Abstract

Rendering high-definition 3D models is becoming a commonly requested task for scientific simulation, visualization and computer graphics. Many research areas generate extremely complex 3D models, such as industrial CAD models (e.g. airplanes, ships and architectures), composed of more than hundreds of millions of geometric primitives. However, these complex datasets cannot be rendered efficiently using brute-force methods on a desktop workstation. Desktop computer technology has recently reached a point where it has advanced sufficiently to calculate and process a number of photographs of an object from different perspectives to produce an accurate three-dimensional (3D) high-definition digital model. This project explores the potential applications of 3D digital models in terms of extracting complex geological data. Different methods of data acquisition and the scale of outcrops are compared between difficult to access rock outcrops in a remote High Himalayan region of Photoksar, Ladakh to more accessible, low lying coastal areas on the NSW South Coast at Bingie Bingie Point, Narooma, Wolumla and Eden. Archaeological sites and ultra-high resolution aerial photographs are also applied to the methods outlined. The application of photogrammetry at each site is assessed and compared to determine the benefit of it is applicable in any or all regions. The methods are assessed for efficiency, convenience and relevance of extracting complex structural geological data with emphasis on developing the highest quality digital 3D models possible. Any data extracted is tested for accuracy by comparing it with structural geological measurements obtained on the field by traditional methods using the trusted Field Move mobile application as a compass and clinometer equivalent. The results aim to provide a reliable and informative source of information outlining the methods used, what equipment is needed and what information can be extracted.
