In this article, Jorn-Harald Paulsen demonstrates how to create a sine function in Maya. It’s possible with many expressions and the nodes method that he will walk through but it will all happen entirely within your computer screen!
Nodes can be a very powerful tool when working in Maya, as the node will evaluate much faster than an expression could. They also happen to be more flexible and give you control over what gets evaluated when – there are rare occasions where forcing evaluations on expressions might not work out so well because they stop reacting to changes quickly enough for our desired output!
Even if you know how a sine works, there’s still something to take out of doing it this way in Maya
