Comment on Tourist Trap II by eriban

To be honest, parabolas would probably work just as nicely. I expect the difference to be too subtle to be noticeable. However, if you have the option to match reality more closely (the catenary code was out there for the taking), why not? That's one of the things I like about 3D modelling. It triggers you to investigate the things you try to model more closely. For example, my Rock The Boat image forced me to look into the waves that ships leave in their wake, which was an interesting topic.

And yes, there's a shark lurking in the sea. It's patiently waiting for tourists who are keen for a view...
