Re: [osg-users] OSG 3.0.1 on iOS 5
Hi Stephan,
thank you for your reply.
After I compared my project with the iPhone-Example on github, I found out that
the file PerlinNoise.cpp is missed in OpenSceneGraph-3.0.1-zip (which I
downloaded from OSG-Website). This was the reason for the osgUtil-error
mentioned above.
Another point I want to indicate is when main-method look like this:
@autoreleasepool
{
return UIApplicationMain(argc, argv, nil,
NSStringFromClass([osgAppDelegate class]));
}
building of app is failed with this message:
ScopedLock: Parse Issue. Unknown type name 'namespace'.
Parse Issue. Expected '.' after top level declarator
Notify: Lexical or Preprocessor Issue. 'ostream' file not found.
Any idea what this could be mean?
Thank you!
Cheers,
Büsra

Hi Chris, I tested the imageio-plugin on os x 10.7 with an older 32bit build (from Nov 2011) and it works for me. I tested only png and jpg files.

From the user: We have found some image color ordering issue on MacOS Snow Leopard 10.6. We do x86_64 build, with imageio plugin. We set CMAKE flag: OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX=imageio For some reason, for all tested images, color channels Red and Blue were swapped. For instance in RGBA case, we have BGRA image.

Looks like your main-file gets compiled as Objective C only and chokes
about some c++-stuff. Try renaming the file from *.m to *.mm

[osg-users] [osgCompute] Computation on a rendered texture quad
Hi, What does the applyAsRenderTarget function do, and when should I call it ? I have a TextureQuad with a osgCuda::TextureRect on it. The textureRect is updated every frame with a frame from a video. I want to render the quad on the screen and use the same osgCuda::TextureRect in my Computation that is attached to the same scenegraph. The computation only reads from the texture. The problem is that when I call the map function, I get the [osgCuda::TextureMemory::alloc()]: unable to register image object (cudaGraphicsGLRegisterImage()) error. If I don't display the TextureQuad, then the errors goes away. But I need to display the TextureQuad. Do I need to call applyAsRenderTarget somewhere ?? Thank you!

[osg-users] Controlling osgViewer through QScriptEngine
Hello, has anybody tried to integrate osgViewer with a QScriptEngine? I'm currently adding scripting support to a Qt based application and wanted to see if anybody else has experience with it. Currently I see only one option: write a class derived from QObject that has the necessary slots to forward everything to the corresponding Qt functions. A prime candidate for such a wrapper would be osg::Camera or a osgGA::CameraManipulator or possibly a GUIEventHandler. Manipulating the scene graph itself through a QScript should be possible by wrapping the graph in a QAbstractItemModel and exposing this model to the QScriptEnginge. Did someone do something similar yet that could be reused or serve as an example? Any roadblocks I don't see (thread safety probably)? -- Philipp Moeller GeometryFactory ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

There have been a few updates to the serializers/.osgt/.osgb/.osgx support since 3.0.1 so there is chance the problem is now resolved, although as I can't spot a specific bug fix for the type of problem your are seeing this is a bit of long shot. One thing of note is that I don't recall other Windows users using 3.0.1 reporting problems as you've described so there is chance there is something specific about your setup. Trying out svn/trunk is worth trying out either ways as if it does turn out there is bug lurking a fix to this will be made against svn/trunk before it gets rolled out to stable releases. Apart from the issue with displaying some of the 3D models I have noticed that I cannot see any textures I use them in my program. Even the examples provided with OSG do not display any textures. This is likely simply an issue of now having the image plugins that these models require to handle images in them. Is it required to have dependencies like 'libpng' and 'libz' etc. present in the system before building OSG? This are optional dependencies - you don't need them to build the OSG, but if you have models that use formats such as png you'll need the associated dependencies. You can use the published 3rd party dependencies to get the most commonly used external dependencies.

[osg-users] Help: problems of intersectorVisitor with Qtmutex
Hello, My program has an osg::viewer as a view widget of a Qt window. An intersectorVisitor object is initialised at the start of the program. The osg::viewer updates its children nodes as a normal viewer does, and updates the transform matrix of intersectorVisitor at the same time. I make another thread to do call of node-accept(intersectorVisitor), where the node is the root node of osg::viewer. In case that the two processes might conflict with each other I set lock with Qmutex when the osg::viewer updates and when node-accept(intersectorVisitor) is called in another thread. But the result turns out to be wrong. When I let the two processes run freely without locking them, then the result is right. I am wondering what happens here. That is to say, what intersectorVositor will do when it itself is locked or the nodes that it visits are locked. Thank you very much in advance!

I'm trying to gauge how feasible it would be to add this feature without adversely affecting performance. The current frame Stats don't seem too heavy, but they're mainly taking measurements before and after the frame, not counting events that happen during the frame. --J On 02/22/2012 03:22 PM, Buckley, Bob CTR MDA/DES wrote: gDEBugger has the ability to view OpenGL Call history. Can't speak on the performance hit. But, sounds like you need it in the app itself. I don't know of an internal mechanism. However, should be able to easily CASE a thin inlined OpenGL layer with metrics embedded. -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Jason Daly Sent: Wednesday, February 22, 2012 11:35 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Counting OpenGL Draw calls in Stats Hi, all, I'm interested in determining how many OpenGL draw calls are made during the rendering of a frame (counting and storing them as a Stats variable). I'm sure this is possible, but I wonder if it would be feasible to do without significantly affecting performance.

Re: [osg-users] setViewMatrixAsLookAt in Qt
Hi Chris, Can you give a bit more info about what you've tried and why it isn't working? I haven't worked with osgViewerQt before, but it looks like it inherits from osgViewer::Viewer, runs in single threaded mode, and frame() is called by the paintGL method, which is presumably triggered by the QApplication's event loop. In this case, it ought to be safe to set the camera position in other events in the same loop, such as user interaction through the sliders you want to use. What I'd recommend is connecting the sliders via the signal/slot mechanism to a function you define, which reads the value of each slider and creates an osg::Vec3 from them. This will be your eye vector. You also will define the center vector (the point the camera aims at) and the up vector of the camera. To actually get the camera, use ViewerQT::getCamera() (inherited from osgViewer::Viewer). Then make the call to setViewMatrixAsLookAt with the vectors from above. Hope that helps, Tom -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45699#45699 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, Bob, I'm not really interested in any other solutions outside of OSG itself. What I'm considering specifically is adding code to count the actual OpenGL draw calls made by OSG (mainly in PrimitiveSet.cpp) and placing the count into an osg::Stats variable (much like the FPS, update, cull, and draw times, number of groups and geodes in the scene, etc). I'd like to add GL draw calls as a stat that can be queried in code (and conceivably could be put into the StatsHandler display). I'm just not sure whether or not collecting this count would be too heavy for general use. If it can't be done without a driver layer or some kind of non-standard instrumentation (like gDEBugger), then we'd rather just not do it. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
