Thanks, Klaus. Clearly, I need to study the documentation on how to access WebXR APIs. Is it allowed to code any of these directly in JavaScript? Regards, Tom
Is krpano able to access OpenXR APIs, especially for controller devices? I would like to make virtual tours that play easily on Quest 2 etc.
Two improvements to the vtour editor gui would be welcome. 1) ability to rotate as well as position hotspots 2) ability to re-order the thumbnails, changing the next/previous sequence
In the tools gui, the make vtour droplet can accept image files added one-by-one. the gui shows them as a numbered list, however it always sorts the list by name. It would be convenient if instead it kept them in order of addition.
I just made a multiresolution tour with krpano tools 1.20.9 using vtour-multires.config. In tour.xml I include vtourskin_design_ultra_light.xml. In other words, everything is stock krpano latest release. Using krpano testing server, everything looks fine on PC bowsers, including 'fake VR' mode in response to VR button. This is true both on the machine hosting testing server and other PC or Mac on the same LAN; but when I load the tour in a phone or Oculus Go via the LAN there are no zoom, pan, o...
Ah, I understand the distinction. The pano is OK but the depth map/3D model has discontinuities. I am just now studying how it may be possible to improve depth maps by forcing their edges into alignment with edges detected in the images. I hope to show some results soon.
That is definitely a stitch error. We should try to make or find some CGI panos with depth maps, those will be geometrically perfect though artificially simple. I am working with Andrew Hazelden on depth mapping some photographic stereo panos, using available tools that make almost-acceptable maps. Will upload when I have them.
Klaus, I have also been in touch with Andrew Hazelden, who is ready to help by rendering CG views with depth maps. He says he can easily make both omnistereo panoramas and simulated fish-eye photos with depth maps. I have sent you his email, and also asked him to join this forum.
...And of course the depth map must be calibrated so it can be related to the view geometry. The most useful depth maps give distance, in absolute units such as reciprocal meters. Stereo depth maps are often scaled relative to the separation of the pupils, but this is not feasible when there are more than two views.
Thank you Adam. This is a big help. As Klaus says, the geometry of the viewpoints is also required, to render shifted views properly. In an omnistereo pano like this, the viewpoints lie on a horizontal circle around panocenter, Both the dirameter of the circle, and the angular separation of the viewpoints must be known. For example, in a typical photographic rig of mine, the circle has a diameter of about 80mm and the moving eye points are about 165 degrees apart; that is, the lens pupils are sl...
Hi Klaus I'm sorry to say I do not now have any stereo panoramas with separate depth maps. But I am working very hard on software to create them. The main target is large multi-camera "bubble" arrays, but should work also with normal two-camera capture. In the mean time, the Blender guys should have no trouble making synthetic test panos of this type, I will ask Andrew Hazelden and der Mische. In my experience the sense of presence is much stronger in VR when the image is stereoscopic. But there...
Is it, or could it be, possible to generate stereo views from two images, each with its own depth map, in such a way that each view gets pixels from both images, according to what is visible from the current viewpoint? This is a simple case of compositing using a z-buffer. It would largely alleviate the problem of "missing pixels" that results from rendering stereo pairs for a single image + depth map. This process could be extended to more than two source images and made more efficient by tilin...
Zitat von »klaus.krpano« Quoted from "Klaus" what are layered depth maps? A layered depth map represents the appearance of a 3d space from a range of viewpoints, rather than just one; but a limited range, for example a sphere 1m in diameter. It is a specialized 3d model good for rendering high resolution stereoscopic views with parallax shift and occlusion, as might be seen by a stationary observer turning the head and tilting the body. Perfect for VR stills and video frames. In the context of ...
Hi Klaus, It is fantastic that you have made krpano render 3D models. Any plans for panos with layered depth maps? Best regards, Thomas
Of course WebVR had to be replaced, but doing it this way is a disaster for our entire industry. Millions of krpano pages -- and lots of others -- can suddenly no longer be viewed immersively on the most popular VR headsets. I get the impression that the VR publishers -- 360Cities, RoundMe, Kuula, etc -- were not expecting this. Klaus, can you say how big a job it will be to revise all those pages? Everybody, please scream as loud as possible for Oculus to restore WebVR until the industry has ac...
Thank you a million times, Klaus. Once again you have moved VR technology into the future in a completely practical way. I look forward to using these new tools to build real 3D experiences.
Technically more correct but not working is a disaster for Go users who love 360 VR. Please do everything you can to normalize the situation. BTW no such problem manifests on my GearVR/Samsung S6 despite its running what is nominally the same browser. Also note that Roundme.com does not have this problem.
Hello Klaus I'm wondering if you have any firm ideas or plans about playing 6-degrees-of-freedom images ("head bubbles", whether still images or video frames)? I have no doubt that you have been thinking about that, we all have. Sooner or later a lot of VR images will be of this kind, and I think sooner. It is definitely time to establish some working standards for distributing and rendering 6-dof images, and I would hope that you will play a leading role. Please contact me by e-mail if you pref...
Sorry, Klaus, I was wrong. Edge displays webVR material just fine, krpano panos better in fact than any other browser I have used. No trace of shimmer, and quite crisp, I think due to foveated rendering. My problem was that I am running WMR on a laptop, which like all laptops has Intel Integrated Graphics, and also a strong nVidia GPU. Microsoft apps, including Edge, use the IIG by default. Switching Edge to the GPU with nVidia Control Panel brought webVR to life.
With a new Samsung Odyssey Windows Mixed Reality headset, one of the first things I tried was visiting 360Cities on the Edge browser; and I got a big disappointment. Same on Roundme.com and the krpano webVR demo page: no immersive image, just a black rectangle. After selecting webVR mode one goes through these steps: MS portal asks permission to enable webVR; krpano displays hmd setup screen; MS portal asks permission to "go fullscreen"; then black screen. Double clicking the black screen brings...
