Set "North" of a spherical image --> prealign

I want to set the north of a tour to the same direction in all images. I´m using "prealign" because I don´t have any gps or "north" data. I´m rotating the panorama in the tour and then I estimate the degrees to prealign. Then I test and set prealign again until its fine.
Is there another option to do this faster? For example that I can see the ath value of the correct view and use the difference of starting view als prealign value?

So I have to see the ath-value of the actual view. Is there a plugin?

Thank you,

Do you want to set north when loading each scene? You can display the hlookat readings in the console and calculate the difference amendment

<events onviewchanged="trace(view.hlookat);" />

i always use this code to get spherical coordinates of panorama under mouse pointer:

<action name="get_coordinates">
screentosphere(mouse.x, mouse.y, toh, tov);
roundval(toh, 2);
roundval(tov, 2);
txtadd(txt, 'ath=&quot;', get(toh), '&quot; atv=&quot;', get(tov), '&quot;');
trace('ath=', toh, ' atv=', tov);

<events name="coordinates" onmousedown="get_coordinates();" keep="true" />

also if you wanna mesure ath roughly without click and console:

<events name="lookat" onviewchange="copy(hl, view.hlookat); Math.round(hl); copy(layer[tech_info].html, hl); " keep="true" />
<layer name="tech_info" url="plugins/textfield.swf" align="lefttop" html="" keep="true" />

You'll find your coordinates under 'numbers'.…74910#post74910
