the scene are removed from only one eye.One way to create a three-dimensional effect is to use a raster system to alternately display two views at different refresh intervals. Through the glasses observation screen, each lens is designed to be a high-speed alternating shutter, which can synchronously block the display of another view, figure 2.20 gives a pair of stereo glasses, which is composed of a liquid crystal shutter and the

Principles of holographic photos Holographic photography is to use laser technology for photography, recording all the light information of an object on the negative film. Unlike normal photography, it only records a projection of an object. Therefore, when the weight of a negative film is present, it seems extremely lifelike In the viewer's eyes. The visual effects produced by the film are exactly the same as those when watching the object. The principle of holographic photography, simply put,

Many technologies are needed, such as semiconductors, optoelectronics, Micro motors and other support.It has been a huge wav

photosensitive area of the camera lens, the focal length parameter (and therefore the calculated FoV field of view), or the steel structure design and fabrication of the stent, there is no guarantee that the required parameters can be accurately achieved, and a few mm of optical or mechanical errors may seem innocuous, But for perfectly's cubic image, one or more obvious cracks will inevitably be left in the final immersive scene. What's more, there

, away from the lens, red eye condition appears less likely. 　　 ▲ Photo Source: Digiphoto Camera World Error 3 Destroy the picture atmosphere The flash can create shadows, making the subject look more stereoscopic, but sometimes it also becomes the culprit in destroying the atmosphere. In situations like stage performances, concerts, exhibitions and other occasions where you need to keep the lighti

is filled at the rear of an optical lens. When light and image pass through and are projected to the CCD surface from the lens, the CCD will generate current, convert the inductive content into digital data for storage. The larger the number of CCD pixels and the larger the size of a single pixel, the clearer the collected image. Therefore, although the number of CCD is not the only key to determining the

Discussion on the size and stereoscopy of the slice -- Some friends in the group are struggling to upgrade the fuselage FF or buy a new 24G There are a lot of arguments on the internet... after reading a bunch of ideas, make sure you vomit blood and don't say it. The more you see, the more you get confused.To put it simply, the key to the difference between stereoscopy lies in the depth of field... I think a lot of people will not be able to see a picture after reading it. There are basically th

Crop factor)Because the imaging chip in the camera is usually less than 35mm film, it has different characteristics when you place the lens for the SLR camera on the DSLR camera. It seems that the image has been cropped, so there is a cropping coefficient. For example, a 100mm lens will change to a 160mm lens on a camera with a cropping factor of X (for example,

SharpGL learning notes (3) Projection Transformation and viewpoint transformation, sharpgl learning notes Starting from this section, we use the VS2010 extension of SharpGL to directly generate the SharpGL project. If you do not see the following SharpGL project when creating a project, find a directory named "SharpGL 2.0 Visual Studio Extension" in the source code of SharpGL and install the directory named SharpGL. vsix vs2010 extension, and then restart your vs2010. Using the above SharpGL

. Enhancing the visual effect of depth of field Depth of field is very important for shooting. Every photographer does not want his or her photos to have no stereoscopic effect, and it looks like a plane. Therefore, we need to add some objects for display relativity to increase the depth of field during shooting. For example, to take a distant mountain, you can add a person or a tree to the foreground of the screen. With a wide-angle

a mirror in the end the form of H5 is now a very popular marketing play , usually in the H5 page by imitating the lens stretching, so that different elements of the picture is presented in the audience in a way of expression. In the H5 page does not cut, the picture does not cut the case, achieves the one go the browsing effect . For this cool H5 visual gameplay, in the content display and to attract the attention of users, can be said to have a very
