Polynomial Texture Mapping at Roughting Linn Rock Art Site
نویسنده
چکیده
This study tests the feasibility of using Polynomial Texture Map (PTM) recording technology at Roughting Linn rock art site. Additionally, it examines the added value of incorporating PTM into the existing record of the rock carvings. Finally, it explores the application of PTM as a tool to enhance the understanding of cultural significance of the ancient site. A Polynomial Texture Map (PTM) is an interactive file comprised of a compilation of multiple digital photographs generated using Reflection Transformation Imaging (RTI), an image-based recording method in which information about surface reflectance is captured per pixel. This project demonstrated that PTM technology is a feasible documentation tool in terms of cost and adaptability to a remote rock art site such as Roughting Linn. Additionally, it demonstrated the added value of including PTM information in the existing record of the carvings. Finally, there are indications that incorporating PTM into the record of rock carvings can enhance the understanding of cultural significance of the ancient site.

Polynomial Texture Mapping and Related Imaging Technologies for the Recording, Analysis and Presentation of Archaeological Materials
Polynomial Texture Mapping (Malzbender et al., 2000, 2001) uses multiple images to capture the reflectance properties of a given surface. Multiple captures may be combined in order to produce interactive, relit records of the material sampled. Cultural heritage examples of the technology include work on cuneiform tablets, numismatic archives and lithic artefacts. This paper introduces the PTM d...
متن کاملNew Reflection Transformation Imaging Methods for Rock Art and Multiple-Viewpoint Display
We offer two new methods of documenting and communicating cultural heritage information using Reflection Transformation Imaging (RTI). One imaging method is able to acquire Polynomial Texture Maps (PTMs) of 3D rock art possessing a large range of sizes, shapes, and environmental contexts. Unlike existing PTM capture methods requiring known light source positions, we rely on the user to position...
متن کاملDigital recording of aboriginal rock art
A technique to digitally document and thereby permanently preserve prehistoric rock art has been developed. Laser scanning and texture mapping from digital images were used. Methods involving texture mapping require the exact relationships between the image and geometrical sensors. For geological structures, such as caves, the distinctive features required for registering the texture with the g...
