Projecting 3D to 2Dcomp
I’ve got 2 circular elements ( A and B ) in 3D-space,
the circles are moving and the camera is moving too.
I want to connect the radius of the 2 circles with a “beam”,To place the start of the beam on circle A I use;
p1=thisComp.layer(“A”).transform.position;
p2=thisComp.layer(“B”).transform.position;
delta = sub(p1, p2);
angle=(Math.atan2(delta[1], delta[0]));
radius=250;
x=radius*(Math.cos(angle));y=radius*(Math.sin(angle));
CO1=sub(p1,[x,y]);
toComp(CO1)If i use this data on a 3D-layer it follows the radius correctly but,
problem is that i can’t seem to project the coordinate to the screen
to get the beam’s 2D coordinate.somebody has a clue ?
thanks
cya,

if you upload a scratch file, I’d be willing to help find the solution.

thanks for the offer,
but I’ve got it solved now.Mylenium pointed me to the “Lensflare” script on Dan Ebbert’s site
(https://www.motionscript.com/masteri…lens-flare.html)
seems like I was “looking” at my script the wrong way. A new view on it helped a lot.fixed it with this:
L1=thisComp.layer("Bol1");L2=thisComp.layer("Bow1");
p1=L1.transform.position; p2=L2.transform.position;
delta = sub(p1, p2); ang=(Math.atan2(delta[1], delta[0]));
radius=269;L1size=900/2;x=radius*(Math.cos(ang));y=radius*(Math.sin(ang) );
L1.toComp([L1size-x,L1size-y,0])cya,
