Hi Rambabu, you can rotate with the rot pseudoloader like this: osgviewer cessna.osg.0,20,0.rot Regards, Laurens. On Thu, Nov 17, 2016 at 12:41 PM, Rambabu Repaka wrote: > Hi,Can anyone tell how to do the nodes rotation for the osg model like > cessna. > > ... > > Thank

Re: [osg-users] Fwd: Unstable passive stereo on Quadro using Quadbuffer

Hi TianZJ, we have a zSpace screen (closely related to your HP screen), and found that to get stereo working the screen needs a usb cable and the following calls to the zSpace SDK must be made: ZSError error; // Initialize the zSpace SDK. This MUST be called before // calling any other zSpace

Re: [osg-users] [osgPlugins] Problems with .ive loading

Hi Lyubov, in your path you have the unexpanded string "%projectpath%\osgPlugins-3.4.0\osgdb_ived.dll" - that will not work. Depending on how and when this is set you need to fix the expansion: registry keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment Path

Re: [osg-users] Disabling plugins via CMake

Hi Sam, This might not work for all osg specific package find scripts in OpenSceneGraph\CMakeModules, but you should be able to disable packages from the cmake command line: from cmake 3.0 documentation: Every non-REQUIRED find_package call can be disabled by setting the

Re: [osg-users] 32bit DEPTH for RTT

Hi Trajce, maybe this sniplet helps? _textureDepthBuffer = new osg::Texture2D; _textureDepthBuffer->setTextureSize(_width+2.0f*_width*_guardBandPercentage, _height+2.0f*_height*_guardBandPercentage); _textureDepthBuffer->setSourceFormat(GL_DEPTH_COMPONENT);

Re: [osg-users] Vector script out of range

Hi Uma, This seems like a new problem to me. First question - are you sure you link the debug version of your program to the debug osg libraries? Regards, Laurens. On Fri, Oct 7, 2016 at 6:21 AM, Uma Devi Selvaraj wrote: > Hi all, > > Thanks for the reply.I am

Hi all, I have found the bug, and created a pull request here . The bug seems to be introduced 17/8/2010 (osg 2.9.11 and up). Regards, Laurens. On Thu, Oct 6, 2016 at 10:56 AM, Uma Devi Selvaraj wrote: > Hi

Re: [osg-users] Render a huge image (30.000x30.000)

Hi Bruno. The osgPoster example can render very large images by rendering in tiles and gathering the image in software. I am not sure it can do 30kx30k, as the image must be held in (virtual) memory, so you may need a large swapfile. Regards, Laurens. On Fri, Apr 1, 2016 at 4:37 PM, Bruno

Re: [osg-users] [build] When writing my own software and integrating openscenegraph, LNK error is thrown out.

Hi Diwas, as you don't mention it I think you did not create a x64 configuration for your project, the default new project is a 32 bit project. In visual studio in below the menus is a bar with two drop down lists, one with "Release" and one with "Win32", below the Win32 is an option called

Re: [osg-users] [3rdparty] FBX <-> OSG/IVE conversion

Hi Patrik, a quick look into the ReaderwriterFBX source shows no support for LOD at all, so I expect FBX nodes with attribute eLODGroup to be skipped while reading an .fbx file, and osg::LOD to be written as a group (showing all LOD's at once) when writing .fbx files. Regards, Laurens. On Mon,

Re: [osg-users] Viewing Stacked Semi-Transparent Geodes

Hi Erik, the effect you see is caused by your blend function being order dependent, for a good result transparent triangles need to be drawn back to front. Did you set the rendering_hint to TRANSPARENT_BIN (binNumber 10 / binName DepthSortedBin)? like in

Re: [osg-users] segfaults with glDeleteShader

Just a quick remark, I think the warning you see is caused by the State destructor deleting the context's extensions: file src/osg/State.cpp (line 138) in State::~State() GLExtensions::Set(_contextID, 0); I think it caused me problems with loosing the extensions wen a camera was

Hi Olmun, the textures in the ive file do not show because you do not have texture coordinates. The probably did not export from blender. Hope that helps, Laurens. On Tue, Sep 22, 2015 at 1:10 AM, Olmun Hilderbran wrote: > Hello, > > I have created a scene in blender

Re: [osg-users] OSG equivalent of Performer pfSequence

Hi Tony, small note: for what you're doing it might be usefull to take a look at OpenSceneGraph\src\osgPlugins\pfb\ConvertFromPerformer.cpp it has a function to convert pfSequence to osg::Sequence (called ConvertFromPerformer::visitSequence) - seems to me osg::Sequence is a good match. Regards,

Re: [osg-users] Antialising

You still need to enable anti-aliasing for your scenegraph: if (osg::GraphicsContext* context = camera-getGraphicsContext() { unsigned int contextID = context-getState()-getContextID(); if (osg::isGLExtensionOrVersionSupported(contextID , GL_ARB_multisample,1.3)){
