Rotate Car Wheels in Ae With This Expression

Mathias Möhl Shows How to Rotate Car Wheels Using an Expression.

One place where expressions can come in handy is rotating car wheels. Animating wheels by hand can leave room for sliding and have the appearance of loose contact with the ground. Mamoworld’s Mathias Möhl puts basic expressions into action showing how to create the automatic rotating wheel. The tutorial comes as a continuation of the series that teaches primary after effects expressions from the ground-up.

“In this class, we use everything we learned in the previous classes for a hands-on example,” Möhl says. “We develop an expression to rotate the wheels of a car automatically. It works such that you only need to keyframe the position of the car and the expression calculates how the wheels need to rotate to fit to that movement”. The tutorial starts with using iExpressions, but then shows how to write your own expression code.
