Earlier this year I was commissioned by Sustrust to digitally reconstruct the then-collapsed Carwynnen Quoit, a neolithic dolmen, using existing 3D laser scan data. This would be used to inform the physical reconstruction of the monument. I was also asked to investigate and report on a number of stones adjacent to the quoit which were thought to have been worked or decorated in antiquity.

The ‘rock art’ panels (a mixture of natural and hand-made lines, not necessarily as part of a single deliberate piece) were recorded in 3D using Structure from Motion (SfM) photogrammetry.

On summer solstice 2014, the capstone was lowered into place by crane in front of hundreds of spectators, marking an end to a four year project.

The graphical output that I produced was used on leaflets and publicity, as well as extracts from my report on the potential rock art. Below are some of those images, used with permission.
