[Solved] Showing the FOV & TILT on a panorama:

Boubou · May 17, 2011 at 9:43 AM

Goog morning everybody,

What kind of code I have to insert in my xml to get a little window showing the FOV (degrees) inside a panorama?

Thanks a lot for your help

Code

<plugin name="options"
	url="plugins/options.swf"
	/>

Thanks Jaydee, but I don't need the full options, just the FOV visible nearby my buttons

Code

<events onviewchange="showfovtext();" />
   <textstyle name="FOVTEXT" origin="bottom" edge="top" yoffset="190" textalign="center" background="false" border="false" fontsize="20" textcolor="0xFFFFFF" bold="false" effect="glow(0xFFFFFF,0.7,4,2);glow(0x000000,1,4,2);dropshadow(3,45,0x000000,2,0.6);" showtime="2.0" fadetime="1.0" />
   <action name="showfovtext">
  	copy(fov,view.hfov);
  	roundval(fov,2);
	  txtadd(msg,'HFOV=',get(fov),'°');
	  showtext(get(msg),FOVTEXT);
   </action>

Thanks a lot to those how helped me on Panophoto

And what should be the code for the tilt?
I saw something about that reading a post about compass, but I dont want a plugin, just text!

"<action name="showfovtext">
copy(fov,view.hfov);
roundval(fov,2);
txtadd(msg,'HFOV=',get(fov),'°');
showtext(get(msg),FOVTEXT);
</action>"

does that work have you tested it? i dont think hfov is valid. this is what the view tag supports i dont see hfov.

the below action should work but it is not tested.

"<action name="showfov_tilt">
copy(fov,view.fov);
copy(tilt,view.vlookat);
roundval(fov,2);
roundval(tilt,2);
txtadd(msg,'FOV=',get(fov),'°+ TILT='get(tilt),'°');

showtext(get(msg),FOVTEXT);

</action>"

Yes, it works fine!
Now, when I zoom to 90°, I have a HFOV of 90° on my screen (default or full screen) and the radar shows also 90°!!!
Thanks for the tilt, I will try it and tell you if it works

Like discussed on Panophoto.org, hfov and hlookat are the two main attributes used in radar algorythm (see the code)
to manage horizontal size and orientation.

For fun I have modified the code to manage a vertical radar...
It is running...
But it should combine the two rotations : horizontal and veritcal to draw the more realistic "radar".

Just a little change and now it's works perfectly

Code

<action name="showfov_tilt">
copy(fov,view.hfov);
copy(tilt,view.vlookat);
roundval(fov,2);
roundval(tilt,2);
txtadd(msg,'HFOV=',get(fov),'°+ TILT=',get(tilt),'°');
showtext(get(msg),FOVTEXT);
</action>
