“…11 In one of the most researched methods, the voxels are formed on a rotating lightscattering screen, known as a diffuser, that sweeps an image projected onto it 360°. The projected image is synchronized with the rotation, so viewers watching the image see generated images of an object or scene that appear coherent from anywhere around it, 12 as outlined in figure 3a. In addition to mechanical methods, a 3D image may be produced electrically by a change in the polarization or transmittance of any of several light-scattering screens.…”

“…Our image generation methods take into account the display characteristics in terms of both geometry and resolution of the reproduced light fields. In particular, we extend a multiplecenter-of-projection technique [12,2] with a depth compression factor. We use the common sort-first parallel rendering approach, but rely on an adaptive out-of-core GPU renderer rather than fully replicating data across render nodes.…”

We report on a light-field display based virtual environment enabling multiple naked-eye users to perceive detailed multi-gigavoxel volumetric models as floating in space, responsive to their actions, and delivering different information in different areas of the workspace. Our contributions include a set of specialized interactive illustrative techniques able to provide different contextual information in different areas of the display, as well as an out-of-core CUDA based raycasting engine with a number of improvements over current GPU volume raycasters. The possibilities of the system are demonstrated by the multi-user interactive exploration of 64GVoxels datasets on a 35MPixel light field display driven by a cluster of PCs.

“…Its imaging quality is about the same as that of the Transpost. In recent years, the interactive feature has also been added [11,12,13]. In short, although the existing holography methods still need much improvement, the futuristic holographic display is very helpful for gastroscopy diagnosis as it can give a 3D structured information.…”

Abstract. Gastroscopy is a common procedure for diagnosing the diseases in upper GI tract, in which a large number of localized and sometimes unstructured images on different parts of the upper GI tract are captured. While it is effective, the procedure also requires experienced doctors to carefully exam these images in real time. As a result, errors may occur causing miss and/or false diagnosis. This paper presents a holographic displaying system that can display the images in a 3D structured manner. It consists of four steps. First, the gastroscopy images are acquired from the standard gastroscopy procedure. Second, a 3D image is generated by means of panoramic mapping. Third, the 3D image is transferred into four images. Finally, the images are displayed in a 4-side pseudo 3D holographic system. The new system is capable of showing 3D structured view, based on which the doctor can carry on diagnosis more effectively. With further development, it is expected that the new system will find practical applications in hospital soon.
