermeidendenden Systemen ausgestattet. Fahrerassistenzsysteme wirken immer in Zusammenarbeit mit de...
Conference Paper
In this paper we present a novel method to evaluate guidance systems and navigation solutions for public infrastructures based on an immersive virtual environment in combination with a mobile eye tracking system. It opens new opportunities for wayfinding studies in public infrastructures already during the planning phase. Our approach embeds an int...
Conference Paper
Semantische Informationen, die ein Objekt auf einem hohen, abstrakten Niveau beschreiben, sind erforderlich, um Bibliotheksdienste wie Indizierung, Markup- und Retrieval anzubieten. Im Zeitalter digitaler Medien sind entsprechende Algorithmen und Techniken zur Erfassung textbasierter Objekte etabliert: Volltextsuche, automatische Verschlagwortung u...
Article
Within the last few years, generative modeling techniques have gained attention especially in the context of cultural heritage. As a generative model describes a rather ideal object than a real one, generative techniques are a basis for object description and classification. This procedural knowledge differs from other kinds of knowledge, such as d...
Conference Paper
Scripting languages are easy to use and very popular in various contexts. Their simplicity reduces a user’s threshold of inhibitions to start programming – especially, if the user is not a computer science expert. As a consequence, our generative modeling framework Euclides for non-expert users is based on a JavaScript dialect. It consists of a Jav...

The need to analyze and visualize differences of very similar objects arises in many research areas: mesh compression, scan alignment, nominal/actual value comparison, quality management, and surface reconstruction to name a few. In computer graphics, for example, differences of surfaces are used for analyzing mesh processing algorithms such as mes...
Conference Paper
Normal maps and bump maps are commonly used techniques to make 3D scenes more realistic. Consequently, the efficient storage of normal vectors is an important task in computer graphics. This work presents a fast, lossy compression/decompression algorithm for arbitrary resolutions. The complete source code is listed in the appendix and is ready to u...

In the context of computer graphics, a generative model is the description of a three-dimensional shape: Each class of objects is represented by one algorithm $M$. Furthermore, each described object is a set of high-level parameters $x$, which reproduces the object, if an interpreter evaluates $M(x)$. This procedural knowledge differs from other ki...

Offering an easy access to programming languages that are difficult to approach directly dramatically reduces the inhibition threshold. The Generative Modeling Language is such a language and can be described as being similar to Adobe's PostScript. A major drawback of all PostScript dialects is their unintuitive reverse Polish notation, which makes...

Procedural modeling is a technique to describe 3D objects by a constructive, generative description. In order to tap the full potential of this technique the content creator needs to be familiar with two worlds - procedural modeling techniques and computer graphics on the one hand as well as domain-specific expertise and specialized knowledge on th...

Project
The goal of the research project VR4CPPS (Virtual Reality for Cognitive Products and Production Systems) is to improve development, production and operation of complex production and test systems by early integration of Virtual Reality (VR) technology. We focus on the improvement of the design quality by enhanced cross-team collaboration methods, and on improvement of production efficiency by VR-based training of technicians for new production lines. Furthermore, we focus on the reduction of after-sales efforts through the development of virtual spaces for efficient collaboration of experts and operators during operation and maintenance activities.

Project
The primary objective of this K-Project is to provide an integrated platform for the automation of engineering design tasks. The platform will consist of a conceptual framework, including generative methods and algorithms for design automation as well as a software framework based on the implementation of those methods. Additionally, it will include methods for knowledge acquisition as to the rules and procedures used by domain experts during the engineering design process. Metrics for a-priori as well as a-posteriori cost-benefit assessment of particular automation projects will round off the project deliverables. The results of the project have been evaluated and benchmarked in real-world test-beds defined by the industrial partners. Website: www.aeda.at
