Re: [osg-users] how to get the handle of opengl texture that corresponds to a OSG::Texture

Hi Robert, Do you mean the DrawCallback in the Camera class, which contains virtual void operator () (osg::RenderInfo& renderInfo) ? And here I can use the RenderInfo right? As I know, the following code can get a contextID: camera->getGraphicsContext()->getState()->getContextID(); Is this

Re: [osg-users] Oculus+OSG

Hi, I just fixed a performance related bug. Due to misuse of an enum I had accidentally disabled all culling. (This bug would probably been avoided if strongly typed enum a'la C++11 were used). This bug only affects users using Oculus SDK 0.6 and 0.7. I urge all users of these versions of

Hi Robert, I'm attempting to use the latest git build of ffmpeg ( http://ffmpeg.zeranoe.com/builds/). I am going to try with 2.5.2 next. Would it be possible to get ffmpeg added to the dependencies package for OSG? I'll let you know how it goes. Thanks, Sam On Wed, Sep 9, 2015 at 7:45 AM,

[osg-users] pfObject::getNamedUserDataSlot

Is there an equivalent function to the Performer pfObject::getNamedUserDataSlot? Our code uses it a lot to store object data. I'm guessing we could just store the data in a map and uses the slot id returned as a key. Tony V -- Read this topic online

Re: [osg-users] ffmpeg library version expected for OSG 3.2.3

Using ffmpeg 2.5.2 cleans up the compilation issues. I used a precompiled version of ffmpeg which was compiled with a prior version of VS so I do get a SAFESH warning. On Wed, Sep 9, 2015 at 9:26 AM, sam wrote: > Hi Robert, > > I'm attempting to use the latest git build of

[osg-users] [Questio nabout StateSet.cpp] truncated attribute override value?

Hi, Iwould like to introspect StateSet in order to know which override value is activated for a particular stateset. I parse AttributeList for this Code: for( osg::StateSet::AttributeList::const_iterator it=ss->getAttributeList().begin();it!=ss->getAttributeList().end() ; it++) {
