This is part two of the base plate design process, in which the ocean surface is disturbed by a Dreadnought’s bow and stern wave, i.e. its wake.
Several articles on that topic are available on the net, e.g.:
- Donald C. Simon: “Wake Patterns”. http://www.steelnavy.com/WavePatterns.htm
- Planet in Action: “Realistic looking bow waves”. http://www.planetinaction.com/software/shipwake.htm
Dozens of aerial photos of warships can be found on the net, too. In the end I relied on http://www.navsource.org/archives/01/0163027.jpg (USS Missouri taking part in RAS manoeuvre) as reference.
The result of heavy GIMP layers usage, creative gradient application, filter experiments and extensive masking operations (as well as one unsuccessful gnuplot session dealing with Kelvin wave patterns) is shown below:
