“…Goldschmidt (cited in Purcell and Gero 1998) argued that sketching provides a particularly effective procedure for dealing with such tasks and the various aspects of the design process. Lim et al (2003) suggested that, with the universal use of the computer as a design tool, there is a need for a computer-aided sketching system. Using nine designers of various experience they developed a free-form modelling system from online sketching.…”

“…Basing on initial tests and past studies [34], it is possible to state the CAD modelling process in a virtual reality environment can be improved by introducing helping tools for the data visualization, the geometries modification, the models creation, etc. For this reason we have implemented some of these functionalities in VirDe.…”

Virtual reality (VR), even if it does not represent any more a novel technology, is one of the most powerful tool to help designers during the development of new projects. This is proved by very numerous research activities related to this field. In this research, we have studied a new way to approach the development of a product. We present the ongoing development of a system, called VirDe, acronym of virtual design, which can allow the designers to perform the whole design process, from the modelling phase to the finite element method (FEM) simulation analysis, in a virtual reality environment. This new method allows remarkable time and money saving in the overall product design process, but the most important contribution of VirDe is that, as far as we concerned, there is no known similar approach which has been studying the simultaneous combination of CAD, FEM and virtual environment (VE).

“…In this sense, we must try to remember that visualisation is essentially a cognitive activity, which is not reliant on computers. Recent research by a range of authors ( ( Lim et al , 2004 ), ( Sener and Wormald, 2008 ), for example) has successfully studied the relationships between the professional, medium and the resultant visualisations. Such studies have shown that the approach taken to visualisation itself can affect the insights drawn, and that care should be taken to match the visualisation method (for example, sketching, CAD, 3D modelling, physical modelling, painting and so on) to the desired and intended purpose of the exercise.…”

Since 1999, he has led and participated in a number of research commissions, including ' Streetscapes ' , ' Greenspace ' and ' Urban Connections. In addition, he has recently led research and development projects for the Department of Health, the ESF and Interreg ERDF, as well as participating as a co-investigator on work supported by the ESRC. He represents the RICS on the European Construction Technology Platform, with a particular emphasis on energy effi ciency in buildings. Jonathan Scottcompleted an HND in Architectural Technology in 1992, followed by a degree in Architectural Technology, graduating in 1998 with a fi rst-class award. Supported by an EPSRC studentship, Scott undertook a PhD, completed in 2004, in the fi eld of environmental design, creating a decision-making tool for the selection of detached homes. Except for a short stint in industry, he has worked in research and teaching, developing his interests in the areas of environmental design, energy monitoring, life-cycle analysis, social and occupancy evaluation. In addition, he is also interested in CAD, surveying technologies and historic conservation. Scott is a course leader in Architectural Technology at RGU.Correspondence: Richard Laing , The Scott Sutherland School of Architecture and Built Environment, Robert Gordon University, Garthdee Road, ABERDEEN AB10 7QB, UK E-mail: r.laing@rgu.ac.uk ABSTRACT This article discusses the use of high-defi nition 3D scanning in the recording and modelling of the built heritage. In particular, it explores how such technology can be used as a complement to both traditional measurement and historic records, as well as in the 3D surface modelling of heritage detail. The article uses examples from cinema buildings of the twentieth century, which arguably embody both an important physical record of society and a challenge in terms of representing a complex range of historical, cultural, economic and physical data sets. The work provides an overview of visualisation techniques that are appropriate to the subject, and provides a case study taken from the city of Aberdeen. In particular, attention is drawn towards the manner in which large and physically complicated structures can be recorded rapidly, to provide a permanent record of dimensions and building form. Furthermore, the data set produced through use of a 3D scanner can be readily translated for incorporation within architectural models such as a 3D surface mesh. The article concludes that emerging technologies will facilitate the rapid collection of highly accurate information pertaining to the still intact physical structure, where still in place, but that such data must be related directly to wider contextual information so that informed plans can be formulated for future developments, including conservation strategies.
