calculating a vector to angle with expressions
Hi
I want to make a background for an animation with the cc sphere effect. to make things more complicated i want to connect the camera rotation with the rotation parameters of the cc sphere effect. I used point of interest to animate the rotation it o I need a script to calculate the rotation. Here’s my try. (Its not working properly):
x =thisComp.layer(“Kamera 1”).transform.pointOfInterest[0] – thisComp.layer(“Kamera 1”).position[0];
y =thisComp.layer(“Kamera 1”).transform.pointOfInterest[1] – thisComp.layer(“Kamera 1”).position[1];
z =thisComp.layer(“Kamera 1”).transform.pointOfInterest[2] – thisComp.layer(“Kamera 1”).position[2];wx = radiansToDegrees(Math.atan2(y, z));
wy = radiansToDegrees(Math.atan2(x, z));
wz = radiansToDegrees(Math.atan2(x, y));[wx,wy,wz]
It would also be nice if the background would react to the camera movement.
It doesn’t have to be realistic just to add some depthAny ideas?
with best regards

Why don’t you parent the camera to a null and then use the null’s rotation as a direct expression to the cc sphere?
It should work, and it’ll be MUCH less complicated. -
I already tried this but it doesn’t work. Parameters keep constant on the Null-Layer.

yes. i’m aware of this. It’s just for some abstract background. I’m using the inside option so it looks like you’re inside the sphere.
