ZScreen
ZScreen is a push-pull electro-optical liquid crystal modulator that is placed immediately in front of the projector lens or computer screen to alternately polarize the light from each video frame. It circularly polarizes the frames clockwise for the right eye and counterclockwise for the left eye. The RealD 3D system now showing in theaters is using the ZScreen that was invented by Lenny Lipton.

RealD Cinema
RealD 3D is a digital stereoscopic projection technology made and sold by RealD. It is currently the most widely used technology for watching 3D films in theaters. Worldwide, RealD 3D is installed in more than 26,500 auditoriums by approximately 1,200 exhibitors in 72 countries as of June 2015. Technology RealD 3D cinema technology is a polarized 3D system that uses circularly polarized light to produce stereoscopic image projection. The advantage of circular polarization over linear polarization is that viewers are able to tilt their head and look about the theater naturally without seeing double or darkened images. However, as with other systems, any significant head tilt will result in incorrect parallax and prevent the brain from correctly fusing the stereoscopic images. The high-resolution, digital cinema grade video projector alternately projects right-eye frames and left-eye frames, switching between them 144 times per second. The projector is either a Texas Instruments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lenny Lipton
Leonard Lipton (May 18, 1940 – October 5, 2022) was an American author, filmmaker, lyricist and inventor. At age 19, Lipton wrote the poem that became the basis for the lyrics to the song "Puff, the Magic Dragon". He went on to write books on independent filmmaking and become a pioneer in the field of projected three-dimensional imagery. His technology is used to show 3D films on more than 30,000 theater screens worldwide. In 2021, he published ''The Cinema in Flux'', an 800-page illustrated book on the history of cinema technology. Early life Lipton was born in Brooklyn, New York. He majored in physics at Cornell University after starting out in electrical engineering. A self-described "mediocre student", he only excelled once he found a field he loved. Lipton urged schools to be more "accepting of eccentric people with a different point of view because we are the people who make the difference." Career Puff, the Magic Dragon Lipton was 19 when he wrote the poem that wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RealD
RealD Inc. is a private company known for its RealD 3D system, which is used for projecting films in stereoscopic 3D using circularly polarized light. The company was founded in 2003 by Michael V. Lewis and Joshua Greer. The company was taken public on the New York Stock Exchange (NYSE) in July 2010, trading under the ticker RLD. It re-privatized in 2016 by the private equity firm Rizvi Traverse Suhail R. Rizvi is an Indian-American businessman and co-founder and Chief Investment Officer of Rizvi Traverse Management LLC.

Between 2005 and 2007, the company purchased StereoGraphics Inc. and optical components technology company ColorLink, a provider of rear-projection television (RPTV) equipment, polarizing film and optical technologies. RealD developed its technology to create its 3D cinema systems. References External links * Companies list ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Imaging
In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction. Motivation and applications The research of 3D reconstruction has always been a difficult goal. By Using 3D reconstruction one can determine any object's 3D profile, as well as knowing the 3D coordinate of any point on the profile. The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design ( CAGD), computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. For instance, the lesion information of the patients can be presented in 3D on the computer, which offers a new and accurate approach in di ...
