Hi,
a few weeks ago i was experimenting to put the drag3d at the right mouse button.
As there seems to be no pressed and pressedelement on the rightbutton i came to this.
I have some question though.
so..
This seems to work quite nice
<style name="drag3dright" onover.addevent="hithot = name;" onout.addevent="hithot= '';hit = false;" />
<events name="rightmousebutton" keep="true" ondown="Drag3DDown();" onup="Drag3DUp();" />
<action name="Drag3DDown" type="js" >
<![CDATA[
var hot = krpano.get("hithot");
if(hot){
var mouse = krpano.mouse;
var hs = krpano.get("hotspot["+hot+"]");
var hit = hs.hit;
hs.onup = "hit = false;";
if(hit){
var view = krpano.view;
var mouse = krpano.mouse;
var viewx = view.tx - view.ox_rotated;
var viewy = view.ty - view.oy_rotated;
var viewz = view.tz - view.oz_rotated;
var distance = view.dir.x*(hit.x - viewx) + view.dir.y*(hit.y - viewy) + view.dir.z*(hit.z - viewz);
var startx = hs.tx - viewx;
var starty = hs.ty - viewy;
var startz = hs.tz - viewz;
var p1 = view.unproject(mouse.x, mouse.y, distance, true);
var loopid = krpano.actions.renderloop( function()
{
var p2 = view.unproject(mouse.x, mouse.y, distance, true);
hs.tx = startx + view.tx - view.ox_rotated + (p2.x - p1.x);
hs.ty = starty + view.ty - view.oy_rotated + (p2.y - p1.y);
hs.tz = startz + view.tz - view.oz_rotated + (p2.z - p1.z);
});
}
}
krpano.drag3dup = function(){
krpano.actions.stoprenderloop(loopid);
}
]]>
</action>You can see that working here:
test
When you set the capture of the hotspot to false you need to change this (otherwise it behaves strange when you change view values ) :
<events name="rightmousebutton" keep="true" ondown="if(mouse.rightbutton, Drag3DDown());" onup="Drag3DUp();" />
Find that here:
test
My question basically is, why does the first example works in the first place on the rightmouse button?
My brain is a bit cracked 
Obviously you could do something like this quite easily ( i didn't take the effort of making it nice etc.. just tech example):
test
You can shift click a model to rotate it and just click it again to remove the rotation helper.
Tuur
etc etc.. Working on some little projects to show.. but that will take some time.. too many ideas.
