The proliferation of various VR and AR applications in education in recent years brought about the popularisation of realistic, high-definition 3d models, In particular, the fields of medicine, biology, engineering and architecture experienced an increased use of such models due to their ability to provide a realistic visualisation of objects that may not be suitably portrayed with illustrations and static images. However, these models, and their application in various teaching and learning scenarios, are no longer limited to expensive VR/AR headsets and advanced programming skills. With the help of open-source technologies, it is now possible to render 3d models in the browser. This talk will introduce participants to a basic workflow using Three.js - an open source JavaScript library used to render 3d models on a webpage, or any of the most popular VLEs, offering learners the opportunity to interact with them on a wide range of devices. During the talk, participants will have access to several Codepens featuring working exemplars and be able to test and interact with the models as well as see the underlying code in real-time. The talk will be particularily useful to learning technologists, multimedia designers and instructional designers working in HE.
