[osg-users] [build] Issues compiling fx and Cg using collada dom
Hi, I was trying to compile Collada-Dom on Ubuntu.For this i downloaded collada-dom-2.2.zip and compiled the same as per the instructions given on http://www.openscenegraph.org/projects/osg/wiki/Support/KnowledgeBase/Collada; for linux. But when i do make os=linux project=minizip the compiler compiles for make os=linux project=minizip -C dom and make os=linux project=dom -C dom but throws an error for make os=linux project=fx -C fx. Also it gives an error saying that Cg/cg.h: No such file or directory. So just wanted to cross check if fx and Cg are really required.If yes,for what purpose are they required. Thank you!

Re: [osg-users] osgBullet: Stereo mode / TriMesh Collision Shapes
To the stereo mode issue: This morning I had a quick look at the colladaread example in osgBullet. I just set OSG_STEREO to ON and I am getting quite the same picture in the colladaread example like in my environment. The distance between the left and right eye images is wrong somehow misbehaves..

[osg-users] how to get the new position of a PositionAttitudeTransform?
Dear list members,could you please help me with the issue how to get the position of my object?I have developed a class, which is derived from the class "PositionAttitudeTransform" and this class encapsulates within its constructor some other classes/objects. These are namely "Switch" (to be able to set all children on or off), Geode, MatrixTransform and other.My intention is to have a sphere that can be dragged in 3 dimensions by the "TranslateAxisDragger" and to get its new position. So far so good, the visualization of the sphere and of the dragger is successful and I also can drag the sphere around, but I cannot get the new position. I try to get the position with this-getPosition(), where "this" is an object of PositionAttitudeTransform, the result is always zero. I guess the parent class, derived from PositionAttitudeTransform does not get to know the changes of its children. Can you tell me how can I achieve my goal?I thank you in advance.kind regards,VitaliHere is the code of the constructor: TargetSetter::TargetSetter(Rcs::RHCPrimitive *primitive) : osg::PositionAttitudeTransform() { // store the pointer to the RHCPrimitive class _primitive = primitive; //root = new osg::Group; _switch = new osg::Switch; addChild(_switch.get() ); // create a command manager cmdMgr = new osgManipulator::CommandManager; osg::ref_ptrosg::Geode geode_1 = new osg::Geode; osg::ref_ptrosg::MatrixTransform transform_1 = new osg::MatrixTransform; osg::ref_ptrosg::TessellationHints hints = new osg::TessellationHints; hints-setDetailRatio(2.0f); // draw a sphere osg::ref_ptrosg::ShapeDrawable shape; osg::Vec3 position; float radius = 0.01; arr vec= _primitive-computeX1(); // get the coordinates of the initial target (can consist of more than 3 elements) // assuming that the first 3 elements of the vector are x,y,z coordinates position[0] = vec(0); position[1] = vec(1); position[2] = vec(2); shape = new osg::ShapeDrawable(new osg::Sphere(position,radius), hints.get()); shape-setColor(osg::Vec4(0.8f, 0.8f, 0.4f, 1.0f)); geode_1-addDrawable(shape.get()); // draw info text beside the sphere CoordText = new osgText::Text; CoordText-setFont("fonts/times.ttf"); CoordText-setCharacterSize(radius*4); CoordText-setPosition(osg::Vec3(position[0]-radius*2,position[1],position[2])); CoordText-setAxisAlignment(osgText::Text::SCREEN); CoordText-setBackdropType(osgText::Text::OUTLINE); CoordText-setDrawMode(osgText::Text::TEXT | osgText::Text::BOUNDINGBOX); char buf[15]; sprintf(buf, "[%2.2f, %2.2f, %2.2f]",position[0],position[1],position[2]); CoordText-setText(buf); geode_1-addDrawable(CoordText); // material osg::ref_ptrosg::Material matirial = new osg::Material; matirial-setColorMode(osg::Material::DIFFUSE); matirial-setAmbient(osg::Material::FRONT_AND_BACK, osg::Vec4(0, 0, 0, 1)); matirial-setSpecular(osg::Material::FRONT_AND_BACK, osg::Vec4(1, 1, 1, 1)); matirial-setShininess(osg::Material::FRONT_AND_BACK, 64.0f); this-getOrCreateStateSet()-setAttributeAndModes(matirial.get(), osg::StateAttribute::ON); transform_1.get()-addChild(addDraggerToScene(geode_1.get(), cmdMgr.get() )); _switch-addChild(transform_1.get()); _switch-setAllChildrenOff(); // hide the target node _pickHandler = new TargetHandler(this); osg::Vec3d pos = this-getPosition(); std::cerr "position: " pos[0] " , " pos[1] " , " pos[2] std::endl;}GRATIS fr alle WEB.DE Nutzer: Die maxdome Movie-FLAT!Jetzt freischalten unter http://movieflat.web.de

Re: [osg-users] setCamera for Viewer
Hi Tom, One wouldn't normally change the viewer's master Camera while the viewer is running, if you do this you'll been to stop all threading, assin an Renderer and the get the viewer to rewire the threading. In you case I would just take the subgraph below your own Camera and then attach this and then copy whatever settings you want across. Robert.

Re: [osg-users] How can I rotate a image
Hi Martin, If you follow the vertexexample closely then then rotation can be simply added (or removed because its already there) to TexMat in TexMatCallback. Look at R matrix in TexMatCallback::operator(). Multiply this R matrix by neccessary rotation. If you don't know what rotation exactly, try 90 or -90 degrees around X, Y, Z axes. After up to 6 tries you will find the one that best suits your need. And you will learn a lot ;-) Wojtek -- From: Martin Großer grosser.mar...@gmx.de Sent: Tuesday, September 07, 2010 1:16 PM To: OpenSceneGraph Users osg-users@lists.openscenegraph.org Subject: Re: [osg-users] How can I rotate a image Ok, also I have create a sky box like the sky box in the vertexprogramm example of osg.

Re: [osg-users] Virtual reality application (head-tracking, stereo, immersive displays)
Dear Lucie, at the Graphics Group at Delft University of Technology we use our VRmeer toolkit, basically some Virtual Reality and Data Visualization extensions combining OSG, VRPN and VTK. You can download our source code for use or inspiration at http://graphics.tudelft.nl/VRmeer The default stereo provided in OSG provides on-axis stereo. To accommodate more better stereo views on your display, we calculate off-axis perspective matrices, for each eye of every head-tracked user based on actual display sizes. We do use the osgUtils SceneView callbacks right now (as indicated in the other posts) , but it seems this is deprecated and I plan to convert this to the Compositeviewer.

Just a small note, the way to do stereo at the viewer level would be to use two slave Camera attached to one View(er), rather than two View attached to the CompositeViewer. The master Camera of the View(er) would be controlled by the head tracking, while the eye offsets would be done as projection and modelview offset matrices associate with each slave Camera.

Re: [osg-users] std::vectorbool performance issue
Robert, You are right, although vectorbool is slow, it is apparently not the bottleneck. In my case, the bottleneck was basically, a deep and complex hierarchy of osg::Switch groups. I did some frame rate testing, replace all the osg::Switch with osg::Group, then frame rate tested again. There was only a minor difference. The hierarchy is the issue, not the presence of the osg::Switch Still, this is a bit like the _SECURE_SCL=0/1 issue on Windows - a performance problem possibly waiting to bite someone.

Re: [osg-users] Issue with osgOcean on MacOSX GeForce 7300 GT
Hi Tat, I have been able to run osgOcean by modifying the shaders, but the frame rate was not acceptable (15 FPS). I have also applied the patch to Texture.cpp, but it didn't resolve the FBO errors. Given the framerate is too low, I stop trying to run the software on that graphics card. Thanks a lot for your help.

Somehow some of nVidia drivers omit the cast part and then try to pass an integer parameter to a function (like pow) that requires a float parameter, and thus you get wrong operand types, no matching overloaded function, or undefined symbol. A solution for this is to replace integer constants (like 1, 2, 3, ...) with explicit float ones (e.g. 1.0, 2.0, 3.0, ...) in shader source code. This can be a mac specific issue but it is safer to use float constants in shader code unless integer constant is clearly needed. As long as I don't disable all the options that use a FBO, I get garbage on the screen. Is anybody using osgOcean successfully on MacOSX. Is the graphics card too old for osgOcean? If the graphics card should be capable of running it, any hints on how to fix it are welcome. GT7300 driver on Mac OS X has a problem in hardware mipmapping. So you need to disable it by applying my patch to Texture.cpp. The patch is available at: http://macflightgear.svn.sourceforge.net/viewvc/macflightgear/trunk/patches/OSG-2.9.8.diff?revision=279view=markup # This patch (for Texture.cpp) was once rejected since this hack is too drive specific bug-fix.

Re: [osg-users] Issue with osgOcean on MacOSX GeForce 7300 GT
Bonjour Jean-Claude, I have been able to run osgOcean by modifying the shaders, but the frame rate was not acceptable (15 FPS). I have also applied the patch to Texture.cpp, but it didn't resolve the FBO errors. Given the framerate is too low, I stop trying to run the software on that graphics card. I have used osgOcean on a 7900GTX in the past, and performance was acceptable, but not great. The 7900GTX is the high-end card of the 7000 line, whereas the 7300GT is on the low end, so your results don't surprise me. You could probably get better results if you're willing to lower the resolution of the mesh osgOcean generates. Have a look at the parameters to the constructor of FFTOceanSurface. Plus, you'll probably want to disable all effects (reflection, refraction, silt, god rays, depth of field, etc.) and remove the shaders altogether. Doing this, I have been able to get acceptable performance even on laptop integrated chipsets... Of course then it doesn't look so great, but the client required any ocean representation, and it's better than a blue flat plane. ;-) So if you're willing to do some testing, disabling things and re-enabling them to find your sweet spot, you should be able to use osgOcean on most graphics hardware.

As you can see with the middle chair, the legs seem to be working but then the seats polygon lines get exposed? May this be an issue due to using 2.8.3 ? You need to enable the stencil buffer when you create your graphics context in order for the outline effect to work correctly. If this is not done you'll get the problem you have (sometimes internal polygons are shown, sometimes not, depending on order of drawing). You should be able to use osg::DisplaySettings::instance()-setMinimumNumStencilBits(8); before creating your viewer/window/context to do this, or modify the traits you pass to createGraphicsContext() if you're creating it yourself.

[osg-users] update problem
I have a set of nodes in the scene. I implemented an UpdateCallback class and set it to each node of the scene to animate it. The UpdateCallback implementation basically uses the current system time to get the values of position and rotation from the corresponding array. Now the problem. Since the UpdateCallback of each node occurs at different system time, sometimes happens the whole scene is not updated in synchronous way. In fact during the update visit the index of the array to get the new position and rotation from is different from one node to the previous onces of the scene. Basically I need a way to get the system time and store it somewhere once for every update visit. I thought to derive from the NodeVisitor and store the system time in the constructor (so that I can get it back on every UpdateCallback) but I'm not sure this is possible. I don't know where the Node/Update Visitor is created and if there is a way to set my own visitor instead.
