Getting to the Point: A 3D Digitisation Template for the Human Os Coxae

<p dir="ltr">Deposited are outputs generated by a project running between 2023-2024 and funded by the Engineering and Physical Sciences Research Council. This was undertaken by the project's first author while an EPSRC-funded Research Associate at the School of Mathematics and Statistics under the supervision of Prof. Paul Blackwell. These particular materials support a paper published in the Journal of Computer Applications in Archaeology titled "Getting to the Point: Defining, Reconstructing and Investigating Shape Through a Procrustean Protocol" (DOI: https://doi.org/10.5334/jcaa.161).</p><p dir="ltr">Contained within the deposit is a 3D template of the human os coxae. The template defines the shape of the os coxae through a suite of landmarks and semi-landmarks; a document describing the location of landmarks and the anchor points for curves along which semi-landmarks are positioned is also provided. The 3D template was created in Viewbox 4 (version 4.1.0.12, dHAL Software) and can be employed to digitise scans of the human os coxae in freely-available versions of that platform. Viewbox 4 is downloadable at https://www.dhal.com/viewbox.htm, where tutorials on how to open, customise and employ templates can also be found. Regarding customisation and further application, a document is provided detailing procedures/code which can be employed in R (an open-access statistical environment) to determine the optimal number of landmarks/semi-landmarks required to capture shape in a structure as well as how missing data can be reconstructed through either 'geometric' or non-parametric 'statistical' methods. See attached LICENSE text file.</p><p dir="ltr">Data generated through application of the template stored here are amenable to geometric morphometric analysis, specifically coordinate-based methods such as Procrustean techniques. Testing has shown that the template is capable of capturing complex and subtle morphological patterns in a computationally efficient manner.</p>
