[osg-users] OSG for android cube texture problem
Hello everyone：I got a cube texture problem in my program base on ES2.0. The
texture is black, does anyone know what is the problem.Here is my shader code:
*Vertex shader *
varying vec3 Normal;
varying vec3 EyeDir;
uniform samplerCube cubeMap;
void main()
{
gl_Position = gl_ModelViewProjectionMatrix*gl_Vertex;
Normal = gl_NormalMatrix * gl_Normal;
EyeDir = vec3(gl_ModelViewMatrix * gl_Vertex);
}
*Fragment shader *
varying vec3 Normal;
varying vec3 EyeDir;
uniform samplerCube cubeMap;
void main(void)
{
vec3 reflectedDirection = normalize(reflect(EyeDir, normalize(Normal)));
reflectedDirection.y = -reflectedDirection.y;
vec4 fragColor = textureCube(cubeMap, reflectedDirection);
gl_FragColor = fragColor;
}
Here is my osg code:
void CSkyBox::setSkyBoxRadius(osg::Vec3 centre, double r)
{
m_centre=centre;
m_r=r;
}
osg::TextureCubeMap* CSkyBox::readCubeMap(osg::Image* imagePosX, osg::Image*

[osg-users] [osgPlugins] PositionAttitudeTransforms ignored when exporting
Hi, I just compiled OSG 3.2.0 with fbx plugin support. When exporting my scene in FBX or 3DS formats, some objects are not correctly placed. This does not happen when exporting to .osg or .ive. Looking further on it, I realized that those objects not located properly were children of PositionAttitudeTransfroms. Replacing PositinoAttitudeTransforms for MatrixTransforms results in correct FBX and 3DS models. I had never tried this before since I have always used native formats, so I'm sorry if this is a known issue that I missed before. Thank you!

Re: [osg-users] [osgPlugins] PositionAttitudeTransforms ignored when exporting
Hi Joseph, I'm not famaliar with the DBX and 3DS formats as I'm not the author of these plugins but I would say in general that 3rd party formats like these will only be able to map a small subset of OSG functionality, and in some case there may be no clear path to implementing it. In the case of PositionAttitudeTransforms the only thing that might be possible would be to convert to a MatrixTransform, potentially this could be done by the exporter, but then what do you do for AutoTransform, Billboards, PagedLODs etc. etc. There is huge parts of the OSG that will be only be supportable by the native formats.

Re: [osg-users] [osgPlugins] PositionAttitudeTransforms ignored when exporting
Thanks for the answer Robert. That was pretty much my guess, in fact I am customizating my scene graph when it has to be exported (replacing LOD, etc.). I just thought PositionAttitudeTransform was of too common use to be left out. In order to minimize the impact on my codebase, I'll try to replace osg::PAT with osg::MatrixTransform through a nodeVisitor, see if that works. Thanks a lot.

[osg-users] Inconsistency detected by ld.so: dl-close.c
Hello,
I have been investigating a crash on shutdown that I suspect is
related to osg or osgEarth singletons. As I was paring down the
application, the crash changed to the following message:
Inconsistency detected by ld.so: dl-close.c: 759: _dl_close: Assertion
`map->l_init_called' failed!
Here is my source code, .earth file, and g++ invocation:
=
#include
int main()
{
osgDB::readNodeFile("test.earth");
return 0;
}
=
=
g++ -pthread -g
/home/cstankevitz/Work/2012-06-01_uavlib/uavlib/Utils/SynVidTest/main.cpp
-losgViewer -losg && ./a.out
=
Can someone tell me why I am getting this error?
Thank you,
Chris

[osg-users] osgDB::Registry::instance(true) sometimes segfaults
Hello,
The first program does not segfault. The second does segfault:
===
#include
int main()
{
osgDB::Registry::instance(true);
return 0;
}
===
#include
int main()
{
osgDB::readNodeFile("/home/cstankevitz/Work/2013-07-02_osgearth/osgearth/tests/crs.earth");
osgDB::Registry::instance(true);
return 0;
}
===
The stack trace, which I'm sorry to say is missing symbols, shows that
the segfault happens during something like static un-initialization.

[osg-users] Occlusion Query Node Error
Hello and thank you for any help in advance,
I am working with some code that a coworker had created, but is unavailable at
the moment. It deals with Occlusion Query Nodes.
When we were still in OSG version 2.8, my coworker had grabbed a lot of the
methods from the 3.0 version's OcclusionQueryNode.cpp and put them in our code
so that we could use them for our sun. However, now that we have transitioned
to 3.0, the code that was brought in isn't being used anymore, defaulting to
OSG's code.
The issue is, whenever our sun is on screen, we are getting the following error
now: "osgOQ: QG: Invalid RQCB."
This apparenlty happens becaues of this area of code:
Code:
RetrieveQueriesCallback* rqcb = dynamic_cast<
RetrieveQueriesCallback* >( cam->getPostDrawCallback() );
if (!rqcb)
{
OSG_FATAL << "osgOQ: QG: Invalid RQCB." << std::endl;
return;
}
I think it might be that we aren't setting up the nodes correctly, but I
haven't been able to find any examples or documentation related to this error
or how to properly set up occlusion query nodes in OSG.
Any help is appreciated, please let me know if you have any questions regarding
my question.
Zach[/code]
