The application of 3D modelling techniques in built environment evaluation

This paper describes a series of methodologies for use in evaluation of the built environment. The use of virtual models within Architecture and Engineering is widespread at the design stage, but has to date been limited in terms of application and interaction when evaluating the impact of designs on existing environments. Methodologies already established in other fields including environmental protection and retail were applied, to establish whether such methods were appropriate for use in the built environment. These methods, although theoretically established, have previously tended to rely on text-based scenarios, effectively causing great difficulties for research where the aesthetic impact of changes may be key to decisions to be taken. A series of virtual models of existing areas were constructed within CAD and 3D Studio, providing a realism of sorts and the ability to manipulate the environment reasonably rapidly. Through the use of both online and onsite experiments, the capabilities of CAD style models within such experiments was tested fully, and positive results generated. The research noted that 3D models have been used only rarely to facilitate real interaction between interested or affected parties. Currently available software, designed primarily for gaming, is capabl
