Generating 360 degree stereoscopic images I've been playing around with generating 360 degree stereoscopic images for use with my Google Cardboard (other VR devices should work too). Basically what I do is generate two spherical image that are offset by 6cm, one for the left eye and one for the right. This are works pretty well, but I've noticed a problem. The problem is that when viewed in the forward direction the 3d effect is perfect, but if you turn around to look behind then it is broken. This makes sense, because looking forward the left image is offset to the left and the right to the right, but looking behind things are reversed so left is offset to the right and vise-versa. My question is, is there anyway to generate images that don't have this problem? Doing some searching I found this article. It says, "We rotate the cameras about their common pivot point..." in regards to the left and right image. I believe that's the problem I'm having. Currently when the spherical image is rendered it's rotating around the virtual visitor's center point, but with the scene viewed from a single eye in the center of the visitor. What I believe needs to happen is that the spherical view is rendered from a virtual eye on the left or right of the person yet still rotating around the center of the person. If my supposition is correct, then the question is, is it possible to change the renderer to do this? Anyone have any experience or thoughts on this? Thanks. |

Re: Generating 360 degree stereoscopic images I use Spherical Photo-rendering 8192x4096 and use name that end with _360 example minephoto_360.jpg and finely i ad the metadata on the jpeg file info as shown in picture in the link https://www.mediafire.com/convkey/b8d1/7wxw4ee96sjnh6n6g.jpg it work on mine cardboard and oculusVR it displays correct on Facebook as-well ---------------------------------------- To Draw or not to Draw ......

Re: Generating 360 degree stereoscopic images Do you generate two images, one for each eye, or just a single image? I agree it works fine as a 360 panorama, but when trying to combine two images is where I have problems. |

Re: Generating 360 degree stereoscopic images a single image .u find your self in the center of the image and can look in any direction ---------------------------------------- To Draw or not to Draw ...... Thats nolonger a question .. We draw |

Re: Generating 360 degree stereoscopic images Thanks for the example. I think I wasn't clear. I'm able to create 360 panoramas fine, and view them. The problem is that I want to create stereoscopic 360 panorama. Those are made from two images, one for the left eye and one for the right. Having this gives depth to the image so you can tell what's further away and what's closer. Here's an example I make, but it has the problem that I described in my first post. When you look towards the window it's fine, but if you look at the corner of the bed platform it's off a bit, and it's even worse if you look at the hanging chair. To generate these images correctly the SH3D renderer would need to render spherical images slightly differently than it does now. |

Re: Generating 360 degree stereoscopic images I have googled stereoscopic views but is not so easy . i think moving the virtual visitor 6cm to the left or the right is the best way in SH3d to generate 2 pictures ,but you already tried that so i cant help you maybe the results of search can help you further ; Sterioscopic 360panoramas youtube vids https://www.youtube.com/watch?v=AgW5stbchz8 Urls https://code.blender.org/2015/03/1451/ https://www.360cities.net/help/stereo_panos https://www.reddit.com/r/GearVR/comments/6fy12u/digitizing_stereoscopic_photos/ http://sideloadvr.com/detail.php?id=53 https://forums.geforce.com/default/topic/3568...-photo-creating-software/ prorgams Gimp ---------------------------------------- To Draw or not to Draw ......

Re: Generating 360 degree stereoscopic images So, I managed to hack together a fix. I added two new camera types to Sunflow, the raytracer used to generate the images. They are "Spherical Left" and "Spherical Right". They're very similar to the default spherical camera, but as they render the image the adjust the eye position accordingly. The code change for this was actually quite simple, it just took me a while to find the right place to make the change. Still, not bad for a few hours work. Here is an example using these new cameras. This seems to fix the problem and now gives good depth perception in all directions. Next I need to:

Re: Generating 360 degree stereoscopic images wow you done quiet a job there Am looking forward to your work and hope you fix it ,am not in java programing it all , if i look at the code it looks like it came from outerspace ..lol i use samsungVR to view mine mono360 pictures, stereo pictures bi displayed as images up/down _TB, Images left/right _TBS and displayed as 3dv i was satisfied with the mono360 i used, made about 400 of them but now you came up with stereoscopic Pictures ..lol now i want to experience the deference between mono and stereo The technic of stereoscopic_photos predates VR, previous century i do believe For start I am new at this Stereoscopic thingy ,but i have done some experiments white Stereoscopic imaging , i edited the Pictures left one of them untouched, the second one i cutout a pice from the left side and pasted to the right side of the Picture and finally i placed the edited picture on top of the untouched, one now we have a stereoscopic one .. but its a experiment i miss the extra depth Again i added some downloads for you 1 a movie from the mono360 picture as i experience it in Oculus headset and 2 the ST pictures i made with a bonus a original i found on the net http://www.mediafire.com/file/lmbn6i6lmcko77g/Video_for_Becky_360_8AM.rar http://www.mediafire.com/file/23m2o3yub1ut4ij/Becky_8AM_STPano_Test_360.rar ---------------------------------------- To Draw or not to Draw ......
