Re: [osg-users] VPB and OpenStreetMap coordinates problem
Hi Simon, have you checked that there is no systematic offset in your data? Maybe your procedure is right and the data is wrong... It seems your are labeling only summits, so you could search for local maxima next to your label position to get the real summit. Adding a treshold in that search function you could use to to allow such a correction algorith only for summits, not for ridges.

CMake itself is feature rich so the below example just touches on a
very small subset, for your own application it's likely you'll need to
elaborate further. There is plenty of resouces on the CMake websites
to help fill in the blanks.
Good luck,

For example with our own community the current number of subscribers to the osg-users mailing list is 2027, and the number is still on average growing but pretty slowly these days as the majority of new users are joining the forum.openscenegraph.org for support rather than the mailing list. Since the forum and osg-users are synchronized there are really two different halves to the community, so it's propbably approch would be to total the two to get a reasonable figure. We'll need Art Tev's the forum's administrator to comment on present number of subscribers. There is also non english language forums such as the chinnese forum that is huge, but I don't particpate or manage it so can't comment on numbers. A few years back I believe it's size was at least as big as the OSG's mailing list, no doubt it will have grown as well. In the end though I'm not sure what value is in a figure.

I want to put in the scene a ton of them and each container is a PAT node in my scenegraph. I just want to know wich are the best techniques to improve the frame rate in this example. Using lots of seperate box geometries and lots of seperate PositionAttitudeTransforms will leads to a scene graph that has a bottleneck in both cull and draw as there are simply too manage seperate objects. In the case of transform nodes they are particularily expensive for the scene graph to traversal as each transform node requires the view frustum to be transformed into the subgraphs local coordinate frame - we've optimized this as much as we can but in the end a transform node will always be more expensive that just a straight node. As a rule of thumb one can typically scale to having thousands of transforms on screen at any one time without major performance difficulties in cull, but scaling to ten's of thousands will introduce a bottleneck. The osgforest example has one subgraph path that tests the peformance of transforms so have a look at this to see how things scale. Since transform are expensive if you have very large numbers of them it's an obvious one to optimize away. How to do it will depend a great deal on your hardware constraints, the amount of data, whether the data itself is a static geometry, and whether the transforms are static, and just how many objects you have in the scene, whether the geometries are identical etc. Only you can answer these questions so please dive in a bit deeper about these aspects and what peformance you are looking for, what you are getting now.

Re: [osg-users] Optimizing a scenegraph
Thanks Robert for your reply, I'm new with OSG but I think the osgForest example will helps. I will try to explain a bit what I'm looking for. My graph is very simple at the moment. It represents a seaport and I need to work with the containers(leaf nodes in the graph). I want to represent in my Scene the seaport with a lot of containers (about 300.000), but now I'm working with less trying to improve the frame rate. The containers are organized in streets and each street is divided in other structures to organize it until we have the container class to work with it. Each class inherit from Group except the container (PAT). I have this structure: () Group || | | || ()...() Group | | || ()...() Group | | || ()...() Group | | || ()...() PAT (Container) Each container points to the same Geode because they are the same object (a simple box in this case) but using a translate operation. 1st doubt: Is this the best way to organize the scene graph? Am I using too much nodes? 2nd doubt: Best techniques to improve the drawing time? Back Face Culling? PagedLOD? I don't know if I have explained it well or only made it more difficult to understand. Any opinion will be helpful. Thanks!

Re: [osg-users] Render to Texture Question for Integrating Vendor's Flash Renderer

I haven’t had to post to the forum thus far because of the learning environment that the forum content has provided, along with all the various code examples and tutorials available.

One of the other important reasons that we chose to use Scaleform was that it has a C++ code interface to Action Script (Flash programming language) so we can talk directly to the Flash content to update state information and we have significant amounts of Flash content that we can reuse in our project. Here is a bit more background on Scaleform for reference. Scaleform is a product that was recently taken over by Autodesk. It has been used in many games for rendering interactive flash screens into a 3D world, but more often for developing the game setup/information HUD. It is a third party vendor product so there is a cost involve for our project, but it has the capabilities we need. The product has SDK builds for OpenGL, Direct3D, PS2, and several other game platforms so we are able to integrate Scaleform into OSG with the OpenGL build. Scaleform also manages thread synchronization between the render thread and the thread that updates the Flash content state through its own snapshot buffer, so we can easily hook in our network interface to the simulation program that provides system state content updates. I would appreciate it if you would review my previous description on the use of the FBO camera and provide any suggestions you might have. Thanks!

Re: [osg-users] Render to Texture Question for Integrating Vendor's Flash Renderer
Hi Glen, Thanks for the explanation about Scaleform. Given that it's doing OpenGL calls for you you'll need to be mindful of the effect of OSG state on Scalform and visa-versa. The issues of integration of 3rd party OpenGL codes with the OSG is something that has been disucssed a number of times on osg-users so I recommend look into these discussions. I would also recommend getting the integration working in just the main window to start with, you can use osg::Camera in scene as a render to texture camera or just a Camera that just renders directly as part of the main view so you can toggle to use of RTT camera later. Once the simple Camera usage works fine then enabling RTT by assigned a Texture as a colour attachment as set the Camera::RenderOrder to PRE_RENDER. Use of FBO's shouldn't be something you need to worry about too much - you just enable the Camera to use it if you want, as per the osgprerender example. For rendering multiple cameras on different frames you can simply have a Switch above these Camera in the scene graph and toggle them off as you need them. Alternatively you can use a NodeMask on the Camera's to switch them off. Finally a custom CullCallback attached to the parent of the Camera's would enable you to decide whether to visit its children (the Camera) or not. Switching off a RTT Camera only switches off the rendering traversal for that camera, any texture that it renders to will still be valid for any geometry that is rendered with it in the main scene. When toggling on/off cameras you'll need to careful to make sure that a RTT Camera renders to a texture before the first time it's need in the scene graph - this is an obvious requirement, but will need a little planning to make sure it all works coherently.

Is you scene graph all standard OSG structures or do you have your own OpenGL codes integrated? Robert. On Mon, Jun 6, 2011 at 5:02 PM, Michael Rubin mru...@iraxef.com wrote: Thank you very much. I just discovered that as well and I can see the stats display now! However, once I load in my scene, I still see all the bars and lines and transparent rectangles, but all the text disappears. Has anyone run into this before? I thought that maybe my scene rendering disabled GL_TEXTURE_2D on its way out or something like that, which would cause the text to not draw... but I still don't have the solution.

Re: [osg-users] Render to Texture Question for Integrating Vendor's Flash Renderer
Robert, Just what I was looking for...Thanks! I do have a prototype working using an RTT camera which updates a texture on an object in the scene. On your suggestion about minding the state, it did take me a while to work through the interaction between OSG and Scaleform on the state since Scaleform has its own Hardware Abstraction Layer implementation, but I will review the osg-users discussions you recommend to make sure I haven't missed anything. I hadn't thought about placing multiple cameras under a Switch for selecting the correct camera each frame, Greate Advice...and for the advice for using the custom CullCallback. I will let you know how it all works out and a summary of my final solution. Thank again!

[osg-users] [osgPPU] Render lower Resolution with unitOut than wandow / fullscreen
Hi, I would like to render my scene in a lower resolution than the viewport resolution, but want it stretched afterwards. When I scale the texture(s) that are attached to to the camera, e.g. half res, the render output is only half the size ( in x and y ) and placed in the lower left corner, and not stretched over the viewport. Think that with this method: unitOut - setInputTextureIndexForViewportReference( inputindex ) one can tell ppu which unit/texture is the reference scale for the output, but in my pipleine there is no viewport sized texture. Is there another way to tell unitOut to scale its resulting texture to viewport size ? Thank you!

Re: [osg-users] [osgPPU] Render lower Resolution with unitOut than wandow / fullscreen
Hi Peter, you can manually set a viewport for the unit to render it to specific size and position on the output buffer. cheers, art ParticlePeter wrote: Hi, I would like to render my scene in a lower resolution than the viewport resolution, but want it stretched afterwards.

[osg-users] Absolute beginner questions
Hello all, I am a a beginner to all things OpenGL and OSG specifically. My ultimate goal is to take a list of 3d points and plot them out but right now I am just trying to get used to OSG... and it apparently has quite the learning curve. At any rate, if anyone can help me, it would be greatly appreciated. 1. To start off with, then I go into the folder containing OSG and run: cmake -DBUILD_OSG_EXAMPLES=1 I am confronted with output to the extent that I am missing LibXml2, CURL, OpenAL, wxWidgets, Qt3 (I have Qt4 though), JPEG, PNG, and TIFF. Are these fatal errors and where can I go about getting these libraries (a Google search for a lot of them proved fruitless)? 2. Throwing those error messages aside, I opened one of the examples with a Visual Studio 2008 solution file (osgwidetmessagebox.. chosen completely at random) and tried to build. It searches for the lib files, but appends a d to them i.e. filenamed.lib and, thus, cannot find them in my lib folder as they do not exist. I manually went into the Linker settings and removed the d and get hit with a slew of unresolved externals. Am I missing debug libraries or something, what gives? 3. Also, is there a solid beginner's tutorial? The information on the main site seems lacking and not much pops up in Google. This is what I am looking for the most, I reckon. 4. Is OSG even the best option here? I am only using it as my project manager mentioned that other parts of our project were written using it (I am just working on a utility though) and it might be good for consistency's sake to use it. If there is a easier-to-use OpenGL toolkit/framework, I have no qualms with switching.

Re: [osg-users] Render to Texture Question for Integrating Vendor's Flash Renderer
Hi Glen, Have a glimpse of the osgXI project on sourceforge.net. It has an osgFlash absolute layer and two different implementations using Scaleform and gameswf, written by one of my cooperators.

Re: [osg-users] Absolute beginner questions
Hello Basil, First piece of advice, take things one step at a time, it might seem like a lot but it's all easy once you get through it once. Also, you seem to be going at this blind. Do you know about OSG's main site? http://www.openscenegraph.org/projects/osg/ From there, you can follow the Documentation link on the right, and you can click Getting Started to get an intro with Linux/Unix-centric build instructions, or you can go to Platform Specifics and then Windows - Visual Studio to get Windows-specific build instructions. Here's the direct link: http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio 1. To start off with, then I go into the folder containing OSG and run: cmake -DBUILD_OSG_EXAMPLES=1 I am confronted with output to the extent that I am missing LibXml2, CURL, OpenAL, wxWidgets, Qt3 (I have Qt4 though), JPEG, PNG, and TIFF. Are these fatal errors and where can I go about getting these libraries (a Google search for a lot of them proved fruitless)? This is the CMake command-line tool. You seem to be building for Windows (from what you say below) so I recommend you use the CMake GUI because it will give you a list of the available settings you can modify. Until you know what settings you need to modify, the GUI will be a good tool to get your bearings. Next, about those libs it says you're missing. You can get a prebuilt dependencies package for Visual Studio 2008 here: http://www.openscenegraph.org/projects/osg/wiki/Downloads/Dependencies This will take care of the most important dependencies (IMHO the most important are jpeg, png, gif, etc. to be able to load textures from images, and freetype to be able to load fonts to display text). But all in all, most dependencies are entirely optional. OpenAL, CURL, WxWidgets, Qt, etc fall into that category. If you want to use them, you can download binaries or build them from source, and then enter the relevant paths to includes and libraries in the CMake GUI, but until you know you need a specific dependency, you can assume you don't. 2. Throwing those error messages aside, I opened one of the examples with a Visual Studio 2008 solution file (osgwidetmessagebox.. chosen completely at random) and tried to build. It searches for the lib files, but appends a d to them i.e.filenamed.lib and, thus, cannot find them in my lib folder as they do not exist. I manually went into the Linker settings and removed the d and get hit with a slew of unresolved externals. Am I missing debug libraries or something, what gives? If you downloaded the OSG source, you need to compile the whole OSG, not just an example. Here you're trying to compile an example without having compiled OSG itself, so of course it won't find the libraries. This is what I mean when I say to take things one step at a time. You're skipping whole steps by opening one specific example's project file. So, one step at a time. 1. Open the CMake GUI 2. Drag and drop the root CMakeLists.txt (in the root of your OSG source tree) onto the CMake GUI window. This will fill the where is the source and where to build the binaries fields, though I recommend you change the where to build the binaries to some other directory so you don't pollute your source tree. I generally add /build_x86_vc9 or something like that to identify which platform/compiler combination I'm generating project files for. 3. Click Configure a first time. CMake will ask you whether you want to create the build directory if it doesn't yet exist, then it will ask you for which platform/compiler you want to generate. I assume you'll want to select Visual Studio 9 (2008) (x86) or something like that. 4. You'll notice the center part of the window will be full of red fields. First thing to change is to set ACTUAL_3RDPARTY_DIR to the directory where you've put the prebuilt dependencies I linked to above. Then you can click Configure again, CMake will try to find as many of the dependencies as it can by itself. 5. At this point you can change settings as you see fit. Make sure you show Advanced Settings at the top of the CMake window, otherwise some important settings may be hidden, it's an annoying quirk of CMake. If CMake didn't find some dependency you know you have, you can fill in its *_INCLUDE_DIR and *_LIBRARY fields so it will be used. You can check BUILD_EXAMPLES if you want it to generate project files for all the examples. Look over the other options you have, but in the end you can just click Configure until there are no red fields anymore. I highly recommend you set CMAKE_INSTALL_PREFIX to some directory in which you want to put your compiled binaries, again separate from your source and build trees. That way you're sure where the different things are, and you won't get files mixed up between the 3. The directory you specify in CMAKE_INSTALL_PREFIX is the one you'll eventually use when you

Personally I use a debugger and get a strack trace to get an idea of where the crash is and then from this investigate. There is no automagic way of knowing exactly what is causing a crash, nor is there a way of automatically knowing what you are doing with the scene graph that may or may not be causing a crash. If a straight debugger doesn't give you enough clues then you could look at using a memory/thread analsyis tool like valgrind, or an OpenGL debug tool like gDEBugger. Also just observing the app when it crashes and looking to see if there is any correleations that might give you a clue. All it's just dtective work.
