That is going to be interesting. It is years ago that I mused about ship
hulls and the way to make them in POV. I abandoned at that time, turning
instead to the use of: http://www.delftship.net/ which does an excellent
job.
In a simple manner, I did some triangle mesh building in my Gancaloon
series years ago (I need to revisit one day!). I enjoyed to do that and
I learned a lot from the process. So, Do not let us wait for too long ;-)

Here is the result of playing around with vectors and angles.
Looks like a nice round backside.....
Cheers

Yes. There still seems to be a hint of angles in the curve though. Could
to be solved with a bit higher resolution of the mesh.

Or an additional control point near the centre line. If it is a spline.
The ship is coming along. I can almost smell the coal fired boilers. :-)

You could make a "stealth Titanic", full of angles and straight areas in
between. ;-)
Don't take me serious.
But I have another proposal, on the serious side:
if you like the idea, I could give you the source code for my 1850s
river paddle-wheel steamboat, and you can place it beside your Titanic.
I use 1 unit as 1 meter.

I thought it actually looked more natural. They *were* bending and
riveting steel.
I can only find one picture of the stern (lots of drawings of it in the
air though...)

That is indeed true. Lets wait for the completed hull before assembling
the jury again. ;-)

Bear in mind that it is the superstructure not the hull. I would expect
the steel plates to be cut and shaped to a wooden pattern built by
carpenters from drawings for each part.
If you want an idea of what shipbuilding was like 30 years later. Look

This is brilliant! Thanks for the link. I shall put that aside for
future reference/use in some scene or other. Inspiring.
Reminds me of Christopher Richard Wynne Nevinson. One of his paintings
appears on the book cover of David Landes' "The Wealth and Poverty of
Nations". Good read.
