Abstract: In recent years, the 3D display technology is not only a kind of show of technology, but also is integrated use implementation of relevant various technologies. 3D display technology itself has a lot of kinds of implementation way, which including 3D volumetric scanning, holographic imaging and integrated imaging; these 3D display technologies have their own characteristics. Combining with 3D display the related key technologies and development trend, this article analyzed the integration development prospects and the content of specific development of 3D display and the related technology.

Abstract: In view of LED in the lighting project, it cannot display the problem of 3D effect in lighting market at present. Taking single chip microcomputer as control core, this paper uses the two following chips as 74HC138 and 74HC595 to control the ranks of some three-dimensional lattice respectively. Then it controls 512 LEDs on and off, arbitrary depth and level of light in LED cube in order to show us stereoscopic effects.

Abstract: Belonging to the Bentley Microstation series which work as one of the BIM platforms, the Bentley Power Rail Track shows huge advantages in the railway design for its visibility, high efficiency, advance, reliability and so on. This paper introduces the way to build the digital terrain model, alignments, cross sections, turnouts and to display the three-dimensional model of the railway for the Bentley Power Rail Track 3D railway design software. It provides application preparation for the BIM railway design and achieves the preliminary exploration of BIM applications. Bentley Power Rail Track proves capable of the BIM railway design.

Abstract: Supply Chain Management (SCM) is an advanced management mode. But, the application in computers, circuit and automation control is still relatively little. This paper uses the principle of forward difference and Internet SCM control model to design Internet circuit control SCM-PC control system. This system prepares matlab control algorithm using SCM Management thought through the conversion principle of computer SCM signal. This system converts analog signal into digital signal using RCV420 current-voltage converter. It identifies digital signal using A / D converter of PC which achieves Internet automatic control of circuit. 3D result display of the information flow provides a technical reference for the application of computer in circuit and signal control.

Abstract: With the information technology development, the manufacturing informatization has developed rapidly in recent years. 3D computer aided design (CAD) has become indispensable for developing new products. Network also plays an important role in exchanging information. In this case, people have a growing tendency to exchange information by 3D model rather than text or images. Through network platform to provide 3D dynamic display and lectotype service becomes the trend of the development gradually. So in this paper, a 3D dynamic display and interactive lectotype system was presents for mechanical design. This paper put forward a solution to exchange information by 3D model by integration of 3D CAD and Web3D techniques. Use the Viewpoint technique to displays interactive 3D models. Base on SolidWorks to exchange the 3D CAD model to Viewpoint model, and generation 2D and 3D commonly format files for downloading. Use database management system to manage all kinds of data. Proved by practice, this system can significantly increase conversion and improve the customer experience

Abstract: Visual fatigue caused by 3D display was studied in a subjective experiment. Electroencephalographic, event-related potentials and some eye-associated parameters were recorded to measure fatigue. Results show that, the increase of blink duration, power of α wave, and latency of P300, together with the decrease of pupil size, can well reflect 3D visual fatigue.

Abstract: While 3DTV technology achieved great development in recent years, 3DTV program production can’t be wildly employed because 3D production is more complex than traditional 2D production. Stereoscopic camera parameters need to be well controlled, because the perceived depth range of stereoscopic display is limited by human factors and stereoscopic image should be kept within this limitation, so that the viewer can experience 3D video without any uncomfortable feeling. Recent stereoscopic image acquisition methods provide precise control to map depth range from scene to screen, but they don’t suit some shooting cases. In this paper, we present two new stereoscopic image creation methods, which are more practical than traditional ones. Additionally, our production methods are presented in two cases: (1) camera separation is unfixed; (2) camera separation is fixed. In the end, experiments are presented and the results show our methods can control the perceived depth very well.

Abstract: In this paper, the liquid crystal grating-based 3D display will be introduced, and emphasis on the ‘movable’ characteristic of the LC grating. To make LC grating tunable, the required lighted LC grating pixels would be controlled via programming in order to solve the following questions: the pixels loss or the single viewing point.

Abstract: This paper describes an eye naked 3D display cube, which can track a viewer’s position and render the stereo perspective scene in each display surface. The viewers can look the details of 3D models and scenes from any viewpoints. It seems as the real 3D objects lay in the display cube. It supports multi-viewer interactive in one scene. The viewers also can see the position of each other in own screen. They can co-operate in the same scene, although their field of view is independent of each other. The technologies of 3D perspective rendering, marker tracking and image processing are used for the 3D display cube.

Abstract: 3D displays become more and more prevalent. Most 3D displays are so complicated and expensive that they are unavailable for ordinary people. Moreover, none of them are interactive. In this paper, we introduce a novel interactive low cost 3D display based on polarized light phenomenon. The system includes a touch box and two mutually perpendicular LCDs with a piece of half-silvered glass which bisects them. This novel system permits: (1) superior quality of display and (2) a novel interactive experience. The principle of the linearly polarized light reflection and refraction is deduced by Fresnel equations. The touch box is used to simulate 3D mouse, which consists of two touch panels. To show how it works, we implemented a 3D game application and a set of interactions are introduced.
