Hi all. I have made a single shot fisheye panorama that can be viewed at http://www.avica.com.au/08_panoramas/beautysalon/beauty.htm . The trouble is I feel it is too pixelated and "up close". I am trying to find out how the initial view parameters can be changed to zoom it out about 10%. The closest parameter setting I have found is <PARAM NAME="initialView" value="0.0, 180.0, 1.0"> where the last field is supposed to affect the zoom angle?? Not sure if I'm on the right track though as when I alter the setting it makes no difference to the movie. Any help much appreciated.

Hi Lance.

Try this (replace your code between the applet tags with this):

<APPLET archive = "ptviewer.jar" code="ptviewer.class" width=360 height=240>
          <PARAM NAME=pwidth value="1400">
          <PARAM NAME=pheight value="700">
          <PARAM NAME=roi0 value="i'beautysalon.jpg' x350 y0">
          <PARAM name=wait value="wait.gif">
          <PARAM name=frame value="bar.gif">
    <param name=tilt value="-10">

<PARAM name=fov value="100">
          <param name=barcolor value="0000ff">
          <PARAM name=bgcolor value="ffffff">
          <PARAM name=auto value="0.5">
          <PARAM name=panmin value="-90">
          <PARAM name=panmax value="90">
          <param name=shotspot0   value=" x292 y225 a395 b240 u'ptviewer:startAutoPan(0.5,0,1)' ">
                  <param name=shotspot1   value=" x309 y225 a412 b240 u'ptviewer:stopAutoPan()' ">
                  <param name=shotspot2   value=" x326 y225 a429 b240 u'ptviewer:startAutoPan(0,0,0.97)' ">
                  <param name=shotspot3   value=" x343 y225 a450 b240 u'ptviewer:startAutoPan(0,0,1.03)' ">
        </APPLET>

 

I added a "fov" line. You can also specify fovmin= and fovmax= parameters to limit the zoom depth in and out. By the way, you don't necessarily have to call out <PARAM name=x...> for every control setting. Have a look at our Gallery page code at RotoPix.com (right-click and select "view source".) All of your parameters can be called out at once. Might save you some time and simplify your code. Hope this helps. Welcome to the forum! Nice fisheye shot by the way.

Thanks so much for all your help Brian. Your site looks great. Love the fisheye lens. Took your advice and looked over your code. I didn't realise you could cut it down that much. I have just relied on the generated code and make some minor adjustments as it's all a bit beyond me. The fov works great and I have uploaded the new script. Now I'm going to go through them all and work out some min and max values. Thanks again and good luck to you.

Cheers
Lance

Thanks, Lance. Glad I could be of service to you.

Much of what I've learned has been gathered bit by bit from generous people sharing their knowledge and experience, as you're seeing now. Collectively the VR industry improves and evolves as a whole. I'm grateful for these forums... You'll be amazed what can be learned here if you stick around and pay attention.

See you around (there's a VR pun in there somewhere),

Brian

Hopefully one of you can help.

When I picture a 360 degree pano I see the wait picture and the bar uploading.

I made some panos < 360 degrees and used the roi0 param. Now I get some kind of frame to see. My wait picture just for a moment and the bar not loading at all.

How can I change this?
