// Another serious limitation is more subtle. In the 2D examples above, it is obvious how to connect the

// to make a valid object is to have no points at all on the Y=0 line, and of course none on Y=1. In this case, the resulting texture produces
// a collection of disconnected objects. Note that the Z coordinates of your tile can be anything, but for the dimensional settings on textures
// to work intuitively, you should construct your tile so that Z ranges from 0 to 1.
