You can do a lot in After Effects with just simple algebra, but you can do more with geometry. After all, geometry is just the math relating to shapes and spatial relationships. These pages will teach you some of the basic geometric functions and relationships, and show you how to use them in expressions in After Effects.
These pages are very much under construction. When finished, they'll cover some basic applications of geometry, such as finding the distance and angle between two elements, generating simple harmonic motion, and more.
