Initial View and Auto-Spin Settings?

I'm on the verge of making the purchase, I think. I just need to know about a few things first:

1. How do I set the initial view of a panorama?

2. Can I (and how do I) turn auto-spin on and off?  Is it possible to control the speed of the spin?

Thanks.

Okay, I got the spin stuff down.  That's perfect.  But I'm still a little clueless on setting the initial view.  Here is the code as I have it now (below).  What do I change if I'd like the initial view to be exactly the opposite (left to right) of what it is now?

(APPLET archive = "ptviewer.jar" code="ptviewer.class" width=360 height=240)

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.

Love the product.  Off to purchase now.

Thanks. I can see that already. It's the 3-image hemispheres that sold me.  I took some 4 triples today, and they all came out perfectly. And that was just by eyeballing the position by sloppily aligning the lense over the tri-pod legs.  With the doubles, I usually shoot 20+ hemispheres per room, in hopes of getting one usable one.

Is it safe to assume that the head promoted on this site locks in to 3 equally-spaced locations?

100% Correct

Go to Kaidan and buy the correct pan head and detent rings for your camera.

QuickPan III CS - (Camera Specific)

Although 3 position detent rings are not listed on the web site (the last time I looked)  they are available.

"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.

Dave,

I'm sure you're right, as I have no idea what I'm talking about. All I can go by is what I learned during a little bit of fidget time.

But, with that said, when I adjust the FOV, it doesn't change the direction of the starting point.  It  changes the zoom level.  PAN seems to be the only one that adjusts the starting direction.

ERASE ERASE ERASE  you are correct.  FOV is zoom.  Right application wrong param name.  I have replaced FOV with Panmin/max and pan.

Too early in the morning today...  Thank you for quickly bringing that to my attention .

No problem.  I'm just happy to know I'm not going crazy afterall.  Or, at least this isn't an indicator of it.

Scott,

I'm not sure this is what your are after but here goes.

It's woth a metion for those who are newbies to PTViewer.

(PARAM name=auto value="0.0") is your auto spin

Set it to 0.2

and if you wish to auto spin the other way

add a "-" symbol like this

(PARAM name=auto value="-0.2")

Regards, Smooth
