Embodiment Construction

[0073]

[0074] One of the Specific Embodiments As shown in FIG. 1 , the external structure 10 of a true three-dimensional display is composed of an upper cover 12 , a rotating screen 11 , a glass shell 14 , a gas 15 filled in the sealed glass shell, and a lower cover 13 . A motor is installed in the casing of the upper cover 12; the rotating screen 11 is connected to the motor to be driven and rotated; the glass shell 14 forms a closed space around the rotating screen 11 together with the upper cover 12 and the lower cover 13; the closed space is filled Gas 15 with lighter components, such as hydrogen or helium, may be evacuated to form a space with little air resistance so that the rotating screen 11 can rotate at a high speed; projector equipment is placed in the casing of the lower cover 13 to project The image light source sent by the machine is projected onto the rotating screen 11 through the reflector. The detailed internal structure of one of specific embodiment is s...

Abstract

The invention provides a true three-dimensional displayer which produces and displays a body three-dimensional graphic image or a true three-dimensional graphic image. A quick rotating projection screen is obtained by projecting continuous two-dimensional images to produce a body three-dimensional image. A principle is that the two-dimensional images are integrated and a body three-dimensional space is filled by utilizing vision persistence of a human vision system so as to form true three-dimensional vision. The true three-dimensional displayer is characterized by adopting a double-face rotating screen, a V-type double-face reflecting mirror technology, a cross rotating screen, a P-type pyramid four-face reflecting mirror technology, a displayer sealing glass casing, a light gas filling technology, a multipath beam-combining projection system, a bit layer setting technology, a blend true three-dimensional displayer technology integrating semitransparent reflection and mirror spectra vision imaging and the like.

Description

technical field [0001] The present invention generally relates to the field of three-dimensional (3D) displays. More specifically, the present invention relates to a system and method for real 3D (Real 3D or True 3D) display based on a multi-projector rotating screen, where True 3D is also called volumetric 3D. Applications suitable for true 3D displays include: particle system calculation and display in graphics processing, finite element calculation and display, physical simulation and display of aerodynamics and fluid mechanics, meteorological analysis, earth system simulation and display, space simulation and display, Tomographic image processing (CT or MR) and display in medical imaging, molecular dynamics simulation and display, air traffic control and display, etc. Background technique [0002] At present, there are three main three-dimensional (3D) display technologies: Stereo 3D, Volumetric 3D, and Holographic 3D. [0003] Holographic display technology can compl...
