02Mar2015 Mobile settings for Pano2vr version 3.x & 4.1 only

[etegration]

what will cause sluggish viewing? does this cube size setting matter? on iOS4 to 5 on a iPhone 4 (not 4S), the same pano was very responsive compared to a iOS6, 6.01 and now 6.1 on a iPhone5. Any feedback?

Maybe this?

Quick reply: The technique used in the panorama viewer is.... load panorama then the image is stored in the devices RAM memory area.

IF autorotate is on and set to 1.0° [1 degree] is considered a very fast rotation as the angle of view is stepping to the right 1°per screen refresh cycle.

autorotation set to ON at a much slower or smaller value 0.02° or 1/5th of 1 degree step to right.

Remember that a negative -0.02 will cause the image to rotate left. A positive value 0.02 will rotate to the right.

device displays initial view and then

rotates again 1/5th of 1 degree step to right
screen refreshes with new angle of view

then:

rotates 1/5th of 1 degree step to right
screen refreshes with new angle of view

And so on around the panorama image

The devices video screen refresh rate ? Faster screen refresh cycle means the screen will redraw the image faster.

The larger physical dimension size will create a larger tile Kb size of the panorama tiles means that much more data has to be processed by the video card.

Another thought... the devices WEB Browser ability to display the panorama.

I think all these variables can contribute to your devices behavior.

AND then your observations might be judgmental. The behavior we observe we might consider normal.

Would you consider letting us view your panorama ? URL please

It may be image compression.
Image compression is no longer done in iOS6, it was in iOS5 and earlier.
Example:
In the Mobile tab you would have set up an iPhone to use max screen size of 960px, cube face size 700px and image quality 80.
With iOS5 internal compression it was more like having image quality 65 to 70.
This just means you need to set image quality to 65 - 70 in Pano2VR.

Hopki

Hi
A question regarding high resolution panoramas.
I normally create a panorama in HD size (1920x1080px)

Would you suggest adding this into the mobile html5 device settings or better creating a new panorama.
My idea if user views the panorama on his desktop with an available resolution of 1920px it should be shown with that resolution.
Is this Possible or too tricky to use that high resolution with i-devices + android's. ?

I'm actually looking for the best multi panorama setting as most of us here are.

I use actually Hopki and 360Texas settings

--- /mobile tab
HTML5 AWARE flavor and use HTML5 using Flashfall back option for one of the above flash .swf's
Safari browser

Create Output Format for:
iPad 1 and 2 screen 1024 and tile 1024
iPhone 4 and 4s screen 960 and tile 700
iPhone 1,2,3 screen 480 and tile 416

settings cube: 1500
I would add: Mobile screen 1920 and cube face 1024
any comment appreciated if this doesn't create problems on any tablet device.

FYI, you might find php mobile detect source project/source code useful. It uses header information to determine if the browser is on a mobile device. Your post seem to be duplicating some of the testing needed to do this:
http://code.google.com/p/php-mobile-detect/

Of course the real problem is that there is no way to know how much a download is costing the visitor, or how fast their connection speed is (possible, but costly to send test packets, measure, ...) Without both it seems to me most sites are better off providing the user control over the size of the pano downloaded with a user interface element instead of using device type, screen width, etc. as surrogates.

Hello Rich,
Thank you for your post.

So when we create a tour, is there a generally well performing setting that is good for most mobiles no matter the type or os? Is there a tutorial on youtube? I am confused about the settings and understanding "cube face" total size, tiles and so forth. Am I the only one???

I suggest that for "normal users" a summary of this thread, 70 post long and lasting almost 2 years, is transformed by the administrators into a suggested standard workflow/settings info, becoming a tutorial or a guide. It would be a "best-practice" procedure for building a Flash+HTML5 standard panos and should be regularly updated, giving the limitations eventually identified for some devices.

I am trying to find a great way select different skins for different devices/screen resolutions.
There are script that help to detect the device used and his screen resolution and this scripts or codes can be added to the created html file.
While playing around with this subject it hit me:

Why using addition code to add the function "device/screen resolution detection" to be able to select different skins when the function is already there!

Pano2VR detects the users screen resolution and in the tag mobile we can set different image sets for set screen sizes.
I think here is the place to add the selection for skins like this:

mobiletab.jpg (93.64 KiB) Viewed 14613 times

This way you can create skins according to your selected Screen sizes - and because Pano2VR already selects the right set of images for the user device it than would be able to load a skin you define for the screen resolution.
I tried to find out how Pano2VR checks for the device properties, but the only different I could find between the output folders for a project with and without mobile screen sizes defined it the output.xml file:

without different screen sizes:

Code: Select all

<input tile0url="images/2nd Bedroom_o_0.jpg" prev5url="images/2nd Bedroom_o_preview_5.jpg" prev4url="images/2nd Bedroom_o_preview_4.jpg" prev3url="images/2nd Bedroom_o_preview_3.jpg" prev2url="images/2nd Bedroom_o_preview_2.jpg" prev1url="images/2nd Bedroom_o_preview_1.jpg" prev0url="images/2nd Bedroom_o_preview_0.jpg" tile5url="images/2nd Bedroom_o_5.jpg" tilesize="1581" tile4url="images/2nd Bedroom_o_4.jpg" tile3url="images/2nd Bedroom_o_3.jpg" tilescale="1.006325110689437" tile2url="images/2nd Bedroom_o_2.jpg" tile1url="images/2nd Bedroom_o_1.jpg"/>

with different screen sizes:

Code: Select all

 <input tile0url="images/2nd Bedroom_o_0.jpg" prev5url="images/2nd Bedroom_o_preview_5.jpg" prev4url="images/2nd Bedroom_o_preview_4.jpg" prev3url="images/2nd Bedroom_o_preview_3.jpg" prev2url="images/2nd Bedroom_o_preview_2.jpg" prev1url="images/2nd Bedroom_o_preview_1.jpg" prev0url="images/2nd Bedroom_o_preview_0.jpg" tile5url="images/2nd Bedroom_o_5.jpg" tilesize="1581" tile4url="images/2nd Bedroom_o_4.jpg" tile3url="images/2nd Bedroom_o_3.jpg" tilescale="1.006325110689437" tile2url="images/2nd Bedroom_o_2.jpg" tile1url="images/2nd Bedroom_o_1.jpg"/>
  <altinput tile0url="images/2nd Bedroom_o_800_0.jpg" screensize="1000" tile5url="images/2nd Bedroom_o_800_5.jpg" tilesize="800" tile4url="images/2nd Bedroom_o_800_4.jpg" tile3url="images/2nd Bedroom_o_800_3.jpg" tilescale="1.006325110689437" tile2url="images/2nd Bedroom_o_800_2.jpg" tile1url="images/2nd Bedroom_o_800_1.jpg"/>
  <altinput tile0url="images/2nd Bedroom_o_600_0.jpg" screensize="700" tile5url="images/2nd Bedroom_o_600_5.jpg" tilesize="600" tile4url="images/2nd Bedroom_o_600_4.jpg" tile3url="images/2nd Bedroom_o_600_3.jpg" tilescale="1.006325110689437" tile2url="images/2nd Bedroom_o_600_2.jpg" tile1url="images/2nd Bedroom_o_600_1.jpg"/>

In the xml file is stored the path and name of the different images sets and there is screensize="x". Is screensize="x" really all that is needed to detect the user screen resolution?
If so would be a code like this in the xml file selecting the skin:

Code: Select all

<input skinurl="/skinname_800.ggsk" screensize="1000" />

I forgot if you don't want to select a specific skin for specific screen resolutions the skin selector drop down could be set to default means using the skin form the settings tab.

[Sicadera]

Hi there.

I have pano2vr 4.1 and the skin related choices are missing.



What version do you have?

[Arnie]

Hello Sicadera
There is no skin selection, this is an idea I had to make it easy to use different skins for different screen sizes.

[Sicadera]

And instead you said pano2vr could be like this...
you said is like this...


It reminds me a radio show i heard when I was young...
