Interactive Landscape Relighting

There’s a short article in the Remote Sensing and Photogrammetry Society’s Archaeology Special Interest Group Spring 2011 Newsletter looking briefly at how archaeologists can investigate landscapes using digital techniques, co-authored by Tom Goskar and myself. Using Reflectance Transformation Imaging (RTI) techniques it is possible to look in detail at surface morphology of Digital Surface Models (DSMs) by creating Polynomial Texture Maps (PTMs) representing parts of or even entire landscapes which can then be dynamically relit, a process Tom has named Interactive Landscape Relighting.
