Thanks, Klaus

Can one easily set up the new sphere<->cube droplet to create a given cube size?

The web browser in my LG 3DTV cannot convert an image in either sbs or over/under format to 3D.. With an interlaced 3D image it would not need to do anything, or even know the image is 3D.

I'm running into situations where, at seemingly random instances, we are getting an "FATAL ERROR: - invalid encryption!" for XML that is being encrypted on-the-fly leveraging the "-out=stdout" parameter with krpanotools -encrypt.
When I say random, I mean a user will run into this error on a particular scene, reload the tour, go back to the same exact scene, and all is good. If the error was present each time a user went to the scene, then there would be an issue with my XML generation.

Here is a link to a tour on our "preview" domain with the full-encryption code in-place where I can confirm users have run into this issue.

I personally have not run into this in my testing, but one user running into this is one too many.

When I say encrypting on-the-fly, I mean leveraging PHP to handle the encrypting of XML at time of request/load.

My sequence goes like this:

1. The xml is generated & loaded into the output-buffer
2. Krpanotools is registered ( ensuring it is registered ).
3. If registration is successful we proceed, else we output the buffer and exit, basically rendering unencrypted XML.
4. If we are successful with putting the output-buffer into a temporary xml file, we proceed, else we output the buffer and exit, basically rendering unencrypted XML.
5. If we are successful with encryption, the encrypted XML is rendered and we remove the temporary XML file.
6. The encrypted XML is loaded into the tour.

I'm assuming that when an encryption error happens, in my case, the unlink ( file delete ) does not occur. That is why I have several XML files in the directory the temporary XML files is placed.
I've run these files through XML validators ( multiple, to make sure that this is a valid test ) to check their integrity and they come out clean as a whistle.

I could put an encrypt-error handler in-place at step 5 ( above ) but I don't know what the exact output/return, if any, would be in the case of an error.

Here is the code-block that handles this:

ob_start();
include_once XP_LIBRARY . "xml/get_scene_xml.php";
$obContent = ob_get_contents();
ob_end_clean();


$reg_code   = "my_reg_code";
$output     = array();
$return_var = 0;
exec( KRTOOLS_PATH . ' register ' . $reg_code, $output, $return_var );


if ( !empty($output) && $output[1] == 'Code registered.' ) {


    $my_filename = "scene_xml_";


    if ( isset( $_COOKIE['sess_ref'] ) && !empty( $_COOKIE['sess_ref'] ) ) {
        $my_filename .= $_COOKIE['sess_ref'];
    } else {
        $my_filename .= $tour_ID;
    }
    $my_filename .= ".xml";


    if(file_put_contents( $my_filename, $obContent )){
        $my_file_path = KRENC_PATH;
        $my_file_path .= $my_filename;
        $theoutput    = system( KRTOOLS_PATH . ' encrypt -p -in=' . $my_file_path . ' -out=stdout' );


        if ( $theoutput ) {
            unlink( $my_filename );
        };
        
    } else {
        echo $obContent;
    };


} else {
    echo $obContent;
};


exit();

In the previous version I have used "convertdroplets.config" to change the output of Convert CUBE to SPHERE droplet.bat.

This doesn't work for the new .exe droplet. Is there a way to change the output format (e.g. jpg instead of tiff) of "Convert SPHERE CUBE Droplet.exe"?

Thanks a mil!

IMPORTANT!

Bug report

bingmaps radar html5 version working wrong, inverse rotating

Same bug in 13 14 krpano versions

Quote from klaus.krpano

For me it works correctly - here a quick test case - left Google Maps / right Bing Maps:
https://krpano.com/krpano.html?xm…google-maps.xml

Best regards,
Klaus

On my machine with firefox (on win 7-64bit), there is a bug of orientation within bing map(the radar is 180° rotated). It's work fine with chrome.

Quote from klaus.krpano

Do you have a link to your example?

Well, it's in examples from krpano package (googlemaps example)
just replace googlemaps to bingmaps and that's it, we will see wrong radar direction.

I have tested pr13, pr14, pr16 krpano versions with bingmaps html5 radars, all versions has same bug

Andrey

Sorry, you are right, it depends on browsers some of browsers has a bug with bingmaps rotation

In my case it's Safari - bug, Mozzila - ok, Chrome - bug

And here is test from your link

And the radar drawing code is very simple and independent of any browser or system stuff, so not sure what there could go wrong there...

Yep, that's what i thought too, and was really wander about this :))

It's on my Mac

But here is the test on Windows (Win10 64) system

More and more strange ! I try it again and now, on my machine, it's still buggy with firefox... and also buggy with Chrome ! So, I also tested IE and it's work fine.

If the issue is not easily replicable, perhaps it's a problem on the bing map server side ?? (and also perhaps involving connection location ?)

{how can I delete this unwanted quote?}

I'm sorry to hear this about the LG browser's video mode, but not surprised. How did you determine it?
That browser also crashes on panos with large cubeface sizes, so is really not much use.
But by using the TV as a 4k 3D monitor, we should still be able to show interlaced stereo from web pages.

Quote from klaus.krpano

I have also a LG 3DTV - it's a 4k TV with passive 3D - but the TV browser there doesn't render webpages in the native 4K resolution, the browser only uses a 1920x1080 resolution - and with that interlaced stereo output is not possible - interlaced stereo would require a 1:1 unscaled rendering at the screens physical resolution...
