Monuments Visualization: From 3D Scanned Data to a Holistic approach, an Application to the City of Aberdeen

This paper aims to present the process of visualizing historic statues of the city of Aberdeen. 3D laser scanning was the main method utilized to obtain the 3D data, which was then transformed into a series of 3D surface models. A laser scanner typically has a range of over 100m (300m for the equipment used here), and records data to levels of accuracy almost impossible to achieve using ´traditional´ surveying techniques. The data recorded by a scanner takes the form of a ´point cloud´, which can be combined with on-site photographs to build up a realistic and accurate virtual model. The paper concludes with discussion of how such data can be readily transferred into industry-standard Architecture, Engineering and Construction (AEC) models, thus, allowing the compilation of a buildings and monuments ´library´ available to the city council and to the public for future urban projects and city regeneration. It is argued that the ability to incorporate data extracted from 3D scan-based models will promote the easier implementation of the 3D information within digital arts, architecture, structural engineering or other purposes. The paper represents an interesting collaboration between disciplines from architecture and computing, and provides a practical and innovative case study which sits between technical advances, and electronic and visual arts.
