[osg-users] VPB and integrated features

Hi community. I have some small knowledge of VPB and that is from some short experience years ago. Since then, I haven't followed the development ... My simple question is, is VPB capable of integrating features (linear, areal) into the terrain mesh? Thanks as always! -- trajce nikolov nick

Re: [osg-users] Rendering Model in color

Two places where I have personally seen such issues, one from using code ported using an older version of OSG, the other was shader/driver differences between computers. If I remember some methods for setting color were removed moving from version 3.0 to 3.2, and I had some code where the

Hello, I'm the SIGGRAPH BOF moderator. Let me see if I can dig them [Robert's slides] up and send them to you and whomever else wants them. Note: I will send you and Steve Satterfield, Prabhat's slides. He indicated that the slides could be released. His slides are interesting because: 1) It is

Re: [osg-users] design issues

Hi Robert, I am very thankful for every hint, really. These hints are really valuable for optimization. And I found the issue, it was pre/post multiply order of the matrices. I was to avoid the calculus from the nodepath and use the ModelView matrix already available in the CullVisitor. Here is

[osg-users] Scene is transparent when loaded with osg 3.2.0 in iOS

Hi, I'm working on an iOS project and while updating the osg version to 3.2.0 came across this bug(?). I can successfully load files (using IFCPlusPlus), generate geometry and load the scene, but for some reason, when the viewer is realized everything is transparent. I can interact with the 3d

Re: [osg-users] design issues

I don't have time to dive deeply in user projects, I can do quick scans of email and provide quick replies where possible. In terms of optimization I'd say avoiding the inverse matrix might be useful. Using the Matrix.postMultTrans/preMultTrans would also be another optimization step you could

Re: [osg-users] Scene displaced from (0, 0, 0)

Hi Bruno, The home position is set during initialization of the view to the scene graphs BoundingSphere's center and radius. If you want to change this home position then simply use a call along the lines: viewer.getCamaraManipulator()->setHomePosition(...) See the

Re: [osg-users] Loading problem, OpenVR integration

Hi Lorenzo, maybe you want to check out this thread: http://forum.openscenegraph.org/viewtopic.php?t=14222 For me it helped by simply 'parading' all objects in front of the camera at the start of the simulation, this forces the push to GPU needed, as long as the data fits on the card. I don't

[osg-users] Scene displaced from (0, 0, 0)

Hello, I have a 3d scene that I manipulate with a TrackballManipulator, and setup a scene in which all nodes are centred in (5, 1). Now when I try to do use the home() function, I can't see my nodes. But if I center my scene around (0, 0, 0), my nodes appear. Should I use something else

Re: [osg-users] design issues

Thanks Robert, I am aware of it, it is already used in my second snippet. Here it is: (is it done properly?) 1. void MyCullVisitor::apply(osg::LightSource& node) 2. { 3. 4. osg::Matrixd inverseViewMatrix = osg::Matrixd::inverse( getCurrentCamera()->getViewMatrix()); 5.

[osg-users] help for warping

Hi All, I'm struggling with a warping implementation to show a 3D scene to a curved screen. I gave a look at osgdistortion example and implemented a RTT camera just like in that example. So now I have a render to texture camera that generates a texture of the 3D scene. Then a HUD camera with a

Hi Lorenzo, >From your description it's sounds like either objects aren't pre-compiled or that they have been pre-compiled but not yet downloaded by the GPU. In OpenGL there is no way to formally force a GL object to be download to the GPU, it's up to the drive to decide what it does when. You

[osg-users] implement filedialog without using qt

Hi, I want to implement a functionality similar to the QFileDialog in osg (currently 3.0.1). A window shows up, where the user can navigate through the filesystem and load/save files. I haven*t used qt in my application yet and i don't want to use it at all. Is there already a class f.e in the

Re: [osg-users] design issues

Hi Nick, The osgUtil::CullVisitor has the maintains a stack of ModelViewMatrix that it accumulates through the the scene graph traversal, you should just need to get the top of this stack using cullVisitor->getModelViewMatrix(). Robert. On 2 November 2016 at 22:25, Trajce Nikolov NICK

Re: [osg-users] Loading problem, OpenVR integration

Hi Lorenzo, The performance constraints on immersive stereo display systems are pretty well the tightest in graphics, even small glitchs can be lead to unpleasant experience. Couple this with rendering more than twice as much data (two eyes and distortion correction passes) means that you don't
