With this tutorial that I prefer to call exercise I hope to give you the opportunity to explore a topic often poorly treated:
The Matrix (not the movie)
The prerequisites are a minimum of knowledge of trigonometry, a little bit of geometry and XPresso. It is not for all, but trust me, it is a simple task.
Since I have received some requests on how to concatenate the Bend Deformer automatically I planned on doing this exercise by providing the project file, so you can see everything in detail without having to write anything. But it would be more interesting to redo from scratch all the things.
