I was thinking I'd need a cuboid per floor so I can use textures efficiently. I'm thinking of a texture file that contains a number of horizontal texture strips, each representing a floors-worth of walls for a different building. I think I need a cuboid per floor so they can repeat on the x-axis but use the same texture strip for each floor. Otherwise I need a separate texture file for each different building type, which I understand is particularly inefficient. - partly due to my limited vertex shader knowledge, I was considering doing this with simple meshes (and a single texture for a given region of buildings) - if the geometry is truly fixed, it should sit in a VBO very efficiently, and with no alpha blending or similar, I'd be surprised if the geometry is the bottle-neck.

I was planning something more complicated, with each building being considered separately purely because I could re-use a lot of the code/knowledge I already had from the trees. A single mesh per tile might be a bit much (I think there's a limit on the number of vertices per object?), but certainly a mesh per triangle should work and might in fact be simpler to implement. - if you want to get really fancy, you could set building heights based on the area of the land-cover polygon; small or suburban area = wider spacing, lower heights, huge urban polygon = taller boxes, narrower spacing That's my intention. I'm anticipating defining sets of buildings with heights, widths, textures and spacings on a per-material basis, comparable to the existing random vegetation.

[Flightgear-devel] Jenkins Builds for win32 down?
Hello, I wanted to update FlightGear today. but I noticed that the last win32/64 builds has be created a while ago, though I can see a lot of new things has been added to SimGear and Flightgear since. It looks as currently no win-builds are possible, as OSG, FGRun and TerraGear Builds are missing as well. Anyone knows why?

[Flightgear-devel] FlightGear Newsletter - November 2011
We've just entered the last month of the year, so time for another FlightGear newsletter! This newsletter contains some very important information for contributors, so read it carefully. Altough most of the release cycle will be the same as for 2.4.0, there are some important differences with respect to aircraft. This is our second edition with a contributor interview (thanks Stuart!), and we'd like to continue like that. The idea is that contributors pick interview questions and answer them by themselves. Anyone interested to write next month's interview? You can either send me the interview, or put it in the newsletter yourself. Contributions for this month are welcome at the wiki. But first it's time to enjoy the November edition! -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.

Am 01.12.2011 15:53, schrieb Iervolino Fatima: Hi Thorsten, I've rebuilt all successfully. But I'm still have the same problem as before: What I can do to solve it? First of all, are you really using CMake to configure your FlightGear build (not just for OSG!) - or are you maybe using the MSVC project which is (still) located in the FlightGear folder below project/VC90 ? The latter is unmaintained now - since we switched to CMake a few days ago (see our email topic :) ). I have no idea what happens if you compiled with the now-obsolete MSVC project file. @James/Frederic: Could we drop the VC90 project file now? It's confusing if that's still around. No one is checking this file now, and it's impossible to know what people are using as long as it's still around. Fatima, if you have used cmake for FlightGear (not just for OSG), then check the generated file src/Include/config.h from your FlightGear (build) directory. It should contain: #define ENABLE_YASIM #define ENABLE_JSBSIM = If these were missing (or commented out), then this explains your problem. You could add/enable these defines manually to have a quick success with building. But better also fix the root cause, otherwise issues will be back later. Also check the CMakeCache.txt file (not sure if that has the same name for Windows). It should contain: //Set to ON to build FlightGear with JSBSim FDM ENABLE_JSBSIM:BOOL=ON //Set to ON to build FlightGear with YASIM FDM ENABLE_YASIM:BOOL=ON If these switches are set to OFF (or even missing), then the CMake configuration step hasn't worked for FlightGear. If you can't fix the issue, then please attach the src/Include/config.h and CMakeCache.txt files to your email, so we can see how your build is configured. And remember, these files should be _generated_ on your machine (whenever you run cmake) - so check their file date/time to see if they are really fresh. It may also be a good idea to see if you maybe have any other (old) config.h in one of your include directories - so that the compiler somehow finds the wrong file first... cheers, Thorsten -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
