Using the Golden Sprial / Fibonacci Spiral in After Effects

The Golden Ratio / Spiral is a well known and useful tool when designing compositions. It frequently appears in nature which may explain why when we frame shots and images to line up with the spiral we find them asthetically pleasing. You should not feel you always have to use the Golden Spiral – instead it’sjust another tool, like the Rule of Thirds. However, there is no simple way to get it to display in After Effects. And that’s what this video is here to address.

Expressions used:

Radius = effect("Size")("Slider")/145;
X = Math.sin(Math.PI*Radius)*Math.exp(Radius);
Y = Math.cos(Math.PI*Radius)*Math.exp(Radius);
Z = 0;
[X,Y,Z]

L = thisComp.layer("Spiral Null");
L.toWorld(L.anchorPoint);
