  1. That's the British three-decker of Trafalgar fame, not the French two-decker, though
  2. Girlfriend is coming with me, so anything with the word 'maritime' in it is not going to happen, unfortunately. Unless it´s a nice boat to of the islands around Athens No idea if it can be implemented, but I have to redo the hull anyway. When I first started on her, I knew next to nothing about french shipbuilding of the time and that led to some serious mistakes down the road which I only discovered when the ship was pretty much done. The biggest mistake was that I took the british 'as taken' plan as gold standard without comparing it to original french plans of similar ships. In other words, I pretty much skipped the research part of this tutorial. One example: Left is the 'as taken' draught of La Renommée, right is La Panthére. Let´s compare it to french plans made at Brest from 1740 to 1747: Left is La Palme, middle La Medée, right an 'idealized' version of La Renommée. Notice how much more fluid the lines are around the wales area on the french plans? They certainly don´t have this 'bulge' of the british plans. The problem is how is how this plans were taken of. British clerks measured the ships at hundreds of points to get enough data to transfer into a plan. To get the body plan, they took measurements on the outside and inside of the hull, then subtracted the thickness of the planking to get the actual shape of the frames, but they substracted a uniform thickness (that of the planks under the waterlines) along the frames, which isn´t quite correct for the wales area and the upper works, because the planking is thicker around the wales and thinner on the upper works. For them, it wasn´t much of a problem, because they were primarily interested in the shape of the underwater hull, for which this type of plan making is entirely correct. But if you want to make an accurate model of the whole ship, then you have to adjust the lines above the waterline a bit. Interestingly, the british didn´t take this into account when they built the 30 or so sloops that are based on the lines of La Panthére. They all have this bulge above the wales. For example, the Myrmidon of 1781 http://collections.rmg.co.uk/collections/objects/83621.html
  3. Bon, donc il est décidé...La Panthére. First part of the hull tutorial will be up next week when I´m back from Athens
  4. Coming soon Checking plans for distortions and getting it into Blender added to the OP. One question: Should I do the hull modelling tutorial with La Panthère or with another ship? These two might also be interesting: The first one is Winchelsea (1764), a Niger-class frigate, the second is La Medée (1741) , the first 'true' frigate which had an important subsequent cruiser design.
  5. This is the successor of my other tutorial, 'Reading a ship plan' and the second of four tutorials (basic hull modelling and basic texturing are next). I´ll take a ship I´ve already modeled as base for this tutorial, the frégate légère La Panthère (HMS Amazon in british service) of 1744. Part 1: Research The first thing you want to do if you found an interesting ship you want to model is to find as many background information on it as possible because it makes the actual modelling much easier. In my case, I found a plan of La Panthère in Boudriot´s 'History of the French Frigate'. It´s not the original french plan (which sadly doesn´t exist anymore according to CATALOGUE DES PLANS DE BÂTIMENTS À VOILES CONSERVÉS DANS LES ARCHIVES DE LA MARINE, probably destroyed by the disastrous fire in the Brest dockyards in 1746), but the plan the british made when they took off their lines after her capture in 1745: The original plan would have been better, as 'as taken off' plans sometimes contain errors. For example, the british plan for La Renommée shows more tumblehome than the original french plan, probably because the thickness of the whales wasn´t properly subtracted when the frames of the body plan were drawn. So, we got the plan from the NMM, now we look for other sources, the best sites are https://digitaltmuseum.se, http://www.maritiemdigitaal.nl/index.cfm?event=page.collections&collection=technischetekeningen and http://www.orlogsbasen.dk/base.htm / https://www.sa.dk/ao-soegesider/da/other/other-collection/40. I was pretty lucky as all three of them have a copy of the british plan of 1745, so I could check each plan for distortions/inaccuracies etc. As it turned out, the plan from the danish archives was the best: It has a few oddities, but more on that later. So, next stop: more research Sister ships, date of launch designer/constructor, dimensions (very important for scaling in a modelling app), service history etc. The best site for the first basic research on a ship is threedecks.org. It shows two entries, one for La Panthère and one for HMS Amazon. I have a danish copy without a scale of the british plan, so I checked the dimensions of Amazon to see if the numbers on the plan are correct: length p/p 115' 6'' breadth moulded 31' depth in hold 10' 2'' The numbers seem to be identical (I also checked the source for the dimensions, British Warships in the Age of Sail 1714 - 1792, just to be safe :P), so we can move on and have a look at the other information on threedecks. The next most important info is who built the ship so we can look for possible sister ships. In La Panthère´s case, that´s Jaques-Luc Coulomb, sous-constructeur under Blaise Ollivier at Brest at the time the plans for La Panthère were made. As it turns out, he also constructed the frigate La Siréne, launched in 1744 ( the plan for La Siréne can be found in af Chapman´s Architectura Navalis Mercatoria). Next I searched threedecks for other ships built at Brest at the time between 1740 and 1750 and which are roughly comparable in size. This brought up ten ships, the most important ones are La Renommée and L' Aramante because there two detailed monographs available about these ships which would be incredibly useful for stuff which isn´t shown on the plan like masts, interior, paint scheme, deck layout etc. And monographs also mean that there´s a high probability that there are models which can be used as further references. This is especially crucial in my case, as I haven´t found any contemporary depictions of La Panthère/Amazon (paintings, drawings, models) which would have been a very important guideline for the modelling process. My next research step, the (service) history of the ship, isn´t that interesting for this tutorial, so I´ll skip that. Part 2: Preparing the plans in an image editor Now comes the interesting (and most tedious) part. I´m using GIMP for this kind of work, but any decent image editor would do. First, we have to determine which lines have to be 'straight' (or better, parallel to the borders of the image), so we can rotate the image accordingly if they aren´t. The red lines (the center of the bodyplan, the center of the half breadth with the waterlines, the perpendiculars fore and aft and the station lines) should be straight on any plan. If they aren´t, you have to rotate the image (GIMP shortcut: shift + R). Only one of the green lines ( waterline and keel) can be perpendicular to the station lines (except if there´s no difference between the draught fore and aft, but those cases are exceptionally rare) Let´s have a closer look if the lines are straight of if we have to correct the image. First the body plan: The blue lines are a nice visual aid (called 'guide' in GIMP) which can be accessed by left-clicking (and holding) on the pixel-scale at the top and the left of the window. As you can see, the center line of the body plan is slightly off, so we have to correct that. To do so, we select the body plan (R), then we cut and paste the selection. In the the layer window, we right-click the 'floating selection' and select 'to new layer'. Now we've created an new layer that can be moved/scaled/rotated independently from the rest of the image. Pressing R will bring up the rotate window: Looks much better after rotating: The keel also is slightly off: We select the sheer (the side view of the ship) and repeat the procedure we did with the body plan: select, cut, paste, rotate. The same goes for the half breadth. Now that the lines that should be straight actually are straight, we have to bring the body plan on the same level as the sheer (shortcut: M to move a layer) I used the dotted line (which shows the inside of the planking) over the keel on the sheer to align the body plan with the sheer. Edit: Jeeeee, I almost forgot one of the most important parts: CHECK YOUR PLAN FOR DISTORTIONS! First, we'll have a look at the sheer and half breadth. Drop a guide an every station line, and measure the distance between them. It should be roughly same for every part between the two purple lines (expect for the two in the middle). My measurements vary between 223 pixels and 225, which is really good considering the plan is over 250 years old. The sheer seems to be okay. Next, the body plan: We measure the distance between the line in the center and the lines at the sides, logically they should be the same. Green line is 678 pixels, red one too. Excellent *insertMrBurnsgrin* Then we compare these measurements with the length of the extreme breadth of the half breadth: I got 677 pixel, which is very much okay This step is very crucial if you want to model a ship from the Architectura Navalis Mercatoria from chapman.net, as these plans are compressed along the longitudinal axis, so the red and green lines on the body plan are much shorter than the corresponding lines on the half breadth. Dividing the measurement of the half breadth by the measurement of the body plan gives you the ratio by which you have to adjust the width of the image. Part 3: Setting up the plans in an 3D modelling app (Blender) So, finally, the plan is ready, let´s get it in Blender: Set up guides to make selecting the various parts of the image easier and more exact (the select tool snaps to the borders of the guides). Corresponding colours should have the same length, the blue line should should be have as long as the red one. The red part for the body plan is 1500x1500, sheer 6000x1500 and half breadth 6000x750. Now it´s just a matter of selecting the various parts and pasting them as a new image. Only the half breadth requires additional steps. This is how it should look like: Go to the image tab and select canvas size. Double the height and move down the image in the preview picture. It should look like this: Then press ctrl+A, right click and select copy, right click again and select paste as..., then select new layer (not paste or paste into!). This the result: Almost there...now go to the layer tab, select transform ---> Flip vertically. Et voila: BLENDERTIME! Open up a new scene and select the cube, go to edit mode and select length in the mesh display/ length info. We have a length/width picture ratio of 4:1, so we have to adjust the length of the cube to 24'. Then we delete the top and the right side of the cube and invert the faces: Then we assign a material to each remaining side of the object. Select one face and press the corresponding view shortcut on the numpad to have a direct view on it: Press U and select Project from view (Bounds). Open up UV/Image Editor in another Window. Go to the texture tab, select New, then Image -> Open and select your image (the sheer plan is my case). This should be the result: Repeat this for the other views/images: Now it´s time to make some virtual sawdust
  6. Recommended reading for new Captains

    Just read Anatomy of a Naval Disaster: The 1746 French Expedition to North America, great book! It´s a very detailed account of the events of the d'Enville expedition with pretty much every data you can possibly want (ships lists and rolls, death rates on specific ships etc), but it´s not 'dry', it captures the human drama of the expedition very well, both for the officers and the sailors; d'Enville - most probably - got killed by his own doctor, his successor tried to commit suicide, the horror of the journey back to France etc. And our La Renommée plays quite a prominent role, too, as she was the workhorse of the expedition
  7. Rename Wasa ship

    Kronprins is a title, like crown prince or dauphin (the heir apparent). The port/dockyard was called Karlskrona.
  8. Rename Wasa ship

    Technically, it´s the Kronprins Gustaf Adolf-class, the ten ships of this class, launched between 1782 and 1785, were 4' longer than the Wasa and were rated as 64-gun ships (Wasa 60)
  9. Player-selected ships 2017 - Initial poll

    Well, one way to get more community-built ships would be to install a 'shipwright commitee' like PotBS had in the beginning - with a dev and community members who already got a ship in-game and know what they talking about when people asked questions on how to model certain things and to guide the development of work-in-progress ships by members. PotBS got a lot ships that way, there just has to be the possibility of direct interaction between aspiring modellers and the devs.
  10. Player-selected ships 2017 - Initial poll

    To the two people who voted for Le Sceptre and the Niger-class: you got taste Here´s a model of the pretty similar Téméraire of 1748 (not the Téméraire in the poll): http://www.amarsenal.be/05_MM_01_JLT T2a.htm
  11. Duchy of Courland (Ship Identification)

    The ship in your first pic is the Friedrich Wilhelm zu Pferde ☺
  12. Player selected ship 2017 - Suggestions

    They never carried 24-pounders, though. Their designer lost his political mentor and this whole project got kinda shelved (and subsequently both ships never saw action as actual warships). Speaking of 'light' frigates, there´s Thompson´s plan from 1781 for a 38-gun ship with 30 32-pounders. Would this be considered a medium frigate, then?
  13. Player selected ship 2017 - Suggestions

    A french 74 would be nice, but I´d actually prefer one of Ollivier´s designs over those of Sané. Like Le Monarque of 1747: Speaking of Ollivier, we abso-********-lutely need his Le Fleuron in-game
  14. Player selected ship 2017 - Suggestions

    That´s the model of the model of the Winchelsea, though. And if I could choose another frigate by Slade (we already have the Coventry-class Cerberus), I´d pick the Southampton. A ridiculous long active service career with a lot of prizes, had the british king onboard twice and captured a 44-gun frigate shortly before she sank in 1812. But I don´t think another british ship is going to happen anytime soon My suggestion, the danish Friderichsværn :
  15. Danish ships in paintings and drawings

    I removed the spoilers, what a freaking mess. Sorry, guys! the ships on the Roux paintings are traders, so no need for gunports. Cute little things, aren't they?
