Only show an object when the camera is within 45 degrees of it?
Hi all, 🙂
I want to fade in a series of images when the camera is within 45 degrees of facing them. I’d also like it to fade-in the image the closer you are to facing them – so 45 degrees away or more would be 0% alpha and 0 degrees (directly facing the image) would be 100% alpha.
Can anyone help me with this??

This should do the trick:
C = thisComp.activeCamera;
v1 = toWorldVec([0,0,-1]);
v2 = normalize(C.toWorld([0,0,0]) – toWorld(anchorPoint));
angle = radiansToDegrees(Math.acos(dot(v1,v2)));
linear(angle,0,45,100,0)Dan
