Re: [osg-users] Depth Buffer/Culling Problem with osgViewer CompositeViewer
Hi Rob, This type of problem is next to impossible to guess what might be wrong without having the same configuration in front of me, there are too many things that might affect things in the mix. I haven't use Equalizer myself, I'd guess lots of other OSG users won't have either so you'll likely be using a combination of software that few if any other users have tested before. The best thing you can do is simplify the set up so you have something that works reliably then adding the extra layers of complexity and see what things break. Robert.

I use OpenSceneGraph 3.2.1, osgEarth 2.6 and Equalizer (parallel rendering framework). When I load a sample osgEarth file, I should have a sky and the earth. But I only get one of these, depending on how I set the depth buffer and culling options. I can for example set _camera-setComputeNearFarMode(osg::Camera::DO_NOT_COMPUTE_NEAR_FAR); on the osg camera, then I can get the earth model when I enable the logarithmic buffer from osgEarth with osgEarth::Util::LogarithmicDepthBuffer logDepth; logDepth.install(_camera); When i don't enable this log buffer, I get the sky, a simple sky model from osgEarth, but it flickers (black and the sky), and it shows when I use the mouse to move around. (osgViewer) When I don't set the DO_NOT_COMPUTE_NEAR_FAR, I always get a black screen (black because I disabled GL_COLOR_BUFFER_BIT, otherwise would be the osg blue). I also tried to set near far planes to 0.1, 100 or 0.1, 10, but also with no result. I know I could ask this also in osgEarth forums, but I think it's something I have to set on the osg camera, view or somwhere there, as it is more related to OSG and Equalizer. What could I do to resolve this? And on what all is it depending? Buffers, Culling, Frustum etc?

Re: [osg-users] Android OSG crashed in libcurl of multi-thread
Hi Xua Qingran,
The line 604 in ReaderWriterCURL.cpp is:
osg::ref_ptrOptions local_opt = options ?
static_castOptions*(options-clone(osg::CopyOp::SHALLOW_COPY)) :
new Options; // Line 604
This should be thread safe as lone as the options object isn't being
deleted or modified in a separate thread. As an experiment You could try
taking a local ref_ptr to the options object being passed into the
readFiled() method.
Robert.

Hi,
I am developing a new app based on OSG 3.2.1.
For better download speed, I used a multi-threaded by following code in
JNI:
==
void OsgMainApp::loadModels() {
if (_vModelsToLoad.size() == 0)
return;
osg::notify(osg::ALWAYS) There are _vModelsToLoad.size()
models to load std::endl;
_vTileInfoList.clear();
downloadCacheXMl();
_vTileInfoList = loadDataFromCacheXML();
osgViewer::Viewer::Windows windows;
_viewer-getWindows(windows);
for (osgViewer::Viewer::Windows::iterator itr = windows.begin();
itr != windows.end(); ++itr) {
(*itr)-getState()-setUseModelViewAndProjectionUniforms(true);
(*itr)-getState()-setUseVertexAttributeAliasing(true);
}
_manipulator-getNode();
_viewer-home();
_viewer-getDatabasePager()-clear();
_viewer-getDatabasePager()-registerPagedLODs(_root.get());
_viewer-getDatabasePager()-setUpThreads(3, 2);
_viewer-getDatabasePager()-setTargetMaximumNumberOfPageLOD(2);
_viewer-getDatabasePager()-setUnrefImageDataAfterApplyPolicy(true,
true);
=
I set the _viewer-getDatabasePager()-setUpThreads(3, 2); , but it
often crashed.
However if I set _viewer-getDatabasePager()-setUpThreads(3, 2);, it is
running smoothly.
Here is the crash call stack:

Hi Sergey, Thanks you very much. It's working great with the code you shared. For now, I do not need the transparent clicks, but thanks for the heads up.

Re: [osg-users] is osgEphemeris incompatible with osgShadow?
Hi, Sounds like the SkyDome is in your shadow scene. This simplest way around this is make the ephemeris a sibling to the shadow scene. Thank you!

Re: [osg-users] Issue with StateSet::setUpdateCallback and Drawable
Hi, I didn't get a response to the above questions, so I'm hoping it was just missed due to my post awaiting moderation. It seems like the Drawable StateSet problem is one a lot of people would run into, but I've not found any other mention of it, so possibly I'm just missing something or doing something the wrong way. Anyone able to shed some light on my questions please?
