Gulval Four Evangelists

The Gulval Evangelists

I have just posted over on my blog some news about a discovery that I helped to make outside Gulval Church near Penzance in Cornwall. Using 3D recording techniques, and through careful analysis and filtering of the data, we now know what is depicted on all four sides of a large granite cross-base by the […]

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 […]

Building Rome in a Day

The billions of photos taken in cities across the world and uploaded to places like Flickr, Photobucket et al might suddenly have a very interesting use. The University of Washington are experimenting with the creation of 3D “point clouds” similar to those created by terrestrial laser scanners, from downloaded images. By sourcing images and applying […]

Lasers and Light

Lasers and Light from Wessex Archaeology on Vimeo. This is an animation that I put together at Wessex Archaeology for the Society of Antiquaries‘ Making History exhibition at Salisbury and South Wiltshire Museum. I posted some more information about the animation over at the Wessex Archaeology Computing Blog, so I won’t repeat myself here!

Google Sketchup: Free 3D modelling tool

I’ve been using Sketchup for a while now (demo version), initially seeing it at the MacExpo in London last year. It’s a brilliant tool, taking (in my opinion) a whole new approach to 3D modelling. It couldn’t be easier to use. Sketchup introduced a tool to export models straight into Google Earth, and the rest […]
