🙂 thanks Dan!

a preview of my project

i have a 3d point control and a circle effect, what i trying to achieve is to link the circle effect.center to the 3d Point. without any 3d Nulls in the scene,
hopefully i can save the preset and use it as an independent 3d circle effect 🙂

however i not able to toComp or use the z values in the 3d point control.

—————————

combining with the beam effect, i was trying to make something similar to plexus plugin, but with auto animation driven by in/outPoints.

it will be a bonus if i could somehow link the z values as a multiplier of the circle’s radius.

now i have a 2d chain of circles with a bunch layers of messy codes :S

the animation goes like: a circle grows into a chain, then eventually the 1st circle will go to the 2nd circle position and vanish, &so on..

ef=2; // index of the 3d Point control
t=.3; //transition time
t2=inPoint+(t*(ef+2));
t1=((ef-2)*t); //offsetting to the next 3d point
v1=effect(ef+7)("Center"); //ef+7 is index of the circle effect
v2= effect(ef)("3D Point");
if(time>=t2) ease(time,t2,t2+.3,v2, effect(ef+1)("3D Point")) else
ease(time,inPoint+t1*((ef-1)*t),inPoint+t1*((ef-1)*t)+t,v1,v2)
// messy but worked :p

thanks Dan,
below is an expression of a shrinking circular spiral –

====================
what i wanted to achieve is a square (or triangle) kind of spiral movement. which looks like this 🙂
will best if the shape of the spiral can be controlled by an angle value Or numOfSides
===================
thank you for your time 🙂

//circular spiral
c=C.layer.position; //center
r=linear(time,inPoint,inpoint+3,300,0); //radius
x=r*Math.sin(time*20);
y=r*Math.cos(time*20);
c+[x,y]
