Animating Spirographby Ashish Rastogi, India
In this tutorial we will create spirograph style animation using any version of Illustrator and After Effects. A Spirograph is a curve formed by rolling a circle inside or outside of another circle. The pen is placed at any point on the rolling circle. Hope you have created lots of spirograph in the childhood.
Step 1: Create a new 1024 x 768 pixels size document inside illustrator and select an Ellipse Tool (L) to draw the circle or any shape you like. Press Shift for creating a perfect circle. Just remember that line color is black and Fill color is transparent.
Step 2: After creating a design select the whole design and choose the rotate tool and by pressing “Alt” key click on the design.
Step 3: This will open a rotate popup dialog, choose 5 degree inside the angle, press Copy and then OK.
Step 4: Now just press Ctrl + D and keep doing to add more overlapping copies to complete your spirograph.. If design goes out of the canvas then select the full design and scale down.
Step 5: When design creation is complete then change the line color of the design to white and save the file in “AI” format.
Step 6: Create a new composition in the after effects sized 1024 x 768 and import the illustrator file.
Step 7: Press R and rotate the spirograph from 0 second to 5 seconds.
Step 8: Enable the 3d layer button and rotate the spirograph in Z axis.
