WAVE EXPRESSION TOOLS

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!

The waves you can create with most of the nodes in

the package are the folllowing:

Random Wave

Triangle Wave

Sawtooth Wave

Sine Wave

Square Wave

Bounce Wave

Depending on your taste the following nodes can be 

downloaded & installed as a package or separately too.

( Instructions can be found in the README.txt in the zip or on GitHub )

WAVE MULTIPLY

With this node you can add 6 different types of wave expressions to the node's 'value' knob. When a certain expression is added

the button turns green.

WAVE SATURATION

With this node you can add 6 different types of wave expressions to the node's 'saturation' knob. When a certain expression is added

the button turns green.

WAVE KEYER

With this node you can add 6 different types of wave expressions to the node's knobs that controls the selected area and set their values separatealy and also to offset them. When a certain expression is added the button turns green.

DIRNOISE

Other than the previous nodes this one doesn't use a wave expression but instead a great benefit of sin / cos algorithms that allows you in this node to adjust the direction and speed of the movement of the generated noise pattern.
