An octree-based implementation of directional operators in a 3D spatial query language for building information models

Abstract: In a current research project, our group is developing a 3D Spatial Query Language that enables the spa-tial analysis of Building Information Models and the extraction of partial models that fulfil certain spatial constraints. Among other features, the spatial language includes directional operators, i.e. operators that reflect the directional relationships between 3D spatial objects, such as northOf, southOf, eastOf, westOf, above and below. The paper pre-sents in-depth definitions of the semantics of these operators by means of point set theory. It further gives an overview on the possible implementation of directional operators using a new space-partitioning data structure called slot-tree, which is derived from the objects’ octree representation. The slot-tree allows for the application of recursive algorithms that successively increase the discrete resolution of the spatial objects employed and thereby offer the possibility for a trade-off between computational effort and required accuracy.

Design studio of the future

Abstract: New communication media enable new design technologies. To investigate the mutual influenceof a new medium like Virtual Reality (VR) and architectural design technologies, a laboratorycalled 'the design studio of the future' is established. In due time a design system will bedeveloped offering different design technologies in an integrated environment. Interfaces withinVR will support various approaches to the design problem. A large research program (VirtualReality - Distributed Interactive Systems) is carried out to provide state-of-the-art tools fordesigners to experiment and to give feed back on the results.

Dynamic information system for modeling processes

Abstract: DINAMO is a dynamic Information System for Modeling of Design Processes. It is intended for use along with product models, data management systems and existing applications. In DINAMO a programming user can define processes. These processes are represented by graphs. The graphs are characterized by nodes and relations between nodes. Each node in a graph represents a task, and each relation can be restricted to conditions. So the way in which a process is actually been performed, that is the actual path to be evaluated through the graph, can depend on certain conditions. Processes and functions (= software modules) are available to the user as tasks. A consuming user can activate tasks; the DINAMO system regulates the dispatch of the tasks, conform the process and function definitions. Tasks are collected on sheets; sheets are collected in a task box. A task box can be regarded as a certain environment, determined by the programming user. A consuming user can choose between the environments which are available at that moment. With the DINAMO system software and process definitions can be re-used in a simple way.

IT education and utilization within the upcoming shared master of science in construction management and engineering in the Netherlands

Abstract: In March 2004, the Task Force Sector Plan presented their final report to the State Secretary of Educa-tion, Culture and Science. In this report, the three universities of technology (3TU) proposed how they aim to create a single federation of Dutch universities of technology by combining their education and research programmes in order to enhance knowledge valorisation. In addition, five shared Master of Science (MSc.) programmes - not yet offered in The Netherlands but considered to be essential for the Dutch knowledge economy - were proposed, including the MSc. Construction Management and Engineering (CME) programme. The MSc. CME programme, realized at the three 3TU locations, consists of two blocks: (1) a general block and (2) a specialization block. The general block covers the topics that provide a sound basis for further specialization at one of the three locations of the 3TU. Within the general block – but moreover in the specialization block offered in Delft – contains a large amount of IT education and utilization. This paper will discuss the overall programme of MSc. CME programme and the development process of the MSc. CME specialization in Delft, with a special emphasis on the IT related subjects.

Feature type recognition - implementation of a recognizing feature manager

Abstract: This paper reports the first phase of a research project to implement and apply Feature Type Recognition (FTR). This technology has many potential areas of application, such as case retrieval, product finding, translating models between schemas, and certain types of analysis. Feature Type Recognition is part of the Internet based design knowledge sharing system developed at the authors' department. The system allows communication of highly abstract concepts as well as concrete data. Additionally, it supports a layered approach to modelling, which will facilitate standardisation efforts. Feature Type Recognition is the process of finding feature types that correspond to a specific feature instance. The paper shows how feature based modelling creates a foundation for feature type recognition. Additionally, it presents and discusses how the Recognizing Feature Manager has been implemented. Application of Feature Type Recognition to building product finding will take place in the second phase of the research project. However, the paper already discusses basic principles of how this can be done.
