"Never mind. Finally figured it out. In case anyone else is wondering:Changing (PARAM name=pan value="0") to (PARAM name=pan value="180") does a... well... a 180. "
Hmm lets rethink this for a moment.
Your image is a full full 360 degree sphere but when you look at it in your favorite photo editor it is a rectangle. Typically in ptviewer will first point to the center of the image. That is 50% from left to right and 50% from top to bottom.
This center location IS called Panmin/max and pan = 0 or zero.
PanMin and Max is what puts the eye of the camera on the horizon. Lets say that the PAN = 0
Now since 0 is mid center in the image the:
panmin is (-180 deg) -180 from center point 0 to the left image edge
panmax is (180 deg) 180 from center point 0 to the right image edge
It follows that the rotation will now be a full 360 degrees.
It also follows that when you first open your image the (viewer) camera eye will see middle center of the image because you have set the PAN to be 0 zero. If you have a special attraction that you want the visitor to see first that is 90 degrees right side from the center of the image then set the Pan = 90. Same thing for left make Pan = -90. If your initial interest point is somewhere in between.. trial and err test to find that PAN location.
A simple way for PhotoShop user to put your item of interest at PAN = 0 is to open your image in PS, then select FILTERS | OTHER | OFFSET and a dialog box will open allowing you to tick mark "WRAP" to automatically scroll the image off the right side back onto the left side.
Specify a number of 'offset' + or - pixels and the point of interest will rotate around to the middle of the image at or near PAN = 0 for you. Then in the applet param you can leave PAN = 0.
Other photo editors may also have this wrapping feature.
[hopefully while no one but SCOTT was reading this I edited above to replace words FOV for PAN] Thanks Scott.
