Nice!
Get on board friends, I think the Blend4Web train is leaving the station!

Golly, you are a Blender Master! Thanks so much for taking the time to show me this. Give me a couple of days to work on it. I need to shoot some video out in the field to show how the spherical camera app works.

I am working on a spherical photo viewer for a wetland construction project that requires a lot of photo documentation to show progress.

As you can see, I have some wrinkling at the bottom center of the photo sphere.
This photo was acquired with the free Google Camera app. This is what it looks like:

Now that everybody with a smart phone can easily produce high quality spherical images, I think it might work out very well to make spherical photo viewers for websites. If we can streamline a process to UV map these images to a good mesh, I will make a video to show anybody how to do it. What I have done so far is working pretty good I think, except for the wrinkled texture at the bottom.
Here is the .blend:

Blend4Web has the advantage of swinging the camera around and it gives more 3d depth effect. My skybox is shaped more flat to give the effect that you are standing on the ground.

I was also thinking of adding extra area to the image to make it square and use this for labels or signs maybe.

I noticed in the Sports Car Demo ( https://www.blend4web.com/en/demo/sportscar/ ), you have a pretty smooth spherical image. Do you think I could achieve that with these spherical images from the Google Camera?

Wow, very nice!

Okay, great! I am making progress. Is there a setting to do an html export with transparent sky so the background color will actually be the background of the file with the iframe?

Is there an easy way to make an iframe with no border and no settings menu to make a seamless website integration?
*SOLVED*

Let me know if I got anything wrong. I can still make changes.
(Hey, where should I post my videos on this forum?)

Thanks for the links. I am starting to learn a few things. I may pester you with a few questions but once I understand a concept, I will do a video for it. I think there will be people who learn Blender specifically because of Blend4Web. There are many web development technologies that are becoming obsolete. Web developers who have never authored 3D content will be looking to keep up with the times. So I think videos that show each step assuming no knowledge of Blender would be cool.

Mikhail,
I would love to see a walk-through of how to add a redirect link with the new node editing, add a sound and add an animation. I think those three things would be a great start for anybody starting out with Blend4Web.
If you need English voice-over, let me know.
I just finished a Blend4web install video: https://www.youtube.com/watch?v=vxvZOAsfKpY
I have a Blend4Web SDK tour video in processing, I will post a link when it is done.

Okay, good. Thanks for the reply.
