Projection- Abstract. Light field 3D displays represent a major step forward in based light field 3D displays9–11 represent one of the visual realism, providing glasses-free spatial vision of real or virtual scenes. Applications that capture and process live imagery have to most practical and scalable approaches to glasses-free 3D process data captured by potentially tens to hundreds of cameras visualization, achieving, as of today, a 100 Mpixel total 3D and control tens to hundreds of projection engines making up the resolution and supporting continuous parallax effect. human perceivable 3D light field using a distributed processing Various applications where 3D spatial visualization has system. The associated massive data processing is difficult to scale beyond a specific number and resolution of images, limited by the added value have been proposed for 3D displays. Some capabilities of the individual computing nodes. The authors therefore of these applications involve displaying artificial/computer analyze the bottlenecks and data flow of the light field conversion generated content, such as CAD design, service and mainte- process and identify possibilities to introduce better scalability.
