This thesis investigates the use and potential applications of emerging 2.5D and 3D digital technologies applied to the study, conservation and presentation of the surface texture of paintings concentrating particularly on issues and applications relevant to the National Gallery in London and its collection. The first part of the thesis reviews both 3D and 2.5D methods that have been used to record the surface of cultural heritage objects with particular attention to paintings. The advantages and limitations of using some of these methods is demonstrated on several paintings from the National Gallery and several mock-up paintings prepared specifically to demonstrate their effectiveness against challenging surfaces. The second part of the study proposes a practical workflow to generate photorealistic high-resolution 3D models of paintings. A combination of various imaging methods, software and computer graphics techniques is used to produce highly detailed 3D models that are computationally efficient for online visualisation and real-time interaction. The workflow is demonstrated through a range of case studies with different optical surface qualities and geometric features. The third part investigates the possibility of transferring the high-resolution detail encoded in normal maps to a high polygon mesh that can be used to translate the digital model into a physical reproduction by using a computer numerical control milling machine. Based on the understanding of the conservation needs when dealing with complex restoration treatments, the last section of this research investigates the potential production of custom-made foam supports for paintings that may require cushioning and protection during conservation treatment. This thesis aims to provide practical and user-friendly workflows based on available software and simple hardware setups. This work provides tools and practical solutions to guide the user towards specialist applications that extend standard documentation with 2.5D and 3D recording methods. The different methodologies proposed complement each other and together extend the applications of captured surface texture initially recorded during the documentation stage. |
