There are different typos of wave expressions that can be

useful every now and then during a career of a compositor.

Using these lines of expressions people with a task on their hands

of animating something can be more efficient and more accurate 

than using manually created animation.

​

My go to place for such expressions is the invaluable 

collection by Cameron Carson that I very highly recommend - HERE.

This is a link I always add among the firsts to the bookmarks once in a new studio.

​

He was also very thoughtful and put together an

ExpressionWaveGenerator gizmo too that you can 

download from Nukepedia.

​

So, although using wave expressions is hardly a new

idea I wanted to share my take on utilizing their power.

I found that I often used certain types of these

expressions on certain nodes while not on gizmos.

So, after a while I started to add controllers to the nodes and later

some python buttons too to make it easier to access to different

types of wave expressions. 

​

So here is a collection of them that you can easily download and apply!
