Wait a second, what does\u00a0stereoscopic even mean? Do you remember the\u00a0movie\u00a0AVATAR or\u00a0IMAX 3D theaters where you have to wear special glasses? These examples\u00a0are\u00a0filmed and designed to present stereoscopic images. These\u00a0glasses deliver separate images to\u00a0your left and right eyes in order to convey\u00a0depth information.\u00a03D rendered games and animations generally work with stereoscopic images. On the other hand, films, surprisingly, are rarely\u00a0filmed as\u00a0stereoscopic images.<\/p>\n<p>It is often staggering to\u00a0view flat spherical images in VR, because your visual fields are fully surrounded by images. But, in my opinion, added depth information through stereoscopic imagery will provide more realistic and immersive experiences. Adding depth in HMDs does not require additional things that users need to do. It is similar to\u00a0watching a color TV rather than a\u00a0black and white TV.<\/p>\n<figure id=\"attachment_1893\" aria-describedby=\"caption-attachment-1893\" style=\"width: 1773px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1893 size-full\" src=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam.png\" alt=\"stereo cam\" width=\"1773\" height=\"939\" srcset=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam.png 1773w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-300x159.png 300w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-768x407.png 768w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-1024x542.png 1024w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-700x371.png 700w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-1400x741.png 1400w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-232x123.png 232w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-464x246.png 464w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/stereo-cam-624x330.png 624w\" sizes=\"auto, (max-width: 1773px) 100vw, 1773px\" \/><\/a><figcaption id=\"caption-attachment-1893\" class=\"wp-caption-text\">Examples of stereoscopic spherical cameras<\/figcaption><\/figure>\n<p><span style=\"font-family: Calibri;font-size: 15pt;font-weight: bold;color: red\">I <\/span><span style=\"font-family: Calibri;font-size: 15pt;font-weight: bold\">Stereoscopic images in VR and HMD<\/span><\/p>\n<p>In fact, most VR HMDs, such as Oculus Rift, are born to provide stereoscopic images. It is fairly easy to introdeuce\u00a0stereoscopic scenes\u00a0for simulated 3D games and animations; however, filming stereoscopic images in the first place creates complex issues. We are still in the early phases of creating\u00a0production and distribution standards\u00a0for\u00a0stereoscopic spherical images on HMDs&#8217; VR software.\u00a0So, it is sad to say, there is no known legitimate and copy-right safe method to watch your AVATAR 3D from\u00a0one of its DVD or Blue-Ray discs, and there is\u00a0limited content readily available so far. A Hulu app for the\u00a0Oculus Home version started to provide such content, but available titles are still limited.\u00a0Meanwhile, you can search and download some of this footage from Oculus Home or homepages of 3D filming productions. There is\u00a0some footage at the\u00a0Temple DSC as well.<\/p>\n<p><a href=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1952\" src=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325.jpg\" alt=\"IMG_20160805_112325\" width=\"873\" height=\"655\" srcset=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325.jpg 4160w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-300x225.jpg 300w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-768x576.jpg 768w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-1024x768.jpg 1024w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-700x525.jpg 700w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-1400x1050.jpg 1400w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-232x174.jpg 232w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-464x348.jpg 464w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/08\/IMG_20160805_112325-624x468.jpg 624w\" sizes=\"auto, (max-width: 873px) 100vw, 873px\" \/><\/a>Or, you can\u00a0create your own videos\u00a0to experience how it feels. The above image shows examples of stereoscopic cameras, including the\u00a0<a href=\"https:\/\/code.facebook.com\/posts\/1755691291326688\/introducing-facebook-surround-360-an-open-high-quality-3d-360-video-capture-system\/\">Surround 360 camera<\/a>, <a href=\"http:\/\/www.panocam3d.com\/camera.html\">Panocam 3D<\/a>, and 360 HERO. They will allow you to take quality stereoscopic spherical videos, aka 360 3D or 3D 360 depending on their marketing names.\u00a0As you might have already guessed,\u00a0they are pricey, and they need specified software that fits their hardware.<\/p>\n<p><span style=\"font-family: Calibri;font-size: 15pt;font-weight: bold;color: red\">I <\/span><span style=\"font-family: Calibri;font-size: 15pt;font-weight: bold\">Can we use simple spherical cameras for an alternative solution?<\/span><\/p>\n<p>This summer,\u00a0I want to film a\u00a0stereoscopic spherical 3D video with\u00a0Temple DSC&#8217;s resources. DSC already has two <a href=\"https:\/\/theta360.com\/en\/about\/theta\/s.html\">Theta S cameras<\/a> for taking spherical video images. Theta S is a simple fish-eye 360 camera, so\u00a0I will see if a 3D printed rig\u00a0can turn these two cameras\u00a0into stereoscopic filming equipment. Although I imagine their resolution is not as crisp as other high-end devices, I hope\u00a0they will provide a decent image quality for\u00a0VR experiences. In fact, because of the current limits of video bandwidth, I expect this solution to cover the current standard resolutions. Though, it is unclear until we try and see the results. I also plan to design a\u00a0time-lapse slider on the rig.<\/p>\n<figure id=\"attachment_1916\" aria-describedby=\"caption-attachment-1916\" style=\"width: 939px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1916\" src=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336.jpg\" alt=\"IMG_20160728_103336\" width=\"939\" height=\"697\" srcset=\"https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336.jpg 4160w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-300x223.jpg 300w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-768x570.jpg 768w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-1024x760.jpg 1024w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-700x520.jpg 700w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-1400x1039.jpg 1400w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-232x172.jpg 232w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-464x344.jpg 464w, https:\/\/sites.temple.edu\/tudsc\/files\/2016\/07\/IMG_20160728_103336-624x463.jpg 624w\" sizes=\"auto, (max-width: 939px) 100vw, 939px\" \/><\/a><figcaption id=\"caption-attachment-1916\" class=\"wp-caption-text\">DSC&#8217;s brand new 360 spherical cameras<\/figcaption><\/figure>\n<p>In order to make the stereoscopic spherical camera, there are few things to consider. First, I need a stereoscopic camera rig to create the\u00a0proper distance between cameras and a ball head that I can put the rig on. Second, I need to figure out how to\u00a0edit and stitch stereoscopic spherical videos together in order to load it onto the Oculus Rift.
