Get a triangle rotation(x, y, z), from its vertices

What cannot be avoided with quaternions is the brain melting goo that comes from trying to understand them, as they’re not a 4D rotational vector; they’re an axis and a scalar value, except when they aren’t.

They are just a little abstract like some other things in mathematics.

But at least you can look at them, which is not so easy with all mathematical abstractions.

For this purpose I have created the visualization.
