[osg-users] [osgPlugins] FBX Texture not loaded when loading more than 50 different Models
Hi, we encountered another Problem with Textures. If i add more than 50 different Models (500 Polygons each,different Textures) only the first ~30 get their Texture. The other are added correctly, just their Textures are missing. I tried manipulating the Texturepool without succes. How can we fix this Problem? Thank you!

There isn't any way for us to know exactly what the problem with so few details. All we know is that load too many models on a unspecified OS, on an unspecified hardware and drivers and unspecified version of OpenGL and OSG, with a program that we know little about other than it uses the OSG. The process to work out what the problem is would be: Loaded each of the models individually. Do they all work correctly? When you load the models together do you get any OSG or OpenGL errors? How large are the models with imagery? What hardware and OS do you have? What version of the OSG and version of OpenGL are you targeting?

[osg-users] osg::Text setText - changing text during rendering
Hi,
I have problems with changing text during rendering. I am trying to change the
text in the update callback of the text node, but sometimes I get a crash
(operator not incrementable) in the osg::osgText.
Here is what I do in the update callback (Call the updateText() function on a
different object):
Code:
void PiMeasurementGeomCallback::update( osg::NodeVisitor* nv,
osg::Drawable* geom){
if(textDirty){
textDirty = false;
PiMeasurement* mes =
dynamic_castPiMeasurement*(measurementGroup.get());
if(!mes) return;
mes-updateText();
};
};
and here is the updateText() function:
Code:
bool PiMeasurementLine::updateText(){
double length = (_endPoint-_startPoint).length();
length =
vectorAlongVector(PiSolidComponent::getv3(_movePlane),(_endPoint-_startPoint));
if(length/2-(20*ratio) 12*ratio){
textGeom-setAlignment(osgText::TextBase::CENTER_BOTTOM
);
}else{
textGeom-setAlignment(osgText::TextBase::CENTER_CENTER
);
}
char s[20];
sprintf(s,%.2f,length);
osgText::String str = osgText::String(s);
textGeom-setText(str); / if I comment out this, I get
no crash but I have to change the text anyhow
textGeom-setPosition(PiSolidComponent::getv3(_movePlane)*(length/2));
return true;
}
The textGeom is actually the object where the update callback is attached(the
same as in geom parameter of the update function),
What is the correct way to change the text of an osgText::Text geometry?
Thank you!
Cheers,
Peter

Re: [osg-users] osg::Text setText - changing text during rendering
Hi Peter,
If you are getting a crash then it's likely running the viewer
multi-threaded (the default if you are on a multi-core machine) so
that you are updating the text at the same time it's being used in the
draw traversal. The way to resolve this is to do
text-setDataVariance(osg::Object::DYNAMIC); as this tells the draw
traversal that you plan to modify it the next frame is held back until
all the dynamic objects have been dispatched to OpenGL.
Robert.

The moveToThread command must be called with the Qt widget and the Qt graphics thread before makeCurrent is called the first time. What does moveToThread do? Is it a form of release context? Under Windows the GraphicsWindowWin32::releaseContext() is implemented with a wglMakeCurrent(_hdc, NULL) while X11 has glXMakeCurrent( _display, None, NULL ). The release context is used to make sure that a thread no longer retain a context as being current, allowing it to be made current in another thread.

Oh the joy of a windowing toolkit trying to do everything... It rather does seem like a lot of hoops to jump through, and that we'd need to compile the OSG against Qt, not just osgQt to get things to work. Perhaps one way round would be for osgQt to provide it's own OpenThreads integration, or perhaps for osgViewer to allow the osg::GraphicThread threads to be provided in an more user definable way. Where I'd like to get to is have the core OSG usable directly and independently from Qt, and only osgQt and the Qt examples requiring Qt or a specific version of Qt.

Hello Robert and Pjotr. Actually, I was sure that the data variance is set to Dynamic. But now after a closer look I've found out that instead of text-setDataVariance(DYNAMIC); I wrote this-setDataVariance(DYNAMIC); Thanks to you I've found the problem!

Re: [osg-users] Deprecating vertex indices in osg::Geometry
Hi All, After brief foray back to do some client work and merging submissions I have returned to looking at the new cleaned up Geometry and a GeometryDeprecated fallback implementation. Currently I'm doing a experimental build of the OSG with GeometryNew now named Geometry, and the old Geometry renamed GeometryDeprecated. Most of the core OSG classes and plugins have ported across pretty easily, in many cases the code has now become simpler because there osg::Geometry now is also using fast paths and there are no indices to worry about. Sticking points will be the .osg, .ive and new serializers as they are all built around there been indices to read and write. I don't know yet how to tackle this so I'm going to try and get the rest of the OSG built against Geometry/GeometryDeprecated before returning to how to tackle the native OSG file formats. I'll keep you all updated on how things progress. Fingers crossed the bulk of the core OSG work related to these changes will be checked in this week.

[osg-users] Vec{2,3,4}{b,s,i,f,d,ub,us,ui} harmonisation
Hi Robert, Hi All
About Vec{2,3,4]{b,s,i,ub,us,ub}, I think we need to do a code harmonisation
of all this header to provide
- operator + - * / += -= *= /= (value_type)
- operator + - += -= (vec_type)
- operator -() for signed type
- componentMultiply, componentDivide
- swizzle, this meen 256 possible functions for Vec4, 512 possible
functions for xyzw and rgba combinaison
- constructor like in GLSL : Vec4(Vec2, Vec2) or Vec4(float, Vec2, float)
or Vec4(float, Vec3),
- use of template
thoughts ?

Re: [osg-users] Qt5 integration first try
Hi Martin,
in reference to my submission here:
http://forum.openscenegraph.org/viewtopic.php?p=54555#54555
as I said, I simply submitted Vitezslavs patch. I can certainly try to remove
the extra hooks from the osg main classes.
The moveToThread command must be called with the Qt widget and the Qt graphics
thread before makeCurrent is called the first time.
Maybe there is a way to achieve multithreaded rendering in a
non-intrusive way by simply calling both new members (moveToThread and
moveBack) from GraphicsWindowQt itself. We could overload
GraphicsContext::setGraphicsThread and
GraphicsContext::releaseContextImplementation with something like this:
void GraphicsWindowQt::setGraphicsThread(osg::GraphicsThread* gt)
{
if (gt)
{
moveToThread(gt);
}
osgViewer::GraphicsWindow::setGraphicsThread(gt);
}
bool GraphicsWindowQt::releaseContextImplementation()
{
existing stuff here ...
// move context back to main thread
if (_widget-context()-thread() != qApp-thread())
{
moveBack();
}
return result;
}
Of course, setGraphicsThread should be made virtual if not already.
Another thing I just realized: The code will only work when CMake option
BUILD_OPENTHREADS_WITH_QT is set! Otherwise the static_cast in
GraphicsWindowQt::moveToThread will fail.
How can I solve this? For multithreading to work with Qt5 it seems we need the
render threads to be QThreads. Maybe add a flag to OpenThreads/Config and
#ifdef against that?
Flag is ok ... or maybe we could add new api to OT, an api that can
return string like qt, win32, pthreads, sproc, c++11... ,
benign but useful ...

Re: [osg-users] Vec{2,3,4}{b,s,i,f,d,ub,us,ui} harmonisation
Hi, I think this is a really interesting idea. Have a look here : http://glm.g-truc.net/ This library already implements a lot of glsl-like syntax. Before rewriting everything (that's not complex, but a lot of work) maybe we could make osg and glm work together ? Maybe adding to glm headers the needed methods to be compatible with osg code ? or copy-paste some code from glm to osg ? (license is MIT, so I think that's ok) Thank you!
