Convex Hull

She'II scrape the hull!

Is the hull breached?

I'm sure the hull is solid.

We're picking up some hull ionisation.

You're a good man, Agent Hull.

Construct the convex hull of this polygon

That crap's gonna eat through the hull.

I'm agent Griffin Hull of the FBI.

I think it's going to eat through the goddamn hull.

He must have put a homing device on our hull.

A polygon that corresponds to the convex hull of another polygon

Select the polygon of which you want to construct the convex hull...

You know, it really kind of looks like the hull of a ship.

In fact, the hull of the canoe is the womb of the vessel.

If you're in China, you might use a rice husk or a cottonseed hull.

They'd been struck by a sperm whale, which had ripped a catastrophic hole in the ship's hull.

So Protei is now an international network of innovation for selling technology using this shape shifting hull.

And so this leopard seal grabbed another penguin, came under the boat, the Zodiac, starting hitting the hull of the boat.

If you actually insulate and isolate the machinery of the ship from the hull, you can reduce that noise by 99 percent.

A fish will move because by changing like this, but our boat is propelled by the wind still, and the hull controls the trajectory.

When Western scientists would join Mau on the canoe and watch him go into the hull, it appeared that an old man was going to rest.

You are laying down in a flexible torpedo, sailing at high speed, controlling the shape of the hull with your legs and controlling the sail with your arms.

You want to be able to do this anywhere in the world and not worry about peak rice hull or peak cottonseed hulls, because you have multiple choices.

And so that's the beginning of Protei, and that's the first boat in history that completely changed the shape of the hull in order to control it, and the properties of sailing that we get are very superior compared to a normal boat.

So, I wanted to know if this was possible to put this at an industrial level, so we made a large boat with a large sail, and with a very light hull, inflatable, very small footprint, so we have a very big size and power ratio.

A normal sailing boat has a centerboard here and a rudder at the back, and these two things are what creates most resistance and turbulence behind the boat, but because this doesn't have either a centerboard or a rudder, we hope that if we keep working on this hull design we can improve and have less resistance.

These are men and women who can sense the presence of distant atolls of islands beyond the visible horizon, simply by watching the reverberation of waves across the hull of their vessel, knowing full well that every island group in the Pacific has its unique refractive pattern that can be read with the same perspicacity with which a forensic scientist would read a fingerprint.

These are sailors who in the darkness, in the hull of the vessel, can distinguish as many as 32 different sea swells moving through the canoe at any one point in time, distinguishing local wave disturbances from the great currents that pulsate across the ocean, that can be followed with the same ease that a terrestrial explorer would follow a river to the sea.
