Scale Effect?

[Dan Ebberts]

Try this:


mouse_layer = thisComp.layer("mouse layer");
beginScale = 100;
endScale = 1500;
beginDistance = 40;
endDistance = 0;

w = thisComp.width;
p0 = value + 30;
camPos = [w/2,thisComp.height/2,-50/36*w];
v = normalize(camPos-p0);
dis = length(position, mouse_layer.position);
val = ease(dis, beginDistance, endDistance, endScale, beginScale);
p0 + v*val


If you had a camera in the comp, you would use its position instead of the calculated position.

I wasn’t sure what the +30 is for, but I stuck it in there.

Thank you Dan, its working nice.

One more thing is that all the objects are following the same Z distance, it should be also calculated according to where that object X position is (close or far from the camera), So the object on the very left and the very right should move a longer Z than the one in the center.

I tried to add this.x to each object’s (endScale) but I ended with that the very right crosses the most distance.

Thanks again.

I don’t have time to test it, but try this:

mouse_layer = thisComp.layer("mouse layer");
beginScale = 100;
endScale = 1500;
beginDistance = 40;
endDistance = 0;
w = thisComp.width;
p0 = value + 30;
camPos = [w/2,thisComp.height/2,-50/36*w];
m = length(camPos,p0)/camPos[2];
v = normalize(camPos-p0);
dis = length(position, mouse_layer.position);
val = ease(dis, beginDistance, endDistance, endScale*m, beginScale);
p0 + v*val

Thanks guys, you are amazing..

Everything is fine unless that is goes in the opposite way not toward the camera as it was before..

What value I should add a (-) to?

This is the current code:

mouse_layer = thisComp.layer("mouse layer");

beginScale = 0;
endScale = 2100;
beginDistance = 600;
endDistance = 0;

w = thisComp.width;
p0 = value + 30;
camPos = [1440,540,-2240];
m = length(camPos,p0)/camPos[2];
v = normalize(camPos-p0);
dis = length(position, mouse_layer.position);
val = ease(dis, beginDistance, endDistance, endScale*m, beginScale);
p0 + v*val

Thanks Dan..

I tried on the camera, and the Z but still not.
