If it can help you, for all spline types, despite the visual effect, 
there is no influence of one coordinate axis on any other axis.

Also, stick to one kind of spline when learning, you will be able to 
generalize later, but mastery of one type (instead of a small bit of 
many types) is the path that is probably the best.
