yes all this... I only have a problem with realistic turning diameters. So far I only have the data for Type VII. If someone knows any source about the turning diameter of any WWII vessel then please post it here.

It will also come with "realistic" shorelines (200m resolution) including realistic elevation - took about a month to process this stuff to a usable data set.

Ouch - that's why I prefer ugly large but safe cases for my devices - better get one like this (was only 25,- EUR), even the edges are protected:



This button is also the Power Button Can you still turn it on once it's off?

Something like: touch the screen with 5 fingers and a screenshot is made? (otherwise you would always have another GUI button on the screen) I guess I can add it.

My plan is to include the II, VII, IX, XXI, XXIII as playable boats
But some of them later as a cheap in app purchase.

as AI boats: XIV (Milchkuh), some italian, british and soviet boats

That's why I possibly start with the VII only because the work on the interiors takes some time.

I'm currently busy with updating my other apps but I will soon™ return to the development of WOTA and post a new movie.

It IS in a protection case, similar to the one on your photo, but obviously this case did was not good enough. When the iPad is only in standby, I use the round centered bottom button. If it's REALLY off, I can switch it on when using the AC adapter for charging.

For example, yes


Looking forward to read news soon

I've just sent out a new newsletter, so I thought easiest way is to post it here too...



It's time for WOTA News again. Usually I'll post most news regarding the development of WOTA on the facebook page, so this mail is to keep those up to date who don't use facebook but I also added a new movie not shown on facebook yet.

First of all the game world itself was increased. The game will cover the entire planet now. When I processed the necessary geo data I've decided that it's better to do it now instead of adding the pacific later.
The game world has exactly the same resolution that Silent Hunter III uses, I guess they have used the same geo data to calculate their shorelines. The resolution of the terrain is 200x200 meters, this does not sound much, but this also means there are 1.05 billion (!) data cells for the coastline! The terrain itself uses SRTM Data for the elevation, this data was collected by a Space Shuttle Mission in February 2000. Correct citiy and vegetation data are also included in the WOTA geo data set. It took over a month to process all this data from different sources to a new format that WOTA uses. More than 100GB of data had to be processed.

Visualization of the coastlines (Web Mercator Projection):


Final resolution (200x200 meters, picture shows the bay of Kiel):


Visualized sample of the Geo Data showing urban areas around the north sea, looks a lot like satellite pictures of city lights.
(of course only those data close to the coast and rivers is used in the game:



Next huge change is OpenGL ES 2.0! I feared performance would suffer, but I wrote a shader for the water that is still fast and looks much better now, it even the sun affects the water, this was just not possible to do with OpenGL ES 1.x. So WOTA uses Pixel Shaders now which means Ships and other objects will look much smoother and lights will be more realistic.

This is a picture of the new water taken with the iPhone camera from the iPad's screen:



As I've wrote before the minimum requirement for WOTA will be a iPhone 3GS / iPod Touch 3, so it's also time to upgrade the interior of the U-Boat, which was made for older devices, the newer iOS devices can handle more polygons.
I've made a quick test of the lights & shadows for the command room, textures I've used are mostly just a test and will be replaced. The performance on the iPad 1 is just awesome smooth.

Movie of the lights & shadows (as you can see some of the gauges are already round some others still needs to be upgraded):



You will also see small vessels in the game like motor torpedo boats, so another movie which might be interesting is this one, it shows the modified buoyancy & collision system tested on (unfinished and untextured) italian MAS Boats running at full speed.
The water shader you see in the video is outdated, it was the very first OGLES2.0 test.



Still a lot of work to be done till WOTA will be finished, but I am a single developer and all this stuff needs time.

Impressive work!
