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 […]

Archaeology Blogs

I have just published a list of archaeology blogs that I subscribe to via RSS. I have also created a bundle in Google Reader for those, like me, can’t live without an RSS reader. It seems that blogging has been quietly gathering momentum in archaeology since I first started noticing blogs in 2004, and blogging […]

Reflectance Transformation Imaging (RTI) workshop in Southampton, Feb 2011

It’s a bit short notice, but two one-day workshops are being held at the University of Southampton between 21st and 22nd February 2011, where participants can learn about the Reflectance Transformation Imaging family of technologies – of which Polynomial Texture Mapping (PTM) is a member. The workshops are an excellent chance to learn about RTI […]

Archaeology and the iPad

There has been much talk over the past few weeks over an article on called “Discovering Ancient Pompeii with iPad“. In essence a team from the University of Cincinnati are using iPads to replace paper for much of their fieldwork at Pompeii. From email lists, to archaeology and popular tech blogs, the news has […]

Past Thinking moves server and house

Past Thinking has just moved to a new server. Please excuse us as we re-set the site back up. The reason for the move is because we had been hacked, and search results for posts on this site showed up as pharmaceutical adverts. For those interested, it was the WordPress “Pharma Hack“, and it proved […]

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 […]
