Re: [osg-users] OSG Render Thread in Qt: Access to scene data from main app thread
Hi Robert,
So if I have a class where I describe the scene content and where I do changes
in real time int update function like this:
Code:
DemoOSGScene.h
/*! Cidetec data osg scene class */
class DemoOSGScene: public OSGScene
{
public:
//! An DemoOSGScene constructor.
/*!
A more elaborate description of the constructor.
*/
DemoOSGScene();
//! An DemoOSGScene destructor.
/*!
A more elaborate description of the destructor.
*/
~DemoOSGScene(void);
/** \fn osgGenerals::OSGGroup* getSceneGroup()
Return the scene group
\return osgGenerals::OSGGroup
*/
osg::Group* getSceneGroup() { return _rootGroup; };
/** \fn void update()
Update scene necesary values
\return
*/
void update();
void initialize();
protected:
float getDistanceBetweenObjs(osg::Vec3 obj1, osg::Vec3 obj2);
osg::MatrixTransform* _mainObject;
std::vectorSceneObject_sceneObjectsContainer;
osg::Vec3 _mainObjectV;
//main object velocity vector
int _dificulLevel;
float _nextObject;
osg::Node* _manzana;
};
and the cpp
Code:
DemoOSGScene::DemoOSGScene()
{
_type = DEMO;
_rootGroup = new osg::Group();
_rootGroup-setDataVariance( osg::Object::DYNAMIC );
//define scene camera positions
LookAtCamera camera0 = {osg::Vec3f(0.0, 0.0,0.0),
osg::Vec3f(0.0,100.0,100.0), osg::Vec3f(0.0,0.0,1.0)};
addCameraPos(camera0);
//lights
_rootGroup-addChild(osgGenerals::createLight(osg::Vec3(50.0,200.0,200.0),
osg::Vec4(0.9,0.9,0.9,1.0)));
//load scene models
...
_dificulLevel = 1;
_simulTime = 0.0;
}
DemoOSGScene::~DemoOSGScene(void)
{
}
void DemoOSGScene::initialize()
{
_nextObject = 3.0;
_mainObjectV.set(0.0,0.0,0.0);
_sessionScore = 0.0;
//clean object container
for(int i=0;i_sceneObjectsContainer.size();i++)
{
_rootGroup-removeChild(_sceneObjectsContainer[i].node);
_sceneObjectsContainer.erase(_sceneObjectsContainer.begin()+i);
i--;
}
_mainObject-setMatrix(osg::Matrix::translate(osg::Vec3(mainObjectInitPos[0],mainObjectInitPos[1],mainObjectInitPos[2])));
}
void DemoOSGScene::update()
{
float delta = _simulTime - preSimulTime;
//update objects position
{
...
}
//verify scene object collisions
{
...
}
//create or delete objects
{
...
}
preSimulTime = _simulTime;
}
So in update function I need access to _rootGroup, _sceneObjectsContainer...
I have found this solution:
Code:
class UpdateRootCallback : public osg::Drawable::UpdateCallback
{
public:
virtual void update( osg::NodeVisitor* nv,
osg::Drawable* drawable )
{
...
}
};
_rootGroup-setDataVariance( osg::Object::DYNAMIC );
_rootGroup-setUpdateCallback( new UpdateRootCallback );
But I need to pass my objects pointers from DemoOSGScene... and I don't know
how to put thread access control for the objects...
Is this the best solution?
Thank you!
Cheers,
Aitor

Re: [osg-users] delete scene osg
Hi Lucie Hi, I want to delete a complete scene. I use root-removeChildren(0,root-getNumChildren()); Does it destroys the objects in the scene? Yes and no. First of all it does exactly what the name says. It removes the children from the group. If you don't reference the nodes below that scene anymore(via osg::ref_ptr), they get destroyed (i.e. if their reference count is zero) A simpler approach is to do: root = new osg::Group(), which will also detach all children and is less pain ;-) As you are speaking of the scene, you probably should consider simply setting the viewers scenedata to an empty group: viewer.setSceneData(new osg::Group()); cheers Sebastian Thank you!

[osg-users] attribute from osg to vertex
Hi,
i'm finding a lot of difficult to solve this issue: pass uniform and attribute
parameters from osg application to shader.
In particular, referred to attribute (or in) parameter in vertex program :
Code:
#version 150
attribute vec3 Vertex;
attribute vec2 Uv;
uniform mat4 osg_ProjectionMatrix;
uniform mat4 ViewMatrix;
uniform mat4 osg_ViewMatrixInverse;
uniform vec3 ModelScale;
How can i pass these data from my osg application?
Currently, in my osg applycation i use :
Code:
mProgram-addBindAttribLocation(Vertex,0);
mProgram-addBindAttribLocation(Uv,8);
Is it correct?
I looked at an example on OpenSceneGraph 3 cookbook chapter 6, Using the
bump tecnique where to pass these attributes :
Code:
attribute vec3 tangent;
attribute vec3 binormal;
The authors (Rui Wang, Xuelei Qian) use a ComputeTangentVisitor nodevisitor
class to compute tangent and binormal for each vertex:
Code:
class ComputeTangentVisitor : public osg::NodeVisitor
{
public:
void apply( osg::Node node ) { traverse(node); }
void apply( osg::Geode node )
{
for ( unsigned int i=0; inode.getNumDrawables(); ++i )
{
osg::Geometry* geom =
dynamic_castosg::Geometry*( node.getDrawable(i) );
if ( geom ) generateTangentArray( geom );
//setGeometryVertexArray(geom);
}
traverse( node );
}
void generateTangentArray( osg::Geometry* geom )
{
osg::ref_ptrosgUtil::TangentSpaceGenerator tsg = new
osgUtil::TangentSpaceGenerator;
tsg-generate( geom );
geom-setVertexAttribArray( 6, tsg-getTangentArray() );
geom-setVertexAttribBinding( 6,
osg::Geometry::BIND_PER_VERTEX );
geom-setVertexAttribArray( 7, tsg-getBinormalArray()
);
geom-setVertexAttribBinding( 7,
osg::Geometry::BIND_PER_VERTEX );
}
};
and bind them with the following code :
Code:
ComputeTangentVisitor ctv;
ctv.setTraversalMode( osg::NodeVisitor::TRAVERSE_ALL_CHILDREN );
mModel-accept( ctv );
mProgram-addBindAttribLocation(tangent,6);
mProgram-addBindAttribLocation(binormal,7);
But, in my case vertex are already exist. So i suppose to use only :
mProgram-addBindAttribLocation(Vertex,0);
And what about the Uv parameter? The texture i have to pass to fragment, is a
RTT Camera image, on which i would like to apply some effects.
How can i pass these texture coordinates to shader?
About the uniform parameters, is there a way to pass the ViewMatrix?
I used myCamera-getViewMatrix() in my osgapplication, and i set uniform to
this value inside a callback:
Code:
osg::ref_ptrosg::Uniform viewUniformParam = new osg::Uniform(ViewMatrix,
osg::Matrixf());
viewUniformParam-setUpdateCallback( new
ViewMatrixCallback(mApplicationCamera.get()) );
with :
Code:
class ViewMatrixCallback : public osg::Uniform::Callback
{
public:
ViewMatrixCallback(osg::Camera* appcamera):
osg::Uniform::Callback()
{
mApplicationCamera=appcamera;
};
virtual void operator()( osg::Uniform* uniform,
osg::NodeVisitor* nv )
{
osg::Matrix
vmFromCamera=mApplicationCamera-getViewMatrix();
uniform-set( vmFromCamera );
}
protected:
osg::ref_ptrosg::Camera mApplicationCamera;
};
But i get no results.
Could you give me some suggestions?
Thank you!
Cheers,
Andrea

I suggested this and they confirm it is on. There doesn't seem to be a lot of troubleshooting opportunities.
