Joanna Ostapkowicz studying the cohoba stand.
The cohoba stand was taken off display, especially to be 3D laser scanned and studied. It took two and a half days to record the whole sculpture using a non-contact laser scanning system. High resolution photographs were taken of areas of particular interest identified by Joanna Ostapkowicz during her research.
Close up of the carving on the underneath of the nose of the cohoba stand figure - one of the many areas of interest identified on the cohoba stand.
The cohoba stand has some areas that are very hard to reach using a laser scanner. In areas such as around the hips and under the arms the data had to be collected from multiple angles.
The cohoba stand from the back showing the spine, arms and hips – the areas inside the arms were difficult to scan.
Once back in Liverpool, using the 3D data collected in New York, a computer model of the cohoba stand to sub-millimeter resolution was created. The high resolution photographs taken of important parts of the cohoba stand were mapped onto the 3D model.

The video clip below shows the 3D model with a texture (colour map) applied.
A 3D interactive viewer has also been created of the MMA cohoba stand.
