getlooktodistance for 3D hotspots ?

Hi ,
Is there a similar getlooktodistance action for 3D positioned hotspots (tx,ty,tz) ?
Thanx !

var a = x2 - x1;
var b = y2 - y1;
var c = z2 - z1;
var d= Math.sqrt(a * a + b * b + c * c);

should work to get distance between 2 3D hotspots.

Hi,

not fully sure, but i think the below is already doing the horizontal part quite good.
Busy with something else.
if there is a better way of doing this please share.

Hah!
Nice.

Different use, different math.
Thanks for sharing!

Same use, different maths ;)

By the way your example seems to be false, if you pan around then d value is changing.

hi,

no!
not same use at all.

Quoted

well, besides i am very bad in math, i also just did a very quick try.
As said, busy with something else.
I was also not measuring the distance, this was not clear for me in your first post and tread title.
I was just trying to make the hotspots green when they come into 'range' with hlookat.
So i thought maybe make a pseudo ath for the 3d positioned hotspots.
Totally different approach and use.
I think both are interesting though... also to combine.
I hope to also see good solution for my approach.(better and complete math perhaps)
I'll work a bit on the atv .. later..
