Re: [osg-users] question about CUDA with OSG

Hi Kim, Since you are not telling us what a "Big Size of Terrain" actually means, we cannot see where the problem lies. Usually this is due to a poor structure of the scene graph, missing LODs, etc. It also could be shader bound, e.g. your fragment shaders/tesselation shaders are simply doing

Re: [osg-users] reflection / refraction clip plane

Hi all Here comes my follow up. As you can see in the code snipped above, the clipping plane of the refraction camera is looking in the opposite direction. Since the clipping is done on the graphics card, and the primitives are still in world coordinates, the refraction clipping plane has to b

Hi, First of all I am not familiar with Osg and CUDA I implemented fIight simulation program with osg but If I use big Size of Terrain, The performance(fame rate) of application is not good So I wanna try to apply CUDA to my osg application for improving the performance So what do u guys thi

[osg-users] Handling of Vendor extra in Collada (dae) Reader/Writer

Hi osg-users, I have to support a type of Collada that contain specific vendor profiles. For the moment, osg dae reader handle them with some hardcoded vendor specific profiles : "GOOGLEEARTH", "SCEI" ,"OpenSceneGraph" However, I've got the feeling that each Collada producer defines its own pr

Re: [osg-users] Crash when loading a model

Hi Jordi, Sorry I was skipping this information while reading ;-) So my best guess is wrong linkage too. Hi Sebastian and Kevin, If the model is cessna.osg it shouldn't be to big ;). So check you are not mixing debug/release libraries. Cheers. 2013/9/17 Sebastian Messerschmidt

Re: [osg-users] Crash when loading a model

Hi Kevin, The exception bad_alloc usually is thrown if your memory is depleted. So maybe try a smaller model first, to see if your deploy is correct (VisualStudio debug/release mixing is very dangerous ;-)) If this works, you might want to enable sharing. This is a bit hidden: osgDB::Registry

Hi, I try to start a very simple programm on Win7 with VS10. but everytime it crashes. What did I do wrong? Code: #include < osgViewer/Viewer> #include < osgDB/ReadFile> int main(int argc, char *argv[]) { osgViewer::Viewer *viewer = new osgViewer::Viewer; // add model to viewer.

Re: [osg-users] viewer->getCameraWithFocus() is gone?

Hi, I think I have resolved the problem in the mean time. IIRC the problem was that I was picking during regular mouse events (not the osg ones) which could happen any time during traversals. I believe I fixed it with a mutex around frame() and the picking. That might be suboptimal with regards

Hi? Could you sign with a name so we know how to address you? I don't use Windows or MFC so can't answer specifics on this, though I kinda surprised MFC is still be used after all these years... ain't it time to write portable applications and use a portable UI? W.r.t using OpenGL, I see that yo
