      This DevalVR is a nice web integrated panorama, pretty good if you want a web delivery, no doubt about it. Halcyon is standalone fullscreen, have you tried the pano scenes? it runs at your highest monitor settings, with an 8k map. http://www.lightcraftresearch.com/Panoramas.zip
      I have been playing with creating a bunch of spheres that you can travel between, its kind of neat as there are all these bubbles of images you can move between.

      just on another note... i have created a nice demo of the solar system with nasa's high res maps.
      what are the copyright limitation with these maps?
      can i put out a demo with them? is credit to nasa all thats needed? or do i need special permission? im not sure if the planet maps are public domain.

        I tried Halycon. But I got a very low fps viewing the 3D scenes. I still have a 9800GT. So that may be the reason.
        The panoramas you provided worked perfectly smooth.
        To really put this to test I made a 10000x5000 panorama (50Mp - 45mb jpeg file)
        DevalVR has a standalone player of only 1.5mb - no install - freeware
        It runs full screen (just like the webversion btw)

        DevalVR could handle this perfectly smooth on fullscreen 1280x1024 - 9800GT - Core2Duo 6600

        When I feed this panorama to halcyon. I could handle this perfectly smooth too. However there were some issues in the sky. see pic. Don't know what this could be? I tried to reload the scene, but it didn' go away. You can have the panorama if you want to make tests on it.

        So IMHO there is no difference in smoothness. But there is in usability. When you try to zoom in halcyon the image gets completely warped. This doesn't happen in DevalVR + the image is a bit more sharper.

        [EDIT]
        Another thing I noticed is that halcyon displays the panoramas wrong. It's flipped horizontally. So e.g. in panorama2 when you look at the stairs, the kitchen should be to the left. As it is in the picture. But when I look at it with halcyon the kitchen it to the right. So you should really fix this.

          those vertical lines are from your image size, resize the image to a bit depth number and all should be good.
          for instance 8192 x 4096

          as for the flipping, i made a sphere, put a normal modifier on it, placed a camera inside applied the pano texture, and exported it.
          I noticed the mirrored panos later, and did a photoshop flip. but to fix this all i need is a spherical uvw modifer in the stack with -1 in x tiling.

          When i have a spare minute ill make a new pano file.



          Warning!...if you dont like code stop reading here.

          you can even fix this yourself, by opening the .mob file in notepad and changing these 2 lines...

          SetScale 1.000000 1.000000 1.000000 to this SetScale -1.000000 1.000000 1.000000

          and also

          SetCullBackface to SetNoCull


          what this does is flip the mesh in x, this makes the normals flipped back outwards, so we change it to 2 sided by the command SetNoCull

          if you really want to get your hands dirty with the code...
          try this.

          copy paste the geo node paragraph, change its position, change the image, alter the cameras digits to lengthen its clipping. and you have a whole lot of panorama planets. providing your card has enough memory to hold them all.

          which you could easily overcome come with LOD...but i better stop before people fall asleep

          cheers

            I believe that's fixed then. Didn't realize it was that easy.

            I think you have great potential in the engine. But I personally wouldn't use it for panoramas.

            [edit]
            I can't really follow you with the panorama planet thing
            But it seems you have some nice tricks up your sleeves. So keep us posted!

              I wasnt banking on a killer pano app, it was just one of those neat ideas you have at 2 in the morning lol

              try this mob file.

              http://www.lightcraftresearch.com/PanoSpheres.ASE.MOB

              a whole lot of these would look cool if they cover a large resort.

                Jep those ideas of 2 in the morning...

                Just tried the mob file and it's really fun. It could be used for creative purposes I think.
                At the moment I'm working on a schoolproject (yes I'm still a student) in which I'm using panoramas as the medium, trying to rethink the possibities of panoramas. This could be one of them :P
