Gerstner Waves - GPU Gems

I’m encountering problems reading the mathematical operators correctly given in this article.

I’m from europe and we have sligthly different math operator signs. Could someone give me the names of the different operators on Equation 9?

Thank you and sorry for the bad english :slight_smile:

I can tell you one of them:

The squiggly line I’m not so sure about. However, user JBaldwin on the forums has already transferred this GPU Gem into Math nodes, you’ll have to search his posts to find it though!

Golden Ratio (Phi)

Well thank you for your reply. Im gonna have a look at them :slight_smile:
