You can have more detailed information on Polarized 3D in Wikipedia. By restricting the light that reaches each eye, each eye sees a polarized image. Each filter passes only that similarly polarized light and blocks the other light. There are two types of polarized glasses: linearly polarized glasses and circularly polarized glasses, and this is how it works: two images are projected onto the glasses which contain two polarizing filters. Polarized 3D: this 3D system uses polarization glasses to create an illusion of a 3D image.
You may find more detailed information of Active shutter 3D in Wikipedia. It uses a pair of liquid crystal shutter glasses to watch, and can be applied to present 3D images on various types of displays, namely, LCD, Plasma TV, CRT, projectors, etc. You may get more detailed information of Anaglyph 3D in Wikipedia.Īctive shutter 3D: it is a technique of displaying stereoscopic 3D images, which works by presenting the image to the one eye which blocking the other eye and repeating that interruptions rapidly. As a result, what you get is a seriously distorted and quality degraded 2D video.ģD video system is divided into 3 different types: anaglyph 3D, active shutter 3D, and polarized 3D.Īnaglyph 3D: it is the earliest approach to present theatrical 3D, and this 3D media needs a pair of red and greenish-blue (cyan) glasses to watch.
Another point is that the simple and quick cropping sometimes cuts the frames inaccurately. After cropped, the square frames need to stretch to fill up the screen which is at the aspect ratio of 16:9 or 4:3. However, the cropped frames turn out to be square by simply cutting a half of the original 3D frames. The basic way to divide 3D frames is to crop the images, which is also employed by VLC to convert 3D videos to 2D. In the process of a 3D video conversion, the biggest challenge is to separate the frames shot from 2 perspectives without any distortion. In this way, a regular motion picture camera system is employed to record the images as seen from two perspectives and a special projection or eyewear is used to limit the visibility of each image to the watcher's left or right eye exclusively. The most common way to produce a 3D video originates from stereoscopic photography. How much, if any, should be converted to 3D models? When do you convert it? Which data do you convert? How can you avoid errors? What has proven successful for other companies?įill out the form below to access a white paper which outlines migration strategies that squarely address these questions and also covers objectives, return on investment considerations, quality issues, and best practices.In simple words, 3D video stands for three-dimensional video which offers a stereoscopic image by enhancing the illusion of depth perception to add a third dimension.
Switching from AutoCAD to SOLIDWORKS 3D CAD software will dramatically improve your business performance, but the investment often raises questions about how to handle legacy data. Here is a demonstration from the SolidWorks YouTube channel which will show you how a 2D DWG was converted on a SOLIDWORKS 3D model using the 2D to 3D tools built into SOLIDWORKS software. If there are any problems inherent in the AutoCAD drawing or caused by the translation, the SOLIDWORKS sketch repair tool will automatically fix these problems. If the drawing contains multiple orthographic views, you can arrange the 2D geometry onto a glass box layout making it easy to convert the 2D sketches into a 3D model. SOLIDWORKS includes an Import Wizard to allow DWG/DXF files to be imported directly into the sketcher – from there it can easily be turned into a 3D model. Design sketches and assembly layouts may represent the first step of a consumer product or a machine design and if they exist in AutoCAD, SOLIDWORKS can use them as the foundation for 3D geometry creation.
