OCTOBER 2018 56 CompositesWorld Advancing composites through virtual and augmented reality A review of technologies that are bridging the technical divide between the virtual world of design and simulation, and the real world of composites manufacturing and repair. » Virtual reality. It's a term many associate with the fictional worlds created in movies such as e Matrix and the playgrounds found in today's sophisticated computer games. Since the early days of CAD, engineering and manufacturing, composites engineers have used sophisticated software to create accurate virtual representations of advanced composites products and technologies. It could even be argued that virtual reality is simply an outgrowth of these virtual technologies that have long serviced the industry. But what makes virtual reality and associated technologies distinct is the interaction they provide between virtual and actual worlds. Developed to enable filmmakers and video game developers to capture the movements of live actors and insert them into animated film and video formats, virtual reality (VR) applications today can, for example, enable an engineer or tech- nician fitted with strategically placed body sensors to become immersed in a virtual manufacturing environment — perceiving and interacting with life- size, 3D models of prospective machines and systems, future components or assemblies, or become part of a virtual manufacturing floor and move about the environment as digital avatars. In these and other practical ways, compos- ites design and manufacturing engineers have reaped and are more widely reaping many benefits from VR technologies. From monitors to immersion CHIL moves 3D models from monitors to a virtual environ- ment, where engineers can perceive and interact with life-size 3D models.
