Spacespex™ Anaglyph—The Only Way to Bring 3Dtv to the Masses
SPACESPEX™ ANAGLYPH—THE ONLY WAY TO BRING 3DTV TO THE MASSES By Michael Starks © M. Starks 2009 May be reproduced provided nothing is added, omitted or changed-- including this copyright notice. SpaceSpex™ is the name I applied to my versions of the orange/blue anaglyph technique in 1993. In fact the Gang Li/ColorCode and some models of SpaceSpex use amber or orange/brown rather than yellow, but they are on a continuum. Like all the bicolor anaglyph methods it is compatible with all video equipment and displays and I think it’s the best of the methods using inexpensive paper glasses with colored lenses. Until someone comes up with a way to put hundreds of millions of new 3D TV’s in homes which can use polarized glasses or LCD shutter glasses, anaglyph is going to be the only way for mass distribution of full color high quality 3D over cable, satellite, the web or on DVD. However the solution I have proposed for Set Top Boxes, PC’s, TV sets and DVD players for the last 20 years is to have user controls, so those with display hardware that permits polarized or shutter glasses or even autostereo viewing or who want 2D can make that choice from the single 3D video file. This is the method of the TDVision codec, Next3D, and of Peter Wimmer’s famous StereoScopic Player (a new version due end of 2009), (all of which should appear in hardware soon) and probably the best stereoplayer of all in Masuji Suto’s StereoMovie Maker, and is being incorporated in most well known software DVD and media players. -
The Uses of Animation 1
The Uses of Animation 1 1 The Uses of Animation ANIMATION Animation is the process of making the illusion of motion and change by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation. Animation can be recorded with either analogue media, a flip book, motion picture film, video tape,digital media, including formats with animated GIF, Flash animation and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced. Animation creation methods include the traditional animation creation method and those involving stop motion animation of two and three-dimensional objects, paper cutouts, puppets and clay figures. Images are displayed in a rapid succession, usually 24, 25, 30, or 60 frames per second. THE MOST COMMON USES OF ANIMATION Cartoons The most common use of animation, and perhaps the origin of it, is cartoons. Cartoons appear all the time on television and the cinema and can be used for entertainment, advertising, 2 Aspects of Animation: Steps to Learn Animated Cartoons presentations and many more applications that are only limited by the imagination of the designer. The most important factor about making cartoons on a computer is reusability and flexibility. The system that will actually do the animation needs to be such that all the actions that are going to be performed can be repeated easily, without much fuss from the side of the animator. -
Virtual Reality and Visual Perception by Jared Bendis
Virtual Reality and Visual Perception by Jared Bendis Introduction Goldstein (2002) defines perception as a “conscious sensory experience” (p. 6) and as scientists investigate how the human perceptual system works they also find themselves investigating how the human perceptual system doesn’t work and how that system can be fooled, exploited, and even circumvented. The pioneers in the ability to control the human perceptual system have been in the field of Virtual Realty. In Simulated and Virtual Realities – Elements of Perception, Carr (1995) defines Virtual Reality as “…the stimulation of human perceptual experience to create an impression of something which is not really there” (p. 5). Heilig (2001) refers to this form of “realism” as “experience” and in his 1955 article about “The Cinema of the Future” where he addresses the need to look carefully at perception and breaks down the precedence of perceptual attention as: Sight 70% Hearing 20% Smell 5% Touch 4% Taste 1% (p. 247) Not surprisingly sight is considered the most important of the senses as Leonardo da Vinci observed: “They eye deludes itself less than any of the other senses, because it sees by none other than the straight lines which compose a pyramid, the base of which is the object, and the lines conduct the object to the eye… But the ear is strongly subject to delusions about the location and distance of its objects because the images [of sound] do not reach it in straight lines, like those of the eye, but by tortuous and reflexive lines. … The sense of smells is even less able to locate the source of an odour. -

ChromoStereoscopic Rendering for Trichromatic Displays Le¨ıla Schemali1;2 Elmar Eisemann3 1Telecom ParisTech CNRS LTCI 2XtremViz 3Delft University of Technology Figure 1: ChromaDepth R glasses act like a prism that disperses incoming light and induces a differing depth perception for different light wavelengths. As most displays are limited to mixing three primaries (RGB), the depth effect can be significantly reduced, when using the usual mapping of depth to hue. Our red to white to blue mapping and shading cues achieve a significant improvement. Abstract The chromostereopsis phenomenom leads to a differing depth per- ception of different color hues, e.g., red is perceived slightly in front of blue. In chromostereoscopic rendering 2D images are produced that encode depth in color. While the natural chromostereopsis of our human visual system is rather low, it can be enhanced via ChromaDepth R glasses, which induce chromatic aberrations in one Figure 2: Chromostereopsis can be due to: (a) longitunal chro- eye by refracting light of different wavelengths differently, hereby matic aberration, focus of blue shifts forward with respect to red, offsetting the projected position slightly in one eye. Although, it or (b) transverse chromatic aberration, blue shifts further toward might seem natural to map depth linearly to hue, which was also the the nasal part of the retina than red. (c) Shift in position leads to a basis of previous solutions, we demonstrate that such a mapping re- depth impression. duces the stereoscopic effect when using standard trichromatic dis- plays or printing systems. We propose an algorithm, which enables an improved stereoscopic experience with reduced artifacts. -
A Novel Walk-Through 3D Display
A Novel Walk-through 3D Display Stephen DiVerdia, Ismo Rakkolainena & b, Tobias Höllerera, Alex Olwala & c a University of California at Santa Barbara, Santa Barbara, CA 93106, USA b FogScreen Inc., Tekniikantie 12, 02150 Espoo, Finland c Kungliga Tekniska Högskolan, 100 44 Stockholm, Sweden ABSTRACT We present a novel walk-through 3D display based on the patented FogScreen, an “immaterial” indoor 2D projection screen, which enables high-quality projected images in free space. We extend the basic 2D FogScreen setup in three ma- jor ways. First, we use head tracking to provide correct perspective rendering for a single user. Second, we add support for multiple types of stereoscopic imagery. Third, we present the front and back views of the graphics content on the two sides of the FogScreen, so that the viewer can cross the screen to see the content from the back. The result is a wall- sized, immaterial display that creates an engaging 3D visual. Keywords: Fog screen, display technology, walk-through, two-sided, 3D, stereoscopic, volumetric, tracking 1. INTRODUCTION Stereoscopic images have captivated a wide scientific, media and public interest for well over 100 years. The principle of stereoscopic images was invented by Wheatstone in 1838 [1]. The general public has been excited about 3D imagery since the 19th century – 3D movies and View-Master images in the 1950's, holograms in the 1960's, and 3D computer graphics and virtual reality today. Science fiction movies and books have also featured many 3D displays, including the popular Star Wars and Star Trek series. In addition to entertainment opportunities, 3D displays also have numerous ap- plications in scientific visualization, medical imaging, and telepresence. -

3D-Con2017program.Pdf
There are 500 Stories at 3D-Con: This is One of Them I would like to welcome you to 3D-Con, a combined convention for the ISU and NSA. This is my second convention that I have been chairman for and fourth Southern California one that I have attended. Incidentally the first convention I chaired was the first one that used the moniker 3D-Con as suggested by Eric Kurland. This event has been harder to plan due to the absence of two friends who were movers and shakers from the last convention, David Washburn and Ray Zone. Both passed before their time soon after the last convention. I thought about both often when planning for this convention. The old police procedural movie the Naked City starts with the quote “There are eight million stories in the naked city; this has been one of them.” The same can be said of our interest in 3D. Everyone usually has an interesting and per- sonal reason that they migrated into this unusual hobby. In Figure 1 My Dad and his sister on a keystone view 1932. a talk I did at the last convention I mentioned how I got inter- ested in 3D. I was visiting the Getty Museum in southern Cali- fornia where they had a sequential viewer with 3D Civil War stereoviews, which I found fascinating. My wife then bought me some cards and a Holmes viewer for my birthday. When my family learned that I had a stereo viewer they sent me the only surviving photographs from my fa- ther’s childhood which happened to be stereoviews tak- en in 1932 in Norwalk, Ohio by the Keystone View Com- pany. -
Towards Quantifying Depth and Size Perception in Virtual
Jannick P. Rolland Towards and Quantifying Depth William Gibson and Size Perception in Virtual Department of Computer Science, Environments CB3I75 University of North Carolina Chapel Hill, North Carolina 27599 Dan Ariely Department of Psychology, CB 3270 Abstract University of North Carolina Chapel Hill, North Carolina 27599 With the rapid advance of real-time computer graphics, head-mounted displays (HMDs) have become popular tools for 3D visualization. One of the most promising and chal- lenging future uses of HMDs, however, is in applications where virtual environments enhance rather than replace real environments. In such applications, a virtual ¡mage is superimposed on a real image. The unique problem raised by this superimposition is the difficulty that the human visual system may have in integrating information from these two environments. As a starting point to studying the problem of information integration in see-through environments, we investigate the quantification of depth and size perception of virtual objects relative to real objects in combined real and virtual environments. This starting point leads directly to the important issue of system calibra- tion, which must be completed before perceived depth and sizes are measured. Finally, preliminary experimental results on the perceived depth of spatially nonoverlapping real and virtual objects are presented. I Introduction Head-mounted displays (HMDs) have become popular tools for 3D visu- alization following the rapid advance of real-time computer graphics. They pro- vide 3D information to the user by presenting stereoscopic images to his eyes, similar to a simple slide stereoscope. The main difference is that the two images are scanned on two head-mounted miniature displays and can be updated in real time using fast computer graphics. -
