Research scientists at universities are under increasing pressure from funding councils and charities to provide evidence of both the impact of their research and their level of public engagement. Fortunately, internet based services and social media provide a perfect platform for such activities if used correctly. YouTube has become the premier vehicle for distribution of videos and animations of research findings. This vast repository has also become an essential learning platform for everyone with internet access.
A less well known resource is Sketchfab, a repository of 3D models that can be viewed on any device, and in Virtual Reality (VR) with embedded animations. The 3D objects (assets) can be viewed, downloaded or purchased for animation building, as game assets or 3D printing. The access rights are determined by the model owner – not Sketchfab. Several major museums and universities are now using Sketchfab to display their ‘exhibits’.
Glasgow Life Sciences
Glasgow Life Sciences (GLS) is a new public engagement and BioAnimation service within the School of Life Sciences at the University of Glasgow. The purpose of the service is to collect and curate the best of the College of Medical and Veterinary & Life Sciences’ (CMVLS) 3D datasets and process them for inclusion in the GLS Sketchfab collection, which can be viewed here:
At the time of writing (early Oct 2019) GLS has collected contributions from 13 different researchers within CMVLS and we hope to collect many more. The ability to view models in VR using either a mobile device or fully immersive headset creates a unique learning opportunity for students grappling with the complex 3D nature of many biological structures. The structure-function relationship in most (if not all) biological structures can be difficult to teach effectively and therefore learn.
Technology and Art
Datasets are collected from users in their native/raw format (typically as a series of TIFF images). GLS post processing techniques involve thresholding, segmentation, mesh reduction and refinement, animation, texturing and lighting. The best of the collection will feature in a fully immersive VR art gallery that is nearing completion and will be released in late 2019. The Sketchfab collection and VR Gallery will be demonstrated at Pharmacology 2019 (the annual winter meeting of the British Pharmacological Society) which will be held in Edinburgh this year (15-17th December).
To view any of the GLS models in 3D simply browse to the address ( https://sketchfab.com/GLS ). To view in VR you will need a Google cardboard viewer and smartphone as a minimum device. Click on the ‘view in VR’ icon found in the bottom right corner of the model (3rd icon from the right). If your PC or laptop is connected to a fully immersive headset the model should work automatically. We have found Firefox to be a more stable browser for VR viewing. One of the most recent additions is a beautiful reconstruction of the Islet of Langerhans comprising several pancreatic beta cells containing insulin granules. The cell nuclei are also shown. The model was provided pre-constructed by Fiona McCulloch (Medical Visualisation Masters student) and Prof. Gwyn Gould.
Previously, 3D models such as the one shown above and the sheep embryo from the collection would have been used once in an animation and never reused. The GLS collection provides a permanent public place for these models and our plan is to use these in both undergraduate and postgraduate teaching. We also hope that other universities may use the datasets in their own teaching.
Some of the models have already been used in the construction of 3D animations for teaching. These can be viewed at the author’s website and YouTube channel (links below):

Author Biography
Craig DalyMSc
PhD SFHEAis a Senior Lecturer in the School of Life Sciences, University of Glasgow (UofG), and has been involved in cardiovascular research, at UofG, for over 35years. Recently Craig's role has become more teaching focused, leading to a Senior Fellowship of the Higher Education Academy. For 25 years Craig studied adrenergic pharmacology using confocal microscopes, fluorescent ligands and 3D image analysis to investigate receptor distribution in the vascular wall. More recently, Craig has been using and repurposing his archive of 3D confocal datasets to create animations and virtual reality environments for teaching physiology and pharmacology.
