Re: [osg-users] Using osga archive bigger than 2Go
Hi, I've found the problem : In file osgPlugins\osg\BinaryStreamOperator.h, there is call to seekp / teelp to get current stream position, using int variables, which leads to problems if the stream size exceed 32-bits signed integer maximum limit. I've sent a submission to solve this here : http://forum.openscenegraph.org/viewtopic.php?t=13928 Thank you!

Re: [osg-users] Disable light in shaders?

[osg-users] MergeGeometryVisitor behaviour, is this a bug?
Hello,
we were using the MergeGeometryVisitor for our geometry and lately realized
that it totally ignores the setTargetMaximumNumberOfVertices settingf 1
(or actually every setting).
While trying to comprehend what bool
Optimizer::MergeGeometryVisitor::mergeGeode(osg::Geode geode) is trying to do
I came across this code:
unsigned int numVertices(duplicateList.front()-getVertexArray() ?
duplicateList.front()-getVertexArray()-getNumElements() : 0);
DuplicateList::iterator eachGeom(duplicateList.begin()+1);
// until all geometries have been checked or _targetMaximumNumberOfVertices is
reached
for (;eachGeom!=duplicateList.end(); ++eachGeom)
{
unsigned int numAddVertices((*eachGeom)-getVertexArray() ?
(*eachGeom)-getVertexArray()-getNumElements() : 0);
if (numVertices+numAddVertices_targetMaximumNumberOfVertices)
{
break;
}
else
{
numVertices += numAddVertices;
}
}
// push back if bellow the limit
if (numVertices_targetMaximumNumberOfVertices)
{
if (duplicateList.size()1) needToDoMerge = true;
mergeList.push_back(duplicateList);
mergeListChecked.erase(itr);
}
This piece of code iterates over a given list of duplicates and fetches the
vertex count of the first object. Then it iterates over second to last objects
BUT for the second element it fetches numAddVertices and enters the given
condition:
if (numVertices+numAddVertices_targetMaximumNumberOfVertices)
Our scenario has 3 vertices in first and 3 vertices in second geometry which
result in 3+3 10. So the code directly breaks.
Then it checks again for numVertices targetMaximumNumberOfVertices which is
still true and then PUSHES the entire list into mergeList.
Our example is a flight file consisting of thousands of geodes having only 3
vertcies. The duplicateList has several thousand elements but the code checks
only the first two and then pushes the first two AND the remaining thousands of
geodes into the list to merge exceeding the _targetMaximumNumberOfVertices.
Shouldn't the condition
if (numVertices+numAddVertices_targetMaximumNumberOfVertices)
be
if (numVertices+numAddVertices_targetMaximumNumberOfVertices)
and the mergeList.push_back(duplicateList);
pushing only second to eachGeom range into the list?
Regards,
Sam

[osg-users] Proposal: Migrate to a StackExchange like site?
Hello, due to my long absence here I've realized that OpenSceneGraph has still this more than awful mailing list system from the early 1990. The forum mirror where I basically failed the captcha verification as I was presented with detecting something that looked like a celtic modification of an A (A was wrong :/) is quite dated too. So I thought about asking whether there is an interest to move the support to a modern (probably better) level. I hope many people already know stackoverflow (http://stackoverflow.com/) and the stackexchange team allows to propose a new site by posting it to http://area51.stackexchange.com/ . When enough interest is generated, the site will be public. I mean come on. This mailing list still posts my own password back to me as plaintext and having the ability to participate at other stackexchanges sites with one account looks quite appealing while gaining a much better way of monitoring OpenSceneGraph instead of being either flooded by mails or getting none.

Re: [osg-users] MergeGeometryVisitor behaviour, is this a bug?
Hi Sam,
It looks like a bug to me and your suggested fix looks appropriate.
I've applied this fix to svn/trunk and OSG-3.2 braches.
Thanks,

Re: [osg-users] Shader Problems, AMD is Fine, NVIDIA is not
Hi, seems like it was part of the problem, but not all of it. Intel HD4400 and my AMD Cards still work fine, but the Quadro 600 is missing all light it seems, it s much darker then it shoud be, it seems like not all lights are used. Furthermore, trying to get the shader work on the GTX 660 TI or 670 or something from NVIDIA is still not working, or it's messed up. (No Bingo, but still false light or all white). Furthermore, the CommandLine is giving constantly: warning: detected opengl eror 'invalid enumerant' at after RenderBin:.draw(...) It should maybe maintain, that the working AMDs are running on Windows, while the Quadro 600 runs on Linux. But the non-working GTX ones are runnning windows, too. Does anyone have an idea or an suggestion? Or would at least be so kind to answer me and tell me, that he has no idea? It is kind of depressing, posting questions and never get any answers.
