Hey Darby, I have another question…

I’m using a variable to control the FOV. It works great as resizing the comp size automatically adjusts the zoom distance. My only concern now is that when I change the Lens size in the camera settings, nothing changes. Would that be correct behavior of the camera?

Regards,
Brett

Thanks Darby, I really have to buy you a beer sometime soon.

I was away from the computer over the weekend and am only now digesting it, it certainly answers my question… though, now I feel like I need to rethink my end goals with the rig.

Ill keep you updated with the progress

[Walter Soyka] “If you know the camera’s FOV, you can calculate the zoom in pixels as follows:

zoom = thisComp.width/(2*Math.tan(degreesToRadians(FOV/2)));”

Interesting, thanks for your response Walter.

Thats definitely in line of what I’m after, though how can you access the FOV from the expression? If there was a way of that being automated, that would be ideal for this rig.

Thanks again!

Darby you brilliant man, it worked!

I ended up with the below expression….

If you’re ever in LA/or based in LA I’ve got to buy you a beer for that one.

Cheers!

POI = value;
tarActive = thisComp.layer("Controls").effect("Target Active")("Checkbox");
tOffset = thisComp.layer("Controls").effect("Time Delay")("Slider");
t = time + tOffset;

try{
L = thisComp.layer("Controls").effect("Target")("Layer");
POI = L.toWorld(L.anchorPoint, t);
}catch(err){
target = value;
}

if (tarActive==1) {POI} else {value}

Thanks Darby, lightning fast on that response!

That makes sense, I’ll give it run tonight and get back to you with how it goes.

Thanks again!

Hi Ray,

Yes you will be able to use this on your iPad, however it will be displayed like most iPhone App at half resolution. We may possibly release an iPad version in the future.

Best wishes,
Brett
