[osg-users] memory issue about x-windows in Linux
Hi, I know it is not be an osg problem. Just want to know anyone here may met the same problem. We use reahat linux 6.5 to run our osg app .The desktop is kde4.3.4. . After 7 to 20 days,we found the X-windows Process （X) suddenly took all of system's memory ,and force linux to kill the process itself ,which result to force the redhat back to it's login windows. I have observe both the osg and X problem every single day,it seems every stable ,not any trace of memory leak problem.Then just one short moment,the X process suddenly eats up all system memory . My question is what the link with osg and x-windows？Is it because our app has some memory leak problem to make the X process eat up too many memory ? Or just the X process cause the problem only due to itself? ... Thank you!

[osg-users] How to disable Antialiasing of an osg::Text
Hi,
In linux we are using osg::Text to display some chinese characters.Then
we find the osg::Text looks a little blur when the size of characters is
small.Or,the Black characters seems a little gray when the character size is
small.I have setFontSolution(128,128),it not help.
Then I fond our old app which using QT to draw text,and with the same
font,QT text looks better than osg::Text.
I fond QT use QPaint to loading font and drawing text ,and It can enable or
disable Antialiasing of text like below.
Code:
class Q_GUI_EXPORT QPainter
{
Q_DECLARE_PRIVATE(QPainter)
Q_GADGET
Q_FLAGS(RenderHint RenderHints)
public:
enum RenderHint {
Antialiasing = 0x01,
TextAntialiasing = 0x02,
SmoothPixmapTransform = 0x04,
HighQualityAntialiasing = 0x08,
NonCosmeticDefaultPen = 0x10
};
So my question is ,does osg can enable or disable Antialiasing to an
osg::Text?
...
Thank you!
Cheers,
Lv

[osg-users] a linux dialog starting to blur while draging towards to an OSG QT widgets
Hi, we have integrated an osgViewerQT window to a QT based app. There are four subWindows in our app,one is an osgViewerQT widget,the others are normal QT widgets. We forced the osgViewerQT viewer running under a slow frames,about 10FPS. Then we drag any other linux dialog to the osgViewerQT widget,the linux dialog becomes blur.If we drag the linux dialog to the other three QT widgets,it dose not blur. it seems the slower the osgViewerQT widget running ,the much it blur。 We do this experiment because we have ran the osgViewerQT window with a complex scene.It is very hard to maintain the frames when a lot things are running.So we do not want the performance of an osg scene influence other linux dialogs's updating. A 10FPS osg scence is acceptable,but a blur dialog means bad User Experience:). So any advice?Is it something about double buffer setting? ... Thank you!

[osg-users] performance of QT GUI when integrated with OSG
Hi, I have used class ViewerWidget(: public QWidget, public osgViewer::CompositeViewer) to integrate OSG into a QT application. Like this: viewer3DWindow = new ViewerWidget; QMdiSubWindow *tmpsubwin_3D = new QMdiSubWindow ; tmpsubwin_3D->setWidget(viewer3DWindow); And there are other QT GUIs like QT::Dialog,QT::LineEdit etc,they are in the same application but in different QMdiSubWindow. When our 3D widget (osg widget) has a lot of thing to render,the frame is down to 10 fps or even lower.It is totally acceptable for the 3D widget. However,the GUI widget seems also have low performance as the 3D widget.For example,when we tap some words to a QT::LineEdit,it take a long time to react our input. When 3D widget's frame back to normal,the QT GUI widget's performance is back to normal too. So it looks like the 3D OSG widget and QT GUI widget share the same graphic resource .When cpu or gpu usage is high,the 3D OSG widget try it best to keep performance ,while the QT GUI widget dose not have enough resource to react. We use linux.Any advice? ... Thank you!

Re: [osg-users] how to set width and Stipple of a osgText::BoundingBox?
Thx!Robert! The situation is,we have modified the text.cpp to create some other styles rather than boundingbox. Like a BoundingLine,one end to one of the corner of a BoundingBox,the other end linked to a osg::Node. So if a text have a BoundingLine and a BoundingBox,I just want draw the BoundingBox as normal,but draw the BoundingLine with LineStipple .So I think one osg::StateSet may not solve this problem. I am not quiet familiar with the openGL programming since I use osg at first.I search the web found people use this code to set Linewidth and Stipple glLineWidth (2.0); glLineStipple (1, 0x0F0F); And I look into text.cpp,found lots of code like use openGL directly,such as : //glClear(GL_STENCIL_BUFFER_BIT); // enable stencil buffer glEnable(GL_STENCIL_TEST); // write a one to the stencil buffer everywhere we are about to draw glStencilFunc(GL_ALWAYS, 1, 1); // write only to the stencil buffer if we pass the depth test glStencilOp(GL_KEEP, GL_KEEP, GL_REPLACE); // Disable writing to the color buffer so we only write to the stencil // buffer and the depth buffer glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE); // make sure the depth buffer is enabled //glEnable(GL_DEPTH_TEST); //glDepthMask(GL_TRUE); //glDepthFunc(GL_LESS); // Arrrgh! Why does the code only seem to work correctly if I call this? glDepthMask(GL_FALSE); So I think use the openGL code to draw different style may be the qucik way. ... Thank you!

[osg-users] how to set width and Stipple of a osgText::BoundingBox?
Hi,
I want to modify text.cpp so can set osgText::BoundingBox's width and line

Here is how osg draw BOUNDINGBOX in text.cpp:
if (_drawMode & BOUNDINGBOX)
{
if (_textBB.valid())
{
state.applyTextureMode(0,GL_TEXTURE_2D,osg::StateAttribute::OFF);
const osg::Matrix& matrix = _autoTransformCache[contextID]._matrix;

osg::Vec3
c10(osg::Vec3(_textBB.xMax(),_textBB.yMin(),_textBB.zMin())*matrix);
osg::Vec3
c11(osg::Vec3(_textBB.xMax(),_textBB.yMax(),_textBB.zMin())*matrix);
osg::Vec3
c01(osg::Vec3(_textBB.xMin(),_textBB.yMax(),_textBB.zMin())*matrix);
gl.Color4f(colorMultiplier.r()*_textBBColor.r(),colorMultiplier.g()*_textBBColor.g(),colorMultiplier.b()*_textBBColor.b(),colorMultiplier.a()*_textBBColor.a());
gl.Begin(GL_LINE_LOOP);
gl.Vertex3fv(c00.ptr());
gl.Vertex3fv(c10.ptr());
gl.Vertex3fv(c11.ptr());
gl.Vertex3fv(c01.ptr());
gl.End();
}
}
I have added this two line before gl.Begin(GL_LINE_LOOP):
glLineWidth (2.0);
glLineStipple (1, 0x0F0F);
It seems not work,need help!

[osg-users] performance of a fbx 3D model
Hi, ... I just buy some fbx 3D model with some animation,each 3D model have one main part .fbx file and some separate animation .fbx file. main part .fbx dose not has animation effect if not loading other animation .fbx file . The problem is,when loaded a main part .fbx with osgviewer ,I found the update frame is extremely higher than a normal 3D model which without animation.Like pitcure below: [img]http://bbs.osgchina.org/forum.php?mod=attachment&aid=NjE2NHw4OTNhYTA4M3wxNDI1Mz [/img] the update frame is 6.8 . If I convert main part .fbx to main part .ive ,the update frame is 0.0~0.01 more than 100 main part .fbx will drop performance of our app significantly. I think a fbx file may attach some bone updatecallback even it does not run a animation , so the question is ,may i close the updatecallback of a fbx file when i do not need the animation ,or other way just improve the performance of a fbx 3D model?

Hi,
I have failed to draw a line between a osg::Text and a 3D model,like image

So far,I have managed modify osg::Text to draw a linking line ,like draw a

One end of the line is linked to the text,but I do not know how to link another
end to a moving 3D model.
I figure must do something to compute the world matrix of the 3D model
,then convert it to the local matrix of the osg::Text,then draw another end of
the line to the local matrix.
here is what I have done,and the result is not good.
1. a class to get the text Wolrd To Local
class GetWolrdToLocalVisitor:public osg::NodeVisitor

[osg-users] memory releasing problem by addchild and removechild
Hi, ... I have read some posts about memory releasing problem by addchild and removechild. Here is my situation ,we developed osg app by qt in win7, we use class ViewerWidget to adding our viewer as a qt widget. We did a test to simply adding 5 osg::Node to a osg::Group then removing all nodes and the group.After first adding ,it increase about 4000K memory ,I think it is the proper storage of 5 osg::Node,then by the first removing,it only decrease 400K。Then by another 5 adding ,it only increase 400K instead 4000K,if we removing all nodes again ,it still decrease 400K. No matter how many time we tried to adding or remove nodes ,if we keep the max test node to 5,It always hold the 4000K memory even we remove all nodes. It looks like osg still hold the first 5 osg::Node as a Cache ，not releasing it immediately。 But I must admit ,it do releasing the memory properly in osgViewer or other osg examples by the same test! We use win7 ,osg2.9.16 ,osg3.2.0,we observe memory change by windows resource management. Need help! Thank you!

[osg-users] how to zoom in and out a earth model with two fingers when using a Multi-touch screen
Hi, It is actually a osgEarth problem.but I have lost track of it in osgEarth forum,and someone there said it is something about GraphicsWindowQT and osg 3.1.3,so I think I may get help here. By osg 3.2.0 ,osgEarth 2.5, qt 4 ,win 7,I can zoom in and out earth with two fingers when running osgEarth_viewer or osgEarth_manip example,but when ingreated osgEarth to qt,like the osgEarth_qt_package example,the zoom funcion fails. In osgEarth forum ,Mr jasonbeverageReply said : " If you're using QT I think you need some patches to the GraphicsWindowQT to get it to work. I've attached a patch GraphicsWindowQt. It's been modified against osg 3.1.3 and not the trunk osg so I haven't submitted it to Robert yet. You should be able to see what I did to patch it and apply it locally." then I lost the track,what should I do? ThX! how to zoom in and out with two fingers when using a Multi-touch screen Thank you!

[osg-users] the original QT events seems conflicted with osg's event handle.
Hi,
I used "class ViewerWidget : public QWidget, public
osgViewer::CompositeViewer" to integrate osg with qt.
Then I used osg's event handle to handle some mouse push or release event
,it works fine.
But there are some other QWidgets may pass event to my 3D ViewerWidget .
For example ,I drag some symbols from one qt dialog to my 3D ViewerWidget
,which should activate the 3D ViewerWidget's drop event.
Since I do not find osg has the drop event,so I define and realize one as
follow in ViewerWidget .h
virtual void dropEvent( QDropEvent* event )
{
printf("drop");
}
It is not functional.
The I try other QtEvents like mousePushEvent or mouseMoveEvent,none
works.It seems the osg or osgEarth's event handle may block the original QT
events.
Need help!
Thx!
Thank you!
Cheers,
Lv

[osg-users] Is it necessary to re-compile osg when graphics card been changed?
Hi, I have changed my graphics card from GTX260 to Quadro FX 370 . Recently I find my app sometimes crashed as below: in free() from /lib/libc.so.6 libnvidia-glcore.so.260.19.44 which seems untraceable. Then I find a mistake ,I still use the GTX260 driver after changing to the FX 370 . However ,the linux system seemd recognise the FX 370 without problem. Sure,It is easy to reinstall the correct driver,but since our app is already deployed to customer.I may trade this problem carefully. So my question is: Is a incorrect driver may cause the libnvidia-glcore.so. problem? and If I change the driver ,Is it necessary to re-compile osg under Linux? Thank you!

Hi, My osg2.9.11 app is working under QT/Linux.Occasionally it suffers a dead lock as follows: #0 in _kernel_vsyscall() #1 in pthread_cond_wait_@@GLIBC_2.3.2 from/lib/libpthread #2 in Openthreads::Condition::wait from libOpenThreads #3 in osgDB::DatabasePager::DatabaseThread::run from libosgDB #4 in OpenThreads::ThreadPrivateActions::StartThread from libOpenThreads #5 in ?? from/usr/lib/libGL.so The only function I use from libosgDB is just loading a osgDEM terrain file,nothing else.So I think maybe DatabasePager rendering terrian file conflict about something. Another clue is my osg thread is integrated with other qt thread,just use the AdpateWidget.cpp example.Previously,I found DatabasePager rendering confilic with some QT signal.It presents just loading and runing a terrain file may affect some other thread's share memory and leading some unusual crash.I solve this problem by blocking these QT signals before every fram() function.

[osg-users] osg::Lod and osgText::FadeText
Hi, I have used osgText::FadeText for displaying some GIS lables. I also want to use osg::Lod for displaying the FadeText in a certain distance away from viewer. osg:OD* lod = new osg:od; lod->setRangeMode(osg:OD:ISTANCE_FROM_EYE_POINT); lod->addChild(textGeod,0,3000*1000); //textGeod already attacting a FadeText which set fixed size to the screen. root->addChild(lod.get()); I can not see the FadeText ,then I set lod->addChild(textGeod,0,1*1000); the FadeText is visible,but it is meaningless.

[osg-users] osgText:FadeText attaching small object seems invisible initiatly
Hi, ... I have used osgText:FadeText attaching a model for displaying it's text information.I set the osgText:FadeText always It is OK in most case.Then I found if the model's size is small enough and the distance from viewer is too long(like 3000KM),the osgText:FadeText is not visible when the model been loaded the first time. Then I zoom the viewer in,the osgText:FadeText is visible in certain distance,if I zoom the viewer out again,the osgText:FadeText is still visible.Then nomatter how far the osgText:FadeText away from the viewer,it is OK like normal. It means when the first time I loaded the model ,the osgText:FadeText may keep invisible and waiting me to find it. It is certainly something about model's size,if it is big enough ,the problem will never happen. Need help! Thank you!

[osg-users] Computing Near and Far problem when viewing large terrain and small object
Hi, My applicaiton use a quiet large terrain model (about 4000KM*4000KM),and when I viewing some very small flying objects(about 20m*20m) above the terrain ,the object seems been culled. I know it is the Near and Far Plane issue,so I setComputeNearFarMode(osg::CullSetting::COMPUTE_NEAR_FAR_USING_PRIMITIVES); setNearFarRation(0.0001); It solves the problem,make the small objects visible. However it causes another problem ,I have also loaded some vector GIS models (such as roads,country boundraies) which made by osgGIS. When I COMPUTE NEAR FAR USING PRIMITIVES,the vector models cause me 50% ~60% CPU usage!When I disabled COMPUTE NEAR FAR USING PRIMITIVES,or hiding the vector models ,it only cost me 10%~15% CPU usage.The vector models is only 3.5mb. Is there a better solution to solve this problem? Thank you!

Thank you !How can I use the local up-vector at that point?
Is that?
Code:
osg::Vec3d m_center;
csn->getEllipsoidModel()->convertLatLongHeightToXYZ(osg::inDegrees(40.0f),osg::inDegrees(120.0f),0.0f,double(m_center.x()),double(m_center.y()),double(m_center.z()));
osg::Vec3d center;
center.set(csn->getEllipsoidModel()->computeLocalUpVector(m_center.x(),m_center.y(),m_center.z()));

[osg-users] [vpb] convertLatLongHeightToXYZ problem with a geocentric coordinate earth
Hi,
I have build a geocentric coordinate earth model using VPB and want to put a
simple model on the suface of the earth.
I use the convertLatLongHeightToXYZ function to convert the
BLH(Lat,Long,Height) of the simple model to XYZ of the
geocentric coordinate system.The result of X and Y seems OK,but the Z
coordinate is always a bit higher above the earth suface(about 5000 m).
Code:
// load the earth model
osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode;
csn->setEllipsoidModel(new osg::EllipsoidModel());
osg::Node* TerrainNode= osgDB::readNodeFile("earth.osga");
csn->addChild(TerrainNode);
//convert the BLH(50,130,0) to XYZ,I set height 0.
osg::Vec3d m_surface;
csn->getEllipsoidModel()->convertLatLongHeightToXYZ(osg:egreesToRadians(50.0f),osg:egreesToRadians(130.0f),0.0f,double(m_surface.x()),double(m_surface.y()),double(m_surface.z()));
//draw a simple yellow line from center of the earth (osg::Vec3(0,0,0)) to the
surface (osg::Vec3d m_surface);
osg::Geode *geode_line = new osg::Geode;
osg::Geometry *geom = new osg::Geometry();
geode_line->addDrawable(geom);
csn->addChild(geode_line);
osg::Vec3Array *v = new osg::Vec3Array();
v->push_back(osg::Vec3(0,0,0));
v->push_back(m_center);
geom->setVertexArray(v);
osg::Vec4Array *vc = new osg::Vec4Array();
vc->push_back(osg::Vec4(1.0f,0.5f,0.0f,1.0f));
geom->setColorArray(vc);
geom->setColorBinding(osg::Geometry::BIND_PER_PRIMITIVE);
geom->addPrimitiveSet(new osg:rawArrays(osg:rimitiveSet:INES,0,2));
As the result ,the end of the yellow line is obviously higher than the
surface.Please tell me where I am wrong,THX!
Thank you!
Cheers,
Lv

Re: [osg-users] High CPU usage problems with multi-monitor(TwinView) using Nvidia card, osg2.8
Hi, Here is my setup: -- Intel Core 2 6420 2.13GHZ -- 3G RAM -- Nvidia GeForce GTX 260 (drivers: 6.14.11.8242 2009-3-9) -- winxp sp2,vs2005 -- osg2.8 In single monitor mode everything is working fine.When I run my application,CPU usage is a constant 10%~15%. But when I use two monitors and set the Nvidia card to "TwinView" mode ,the CPU usage dramatically raise to 50%.It is basically using an entire CPU core since I use a 2 core machine.Then I find the same problem happens when I run any OSG example or any OSG application in TwinView mode!It is OK when I use other multi-monitor mode such as "horizontal pan ". So I think maybe it is something wrong with the OSG2.8 and the "TwinView" mode of Nvidia card? Any one can help me? Thank you!
