[Mobile Chrome] Green border around distorted video hotspot

Quoted from "360gradenfotografie" Thanks! The green line is gone, but unfortunately there's still a misalignment Fixed it! The video is now 480 × 640px and there's no green line or misalignment (MP4 and WebM). Before, the video was 718 × 888px. I read somewhere that the dimensions of an MPEG movie should be divisible by 8. Does anyone have something meaningful to say about this?

Flying arrow pointing towards hotspot

Quoted from "light_line" Hi, can you share the final code with us? Sure! I added this JS function to the page krpano is embedded on: Source code 1 2 3 4 5 6 7 8 9 10 function bearing(hlookat,vlookat,ath,atv) { const phi_1 = vlookat * ( Math.PI / 180 ); const phi_2 = atv * ( Math.PI / 180 ); const delta_lambda = (ath - hlookat) * ( Math.PI / 180 ); const x = Math.cos(phi_1) * Math.sin(phi_2) - Math.sin(phi_1) * Math.cos(phi_2) * Math.cos(delta_lambda); const y = Math.sin(delta_lambda) * Math.cos...

[Mobile Chrome] Green border around distorted video hotspot

Quoted from "spacerywirtualne" Take the test with the webm. You can use: https://krpano.com/plugins/videoplayer/#preferredformat Thanks! The green line is gone, but unfortunately there's still a misalignment: This only happens on Chrome for Android. The alignment on other browsers (Chrome, Firefox and Safari on a Mac, Safari on iOS and the Oculus Browser on an Oculus Go) I tested with is pixel perfect. Quoted from "spacerywirtualne" Oh, and important thing - renderer="css3d" or renderer="webgl"...

[Mobile Chrome] Green border around distorted video hotspot

Has anyone seen a green border like this? It only appears on Chrome for Android (v78.0, Android 10, Pixel 3). I also tested on Chrome, Firefox and Safari on a Mac, Safari on iOS and the Oculus Browser on an Oculus Go.

Flying arrow pointing towards hotspot

I found a approach: There's a excellent tutorial on how to calculate bearing and distance from one point to another on the globe. Using longitues and latitudes. I'll take those scripts as inspiration https://www.movable-type.co.uk/scripts/latlong.html

Flying arrow pointing towards hotspot

I'm creating an arrow (hotspot[arrow]) that points to a hotspot (hotspot[cross]). Right now, using the code below, it looks like this: The arrow should always be pointing to the center of the cross, but it doesn't. I guess I'm over complicating things in my code. So, do you have any suggestions how to approach this? Thanks!

Tweening layer scale is shaky

Quoted from "spacerywirtualne" Maybe use changeorigin That would reduce the shakyness, but it also changes the direction of the animation. Quoted from "spacerywirtualne" bdw, Declare the value for cycle earlier in the layer code. I did so on line 5 Quoted from "klaus.krpano" To disable that pixel-grid-fitting add accuracy="1" to the layer: https://krpano.com/docu/xml/#layer.accuracy That seems to solve it! Thanks https://virtuele-tours.nl/tour/tween/

Tweening layer scale is shaky

Quoted from "indexofrefraction" i think it has to do with a rounding issue when the layer is centered .... depending on the size there is a 1px shift where the layer is positioned ... you could try to have it right/left aligned for a test. i think it doesnt happen there Maybe... But how to fix it? Check https://virtuele-tours.nl/tour/tween/. It now cycles between align = center, left, topleft, top.

Tweening layer scale is shaky

Quoted from "Tuur" can you show some bare bone code or example? I just tried a bit but seems quite smooth to me. Sure! Source code 1 2 3 4 5 6 7 8 9 <layer name="test" align="center" height="100%" width="prop" url="bg.png" onclick="resize()" /> <action name="resize" scope="local"> if(caller.height == 100%, tween(caller.height,90%,2,linear); , tween(caller.height,100%,2,linear); ); </action> This is how the tweening works out: https://virtuele-tours.nl/tour/tween/ On my computer it's shaky/chopp...

Tweening layer scale is shaky

Hi, When I'm tweening a layer's scale (or with/height) and the layer is not aligned to one of the corners (align != lefftop, righttop, leftbottom, rightbottom), the animation is shaky. Like krpano has difficulty calculating the size and position of the layer for every frame. Any idea how this can be fixed? Niek

Shooting Stereoscopic 360s

PTGui also provides some basic information: https://www.ptgui.com/support.html#6_39 If you'd like to create a depthmap from a stereo 360, you could use stereo2depth for example. But the results are messy. The krpano examples are created with the Kandao Obsidian I guess: https://www.kandaovr.com/obsidian-go/. Their (Windows only) software offers depthmap export.

3D transitions

Quoted from "klaus.krpano" In this example KEEPMOVING is used as flag for the scene loading to allow moments during blending. And for the 3D transition both, the image.ox/oy/oz and view.tx/ty/tz settings are initially set to an offset, and then during blending only the view.tx/ty/tz values are tweened back to 0 Awesome! I'll dive into it immediately.

krpano 1.20

Quoted from "klaus.krpano" The Cardboard device database stores only the DPI for a device and the physical size will get calculated by the screen pixel-size the browser provides and that DPI value. Now the problem - when the device reports a wrong screen-size, that calculation fails of course. In the webvr plugin from the previous krpano version I was also using an own device-database where the physical size directly was stored and not just a scale factor, so a different screen sizes from the b...

3D transitions

Hi Klaus, Thanks for your reply! The transition you're proposing (example2.html) looks like this, schematically: Source code 1 2 ----------[blend]--------- ----------[zoom]---------- | ----------[zoom]---------- To smoothen the transition, a scheme like this would be better: Source code 1 2 ----------[blend]---------- ----------[zoom]---------- | ----------[zoom]---------- At the moment it doesn't seem possible because only the current image's ox/oy/oz can be modified. Right? Is there a workarou...

3D transitions

Quoted from "a.pu" Actually the best thing to be done using tx, ty transitions is presented here http://panosphera.ru/gallery/transitions/ Thanks, I know that example! It looks really nice, but when loading panos as hotpots I can't use scenes, multires, stereo images, etc. A great solution would be to tween ox/oy/oz of the current and other <image> tags on the fly.

3D transitions

I was hoping that with the new release it would be possible to create "3D transitions" easily. Of course it's possible to create depthmaps and position every scene in 3D space (using ox, oy and oz of the <image> tag), and then use view.ty/tx/tz to fly between them. This obviously gives the best results, but it involves a lot of manual work for every tour. I would like to do the following:[click] on hotspotMove the current pano image in 3D space so that the viewer approaches the hotspot (1 sec)De...

Oculus GO & KRpano

Quoted from "jeromebg" Hi guys, Just saw (late) that 3Dvista are providing a online service to download tours on the Oculus Go and be able to watch them offline. Their UI is clear and clean. https://youtu.be/Kxo9o3e2uwE Are they using a offline proxy or something to achieve that ? Would love to be able to do the same with krpano tours of course ;) I guess they've created a progressive web app: blog.heroku.com/how-to-make-progressive-web-app
