Directional hotspot

I know we have directional sound but is it possible to apply this to a hotspot image?
Example: I have a hotspot image in a pano that I want to alpha fade to 0.1 as the user pans towards it and fades back in as the user moves away from it.
It would also be nice if it faded back in after about 5 seconds on an 'onidle' action.

If anyone can point me in the direction of an example or of a basic source code for this I'll be very grateful.

Thanks.

something like this? this was a test i did last year the panos appear and dispear as you approach the windows to display the view.

http://www.virtualnorthland.com/panos/wells/1.html

<events onviewchange="show_hotspots_in_range()" />

<action name="show_hotspots_in_range">
set(i,0);
loop_hotspots(0);
</action>

<action name="loop_hotspots">
test_hotspot_in_range(get(hotspot[%1].name));
inc(i);
if (i LT hotspot.count, loop_hotspots( get(i) ) );
</action>

<action name="test_hotspot_in_range">
sub(hdistance, view.hlookat, hotspot[%1].ath);
mod(hdistance,hdistance,360);
if(hdistance GT 180, sub(hdistance,hdistance,360));
if(hdistance LT -180, add(hdistance,hdistance,360));
sub(vdistance, view.vlookat, hotspot[%1].atv);
mod(vdistance,vdistance,360);
if(vdistance GT 180, sub(vdistance,vdistance,360));
if(vdistance LT -180, add(vdistance,vdistance,360));
if(hdistance LT 0, mul(hdistance,hdistance,-1));
if(vdistance LT 0, mul(vdistance,vdistance,-1));
if(hdistance GT 40, set(hdistance,40) );
if(vdistance GT 40, set(vdistance,40) );
div(hdistance,hdistance,40);
div(vdistance,vdistance,40);
add(distance2,hdistance,vdistance);
sub(hotspot[%1].alpha,1.0,distance2);
if(hotspot[%1].alpha LT 0.0, set(hotspot[%1].alpha,0.0) );
</action>

Thanks VN, that's exactly what I'm looking for *thumbup*
Except in reverse.... I need the hotspot to dissapear when looking at it.
I've tried reversing the alpha values in the action but it's obviously a little more complex than that.

Thanks Michel, that works a treat.

Here's what it was for: http://www.projectsolutions.es/demos/hyundai/i30/tour.html
Spin round 180º and the head restraint fades.
Also, there are 3 example hotspots for more info on certain areas. They all work fine on my desktop but on the iphone only one will perfom it's function and it will only work once until the pano is reloaded.
Any idea why that would happen?

Yep.... I've only been a member of the forum for a few weeks and I'm accumulating quite a 'beer dept' already!
All I can say is, Si alguna vez estás aquí en España... mi nevera es su nevera! *thumbup*

Gracias
