A new projector allows floating 3D objects – from a model of the heart to a talking human head – to be viewed from any angle.
The RayModeler prototype, developed by Sony, is on display for the first time in the UK at an exhibit at the British Library, London, called Growing Knowledge. The device creates 3D images that viewers can see from all angles without stereoscopic glasses. Sensors that recognise gestures allow it to be spun around when you wave your hand in the desired direction.
The system can recreate both static and moving objects. A static object can be captured on a turntable with a single camera, whereas many cameras are needed to capture motion. The shots are transformed into 360 images to be displayed by an LED light source in the system.
The library is featuring the display because it could be a powerful tool for researchers. "It has clear applications in anatomy and physiology," says Aleks Krotoski, researcher-in-residence at the British Library. "If you have an MRI scan you could look at it closely in 3D and manipulate it."
