Models offer researchers an opportunity to view what is left of the remains without the constraints of low visibility, poor lighting, and the partial observations inherent to the excavation process: archaeologists see their sites through layers and trenches. Such models allow visualizations of the data collected from archaeological sites, including shipwrecks. 8.2 Computer-Aided Modelling in ArchaeologyД¬omputer-aided modelling offers archaeological researchers quick 3D images of their reconstructions of the past, and a perspective through which they can analyse archaeological data. Although the development of a procedural model requires skilled computer operators and a significant investment in design, construction, and trouble-shooting, these problems are outweighed by the flexibility offered by the models. Once procedural models are created, they provide both accessible and powerful means for researchers to create and test multiple interpretations of the archaeological data. The results of this project provided evidence of the time-saving effectiveness of a procedural approach to create 3D models as research tools. The resulting model was flexible and versatile, and could be iterated through parametric controls, greatly reducing the traditional change and revision time. To demonstrate this, a procedural model of the lower hull of a sixteenth-century European merchant ship was developed through an iterative process of prototype implementation. The strategy is an approach that leverages computer-based modelling, both parametric- and rule-based. The goal of this project was to reduce the large investment of time and expertise that is currently required to create 3D reconstruction models for nautical archaeological research using typical modelling methods. Justus Cook ( 2012) created a parametric computer model of an Iberian nau or nao hull, and varied the main dimensions according to a set of measurements from historical manuscripts, in order to better understand the changes in the hull shapes (Fig. This reconstruction could be viewed using a real-time immersive visualization system (Fig. Audrey Wells ( 2008) created a detailed reconstruction of the Portuguese vessel Nossa Senhora dos MГЎrtires, lost near Lisbon in 1606, following a hypothetical reconstruction (Castro 2003, 2005, 2009 Castro et al. From the model, developed in Rhinoceros 3D, Hazlett created, annotated, and illustrated construction diagrams of this ship, and hypothesized a construction sequence (Fig. Alexander Hazlett ( 2007) sought to synthesize the data from various sources on the subject of the Portuguese nau to create a timber-by-timber model, following a manuscript which enumerated the timbers necessary to build a merchantman, or nau da India. Richard Steffy Ship Reconstruction Laboratory (ShipLAB) and the Department of Visualization (VizLab) started a decade ago and since then the two institutions have discussed and developed several projects pertaining to the modelling of archaeological ship remains. The results, which will be discussed, were satisfactory, except for the planking, which is a very complex part of the shipbuilding process and deserves future attention. Then the rules were incorporated into the logic of the procedural modelling algorithm, and the resulting model was changed by using the Belinho 1 shipwreck scantlings. A basic collection of the main timber components of a shipвЂ™s lower hull was defined, and functional rules were created for each timber, based on real-world ship design and construction processes.

The 3D model was created using Houdini, a procedural node-based 3D software package.

To demonstrate this approach, an interactive procedural model of the lower hull timbers of a sixteenth-century European merchant ship was developed through a process of prototype implementation, and an evaluation of the usefulness and effectiveness of the prototypes developed was carried out using the timbers from the hull remains of the Belinho 1 shipwreck, found in Portugal in 2014. This chapter analyses the functionality and applicability of procedural computer-based modelling techniques in the field of nautical archaeology.
