New article – Interactive Landscape Relighting

I have just published a short article, co-written with Paul Cripps, entitled Interactive Landscape Relighting in the Remote Sensing and Photogrammetry Society’s Archaeology Special Interest Group Spring 2011 Newsletter. It is a summary of the work I have been doing on scaling virtual Polynomial Texture Mapping techniques up to allow us to examine whole landscapes […]

A sample of the Stonehenge WHS LiDAR PTM, which you can illuminate from any direction

Virtual lights, 3D terrains and a bit of Stonehenge

I have just published a blog post on the Wessex Archaeology website entitled Interactive Landscape Relighting. It is about using Polynomial Texture Mapping (PTM) in a virtual environment, using LiDAR (airborne laser scanning) to create models of landscapes which can be illuminated by the viewer from any angle.   The post uses part of the […]

Imaging the Antikythera Mechanism

The Antikythera Mechanism is thought to be a 2nd/1st century BC mechanical device for calculating astronomical positions (and thus a very advanced navigational device of its time). It was made somewhere in the Greek-speaking world. Tom Malzbender, one of the inventors of Polynomial Texture Mapping (PTM), recently gave a Google Tech Talk entitled “Imaging the […]
