After Effects Mini Assignment 3 — Interaction Design Lab

For our third mini-assignment, we were tasked with creating two custom After Effects animations. One that utilized a scrolling script and another that utilized a 3D simulation.

To achieve this, I created the animations below.

I will take you through the steps to create these animations.

For the scroll bar mini assignment, I took the following steps:

Step 1: Create a start and end position for the scroll bar.

Step 2: Create a slider and its associated keyframes.

Step 3: Add the position expression to your Illustrator file. Replace with your Illustrator file. Multiple that file by the percentage you are scaling your file.

slider = thisComp.layer(“control”).effect(“Slider Control”)(“Slider”);
[value[0],linear(slider, 0, 500,footage(“”).height*4.76/2, -(footage(“”).height*4.76/2)+thisComp.height)].

Step 4: Add an object layer for your scroll bar. Add the below position expression to that layer

slider = thisComp.layer(“control”).effect(“Slider Control”)(“Slider”);
B=thisComp.layer(“beginning and end Ypos of scroll bar”).effect(“bigining point”)(“Slider”);
E=thisComp.layer(“beginning and end Ypos of scroll bar”).effect(“end point”)(“Slider”);

For the 3D simulation mini assignment, I took the following steps:

Step 1: Add your footage. Create a mask, pre-compose, and track the camera.

Step 2: Create shape layers to be your path markers. Make them all 3D layers. Mess around with their perspective to match the perspective of the road.

Step 3: Create text layers to provide your desired experience. Make them 3D layers. Change their perspective to your liking.

By clapping more or less, you can signal to us which stories really stand out.
