North High Cross, Clonmcnoise (Turntable Movie)
Only the shaft and part of the base of this cross survive.There is a tenon or projection on the top of the shaft which would have fitted into a mortice in the underside of the missing cross head.
The shaft is made from limestone and is ornamented on three sides only
with animal, human and abstract designs divided into panels. The front or west face has four and a half panels all containing interlace designs. On the south side above the lowest panel of interlace is a human figure in a Buddha-like pose while the top panel shows a lion with a projecting tongue.
The upper hull of the north side has a tall panel with two animals placed one above the other and a damaged human figure at the top with spiral ornament on the body. This last figure has been compared with figures in the Book of Kells. The ornament is similar to that on the cross at Bealin in Co. Westmeath and other fragments from Clonmacnoise and Banagher and this group has been dated to soon after 800 AD.
The base, which was only recently exposed by excavation. was originally a Millstone and is made of conglomerate sandstone. It is only the core of a composite box-like stone base which has not survived, but the grooves cut for the upright corner stones and the side panels can be seen. St. John’s Cross at Iona in Scotland has a composite base surviving intact.

Description
|
The Artec EVA scanner is used to generate high resolution models of surfaces with small scale detail. The Artec EVA uses structured light to record. A forensics tent is used to create a controlled lighting environment and ensure measurement can proceed regardless of the weather when used outdoors. Scanning is undertaken with the fastest speed setting (15 frames per second) and with a minimum 400 mm depth of field. The data is recorded with sufficient overlap between scans to ensure easy registration.
Resolution 0.5 mm
Accuracy 0.1 mm
Accuracy over distance 0.03% over 100 cm
Texture Resolution 1.3 mp
Colours 24 bpp
Light Source flash bulb (no laser)
Video frame rate 16 fps
Exposure time 0.0002 s
Post-processing is done in Artec Studio 9 software: individual scans are edited, aligned, before a final surface is generated using global registration, fusion, and a small objects filter algorithm. If required, a textured surface can also be created. The model is exported from Artec Studio 9 as an .obj file. For dissemination purposes a 3D pdf of the model is generated using Geomagic Studio 2012. |
