[osg-users] requestContinuousUpdate not called
I have found the reason why requestContinuousUpdate() is not been called in my application (that is based on osgviewerWX example). The osgviewerWX graphics window is derived from osgViewer::GraphicsWindow (class GraphicsWindowWX : public wxGLCanvas, public osgViewer::GraphicsWindow) and here I correctly add the TrackballManipulator and tried to override osgViewer::GraphicsWindow::requestContinuousUpdate() without success. That is because TrackballManipulator calls, when needed, View::requestContinuousUpdate(). So obviously overriding osgViewer::GraphicsWindow::requestContinuousUpdate(), as I was doing, has no effect. Now I created a class derived from osgViewer::Viewer and here I redefine the function and this now works. But this opens a question: which is the goal of adding a virtual requestContinuousUpdate() to osgViewer::GraphicsWindow? Who calls it? Thanks for your help! mario -- Ing.

Re: [osg-users] Function decoration....
Hi Neil, I'm afriad I don't really have much to suggest on the error you have. You could as an experiment try 2.2, and use the osgProducer library to provide an easier porting path. Robert.

[osg-users] SVN XCode repositoryhas filename issue
This is an academic issue for me, but I thought I'd just pass it along. Having downloaded the entire OSG repository (using the Tortoise SVN tool) onto my home WinXP system, the tool hit a problem when it reached one of the Xcode projects under the Tags (tagged releases) repository. I think this was either the osgProducer_OpenSceneGraph_BranchPoint or Producer_OpenSceneGraph_BranchPoint release, but I can't remember which - it may have been another. Anyhow, SVN gets itself confused because it downloads a filename in one case and then gets asked to download the same filename with some letters in the alternative (upper/ lower) case. This will work ok on case sensitive systems (ie Linux and Apple) but not on case insensitive Windows, where both filenames resolve to the same filename. The result is that Tortoise SVN gives up reporting errors, because it can't create the second file and it leaves things locked. Obviously the lock issue is down to Tortoise, but the filename issue may require resolution, or perhaps this email appearing in the archives may suffice. I'm a WinXP user but have just started a Linux project so get to see the best and worst of both (let battle commence!!!)

[osg-users] Placing camera manually
Hi!
I want to manually place the camera at a point. For that I
have written the following two functions. The second function returns
a view which is added to the viewer. But the problem is that whatever
values I fill in the osg::Matrix::translate(osg::Vec3(...)), nothing
seems to be happening. The view remains the same...
osg::MatrixTransform* setPosition(osg::Node* scene, osg::BoundingSphere* bs){
osg::MatrixTransform* mTop = new osg::MatrixTransform;
mTop-setName(Top View);
mTop-setMatrix(osg::Matrix::rotate(osg::inDegrees(90.0),osg::Vec3(1.0,0.0,0.0))
* osg::Matrix::translate(osg::Vec3(100.0, 600.0, 0.0))); /*All
changes done here*/
mTop-setMatrix(n);
mTop-addChild(scene);
return mTop;
}
osgViewer::View* createTopView(osg::Node* scene){
osgViewer::View* topView = new osgViewer::View;
osg::BoundingSphere bsh = scene-getBound();
cout bsh.radius() endl;
topView-getCamera()-setProjectionMatrixAsPerspective(60.0f,
(double)traits-width/(double)traits-height, 1.0, 1000.0);
topView-getCamera()-setViewport(new osg::Viewport(0, 0,

topView-getCamera()-setClearMask(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

do you have an active motion model, ? Yes, the motion model overwrite each

Hi David, I've had a quick check through View.cpp and the destructor doesn't do anything more than unref the Scene object that should be shared between each of your views, and as such shouldn't actually do anything to the DatabasePager directly.

Hi Robert, i´ll explaing the process we´re following and maybe you can see if we´re doing something wrong we´re using wxwidgets to manage the windows system which is composed by a MDI parent frame and many MDI child frames which all share the same parent frame. each MDI child frame (which is itself a new window) has it´s own openGL canvas and it´s own osgViewer. We also have one global compositeViewer for the whole application. the process we follow for creating each MDI Child Window is, create the new frame, create the new openglcanvas inside the new frame, create a new osgviewer, associate the osgviewer with the canvas using osg_viewer-getCamera()-setGraphicsContext(gl_canvas);, call the SetScene method of the viewer to tell him which scene is going to be shown and finally we call the addView method of the compositeViewer passing the new * viewer as a parameter for deleting the window we first use the composite_viewer-removeView(viewer) and then we delete the wxWidgets stuff, no direct calls to the viewer destructor is used. Does the remoview kills the viewer??? we believe it does because we see no memory leaks when the application closes. we´re not using a ref_ptr in the viewer because we had some problems with the deleting order of the widgets, we´ll try to find a way to use it and maybe it helps a little if you see something which you think is not right, please tell us Date: Tue, 6 Nov 2007 11:20:57 + From: [EMAIL PROTECTED] To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] databasepageloader and composite viewer Hi David, I've had a quick check through View.cpp and the destructor doesn't do anything more than unref the Scene object that should be shared between each of your views, and as such shouldn't actually do anything to the DatabasePager directly.

Re: [osg-users] databasepageloader and composite viewer
Hi David, There a few too many parts in this set up for me to fully understand the ins and outs to it I'm afraid. W.r.t. memory one needs to be careful about ciruclar references i.e. the window owning the viewer vs viewer owning the window. Having the GraphicsWindowWx be handled as a proxy object might be the best way to tackle this, with the WxWidget owning the GraphicsWindowWx and the Viewer's Camera owning GraphicsWindowWx, if the WxWidget goes out of scope then the GraphicsWindowWx wouldn't but would need to be switched off.

Re: [osg-users] removeChild not freeing memory
Yeah I verified through the debugger that the reference count reaches 0. However you may be correct about the memory release...all I've been using to check that is the Memory Used column of the task manager that Windows XP provides. The main reason that I thought the memory was not being freed was that in my program whenever I loaded and unloaded you could see small amounts of memory being released from iteration to iteration based off of some other pointers that were getting deleted, which is why I expected to see a memory drop after a removeChild call. I figured if I saw a memory drop after some other pointer deletions there would also be a memory drop after a removeChild. Is that incorrect? Thx a lot for the help.

I have a program that is loading/unloading model *.osg files on the fly. When I do a removeChild on the model's node, no memory seems to be released. Thus as I load/unload more models the memory used goes up, which will eventually lead to a crash. Just to try this on a simple scale, I went to the osgshadowtexture example since I knew that a readNodeFile call was made to load cessna.osg, and made some small modifications. In the main loop of the program I wait for about 500 iterations after the readNodeFile call, and then I remove all of the children from the node called model in the program. This obviously succeeds because if I continue running the example the default blue shows with all models removed. Unfortunately, no memory gets freed. Shouldn't the memory used go down after that though? Even if I wait for multiple iterations after the removal the memory used does not go down. Is there something blatantly wrong with what I'm doing? If so could you tell me what I need to do in order to free the memory that was taken up by the loading of the cessna.osg?

Any ideas how to prevent it from happenning? thanks, Guy ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] CompileContexts problems
Hi Serge, I have no experience of using this feature under Windows so I really can't provide any direction.

Re: [osg-users] HDR - RGB8 vs RAW
Thanks for your reply David. My results seem unaffected by whether I use an ivec4 or the float version of vec4. I used ivec4 because the author of renderwriterhdr.cpp left commented shader code for the conversion from RGBE to float with the ivec4. Check out readerwriterhdr.cpp line 80 to see what I'm talking about. I am in fact using RGBA8 textures. At first I suspected that no filtering was being applied so I tried using osg::Texture::NEAREST with the RGB8 LDR texture for comparison. Although it became more blocky looking as expected, it still look reasonable. This is in sharp contrast to the RAW texture which shows dramatic artifacts. For quick reference: RGB8: http://img162.imageshack.us/img162/8467/hdrrgb8rn7.jpg RAW: http://img206.imageshack.us/img206/8574/hdrrawza9.jpg Any insight is appreciated, Michael Guerrero ( Delta3D ) From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Spilling Sent: Tuesday, November 06, 2007 1:59 AM To: OpenSceneGraph Users Subject: Re: [osg-users] HDR - RGB8 vs RAW Michael - With the option RGB8 ( osgDB::ReaderWriter::Options( RGB8 ) ) o The image is converted to LDR before being stored in a texture. Doesn't that defy the whole point of being HDR to begin with? Yes, although it allows you to at least read in RGBE / Radiance format files, so that you can use HDR assets in LDR pipelines. That's one thing we fall back to - we generate and ship all our assets in HDR, but depending on the eventual hardware, it may fallback to an LDR load if the card can't handle it. The problem is that my rendering results are different. Firstly, why ivec4 in the textureRGBE code? If you try just vec4 does it get better? I would have thought you wanted floats here... Secondly, could this be an interpolation issue? Is the texture format RGBA8 or 32F (I would have thought that you would be using RGBA8, but you never know). Most of the hardware we support doesn't support LINEAR interpolation on float textures, so we have to do it by hand, as it were.

[osg-users] OSG_MAX_TEXTURE_SIZE
Hi Robert -- I'm in the middle of writing an environment variable reference, and I'm a little confused by OSG_MAX_TEXTURE_SIZE -- what its for, when it has an effect, etc. As near as I can tell, it overrides the _maxTextureSize member variable for both Texture and Font, but only if its smaller than the current value (which, I assume, comes from OpenGL). However, _maxTextureSize itself only appears to be referenced if non-power of 2 textures are not available, in which case it's used in the computation to determine the maximum power of 2 dimension for the texture during resize. Am I missing something here? Why would a user ever set this? Thanks. Any additional info will help make this a better document. :-) Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com http://www.skew-matrix.com/ 303 859 9466 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] DatabasePager -- dead code?
Hi Robert -- DatabasePager has a method getMinimumTimeAvailableForGLCompileAndDeletePerFrame(), which returns the value of the variable _minimumTimeAvailableForGLCompileAndDeletePerFrame.

[osg-users] DepthBuffer grid
Hi, To start, I am grabbing the depthBuffer from the video card using the readPixel (0, 0, width, height, GL_DEPTH_COMPONENT, GL_FLOAT) method. First, I will create a camera that will be positioned above the scene's geometry and point straight down. I'd like to take the data from the depth buffer and transfer it into memory. Next, using the data, I'd like to create a grid and translate all the depths to height above geometry. If I have an osg::Image *depth_buffer, I believe that: depth_buffer-data() takes the depthbuffer from the video card into memory. How can I store all the data into an array, iterate through it, and convert the normalized values into meaningful height values? This is an e-mail from General Dynamics Land Systems.

Re: [osg-users] PickHandler Class on Quick Start Guide
Hi, there, Paul. I have tried to adapt your PickHandler class to solve my specific problem, but I couldn't. Please, help me out. Honestly I haven't completely understand it (when you check for Intersections and stuff like this) but I imagined that all I had to do was to put my own methods after the if (_selectedNode.valid()) condition. Well, let me elaborate a little bit more on my software's current situation. There is a Point class, that is osg::MatrixTransform's daughter. Each Point's instance has a geode child, which carries a sphere with a certain color. What I need to do is change the sphere's color after this shape was selected by mouse picking. I've tried creating a method changeColor, that belonged to the Point class, and I've made the PickHandler a daughter of that class, so that it would have access to the method. Specifics of the method aside, what do I have to do to call that method? Is it simply by writing _selectedNode-changeColor(); in the above mentioned condition's nest? That doesn't seem to work very well Do I have to declare _selectedNode as a global variable before the definition of the class? If yes, what kind o pointer would it be?

[osg-users] Tank Traversing across terrain
Hi, I'm trying to make a tank move across a terrain. The terrain is created by reading the image files of Puget Sound that i downloaded from http://www.cc.gatech.edu/projects/large_models/ps.html as mentioned in the quick step-by-step guide for OsgDem. Then I setElevationLayer and setColorLayer to an instance of osgTerrain::TerrainNode. The terrain seems to display fine. I added a "tank" node and attached it to a PositionAttitudeTransform. To make the "tank" move, it is set to a callback whereby it sets the new position of the tank to make it look like it is moving in a circle. The callback needs to check the elevation of the terrain so that the tanks "moves" according to terrain, so to do this I used the function "computeTerrainIntersection" from the example osgparticleeffects. Problem is, computeTerrainIntersection doesn't seem to be able to detect the elevation. I stepped through this function and it seems that osgUtil::IntersectVisitor doesn't seem to get any "hits". I did notice however that if I build the terrain by setting its elevation using osgHeightField as is used in the example osgparticleeffects, the elevation can be detected just fine. How do I make the function "computeTerrainIntersection" return me the correct elevetion? Thanks in advance for your help.
