Re: [osg-users] why zlib.dll is miising when execute .exe file
Hi Nan, which version of the 3rdParty package have you downloaded? The current version is V5. You have to added your 3rdparty/x86/bin folder to your PATH. It contains the dll dependencies and has to be part of your path to allow osgviewer to find it. The environment variable OSG_3RDPARTY_DIR is not required to run OpenSceneGraph with this package, it is only available to allow CMake to find your 3rdparty package automatically.

Hi Barry, A number of the OSG plugins support reading from istream, and the tiff plugin is one of them, a quick grep of the source code suggests that the quicktime and imageio plugins also look like do to.

TriangleFunctor reads:

So drawArrays know the data is temporary, thanks to the flag. But shouldn't the

_treatVertexDataAsTemporary = true;
drawArrays(_modeCache,0,_vertexCachef.size());
_treatVertexDataAsTemporary = false;
If you got any clue, that could be nice!

It is identical to 2.8.3, with only the following changes: * Addition of #include iterator in several files (part of trunk r10764). * Replace osgIntrospection Value header nullptr function (trunk r10917). * Fix for OpenThreads INSTALL target (trunk r11354). * Version# bump to 2.8.4. Please note the name change! In our recent discussions of a 2.8 branch refresh, we had referred to this release as 2.8.3.1. However, OSG's version numbers have only three digits, so I've named it 2.8.4. (If we decide to pursue an additional bug fix release, let's call it 2.8.5.)

Re: [osg-users] Serializer bug: not writing double-precision to osgt
I'm on 2.9.9. Sorry, I don't know if it happens on trunk... Do you remember specifically changing the way the serializer outputs doubles in case of an ascii output? It could be because, by default, ostream's operator uses float precision, even if you're outputting a double.

I don't know the specifics of your case, but serializers work for any object subclassed from osg::Object so there isn't any need to subclass from osg::Node. So if you had some custom user data you could subclass from osg::Object and then provide the serializers for this subclass and in theory the serilizers should then output your object.

[osg-users] Alpha blending not working on IOS
Hi All This may be a slightly dumb question but I can't seem to get alpha blending to work on IOS. I've just finished porting my windows code (which works fine) over to IOS but now my Hud Objects alpha doesn't seem to work. The code I use to enable alpha blending on my hud objects is osg::BlendEquation* blendEquation = new osg::BlendEquation(osg:: BlendEquation::FUNC_ADD); m_stateset-setAttributeAndModes(blendEquation,osg::StateAttribute:: OVERRIDE|osg::StateAttribute::ON); //tell to sort the mesh before displaying it m_stateset-setRenderingHint(osg::StateSet::TRANSPARENT_BIN); m_stateset-setMode(GL_BLEND, osg::StateAttribute::ON | osg::StateAttribute ::OVERRIDE); m_stateset-setMode(GL_ALPHA_TEST, osg::StateAttribute::ON | osg:: StateAttribute::OVERRIDE);// just added this now as a test but still no luck I then set the alpha via a material which is already applied to the stateset with m_material-setAlpha(osg::Material::FRONT_AND_BACK, m_alpha); But no matter what I set m_alpha to I can always see the hud objects (even if i set it to zero). I checked the format of my eaglLayer and it is kEAGLColorFormatRGBA8 as it should be. Has anyone used alpha blending on IOS successfully? I could have sworn I have in the past but I've been at this for about two hours now with no luck.
