In the summer of 2012, Sustainable Archaeology worked with Art Gallery of Ontario (AGO) conservator Lisa Ellis and curator Sasha Suda to micro-CT scan 16th century prayer beads, in order to understand how these complex and intricately carved beads were constructed. Their work is the subject of recent AGO Art Matters blog, titled "Conservation Notes: A very fine resolution". The project was also featured in the Spring 2013 CODART e-zine. The video below (posted on the AGO's Youtube channel) shows a surface rendered model of one of the prayer beads.
This animation is a surface rendered model of the prayer bead, created from a 21 gigabyte, three-dimensional volume of micro-CT data, using VGStudio MAX. Animation created by Zoe Morris.
