This paper discusses the advancements in preserving historical and architectural heritage through 3D modeling, focusing on the reconstruction of models from photographs using the Daedalus software system developed by the University of Manchester. It compares traditional methods such as laser scanning with newer techniques that utilize computer vision, highlighting the trade-offs between accuracy and cost. Additionally, the paper explains the use of illumination algorithms in enhancing visual fidelity by applying techniques like texture mapping and displacement mapping.
