Re: [osg-users] IntersectVisitor does not recognize Nodes on different Projection
Hi, OK. Thank you. Got it working now. Changed setProjectionMatrixOrtho2D into setProjectionMatrixOrtho. Next problem that i have is that the Buttons in my SceneGraph consist of several geometries and the Button is a Geode but its not recognized as Geode. Only as several Geometries. I dont know how to solve this. After going through the API i found Geode-setNodeMask. Could this help maybe? Ive no idea what a nodemask is though... Thank you!

Re: [osg-users] IntersectVisitor does not recognize Nodes on different Projection
Hi, Thanks for the tip but i dont see the difference which makes it work and mine not. Ive changed some parts of my code but i in my opinion it should work. Any further help is highly anticipated.

[osg-users] IntersectVisitor does not recognize Nodes on different Projection
Hi, I've got a loaded model which is a child of the root. the second child of the root node is a ortho2d projection, which i use for the GUI. Now i've taken the example osgkeyboardmouse from the osg site and my problem is that it only catches intersections with the loaded model. Not with the Goedes which are at the Ortho2D ProjectionMatrix. double w(.05), h(.05); osgUtil::PolytopeIntersector* picker = new osgUtil::PolytopeIntersector( osgUtil::Intersector::PROJECTION, x-w, y-h, x+w, y+h); osgUtil::IntersectionVisitor iv(picker); viewer-getCamera()-accept(iv); this is how i configured the Visitor. I've tried to change the Intersector into a osg::Intersector::WINDOW. ut then absolutely nothing happens anymore. Thanks in advance.

[osg-users] Functioncall error
Hi,
Here's the code first:
class TGTextNode : public osg::Geode
{
public:
TGTextNode(std::string T_Text, int T_Size, int T_Res, int T_PosX,
int T_PosY, int T_PosZ);
void addOutline();
};
TGTextNode::TGTextNode(std::string T_Text, int T_Size, int T_Res, int T_PosX,
int T_PosY, int T_PosZ)
{
osg::ref_ptrosgText::Text textobj = new osgText::Text;
textobj-setAlignment(osgText::Text::CENTER_CENTER);
textobj-setCharacterSize(T_Size);
textobj-setFont(bewilder.ttf);
textobj-setFontResolution(T_Res, T_Res);
textobj-setPosition(osg::Vec3(T_PosX, T_PosY, T_PosZ));
textobj-setColor(osg::Vec4(100, 50, 0, 1));
textobj-setAxisAlignment(osgText::Text::SCREEN);
textobj-setText(T_Text);
//textobj-setBackdropType(osgText::Text::OUTLINE);
//textobj-setBackdropColor(osg::Vec4(1,.1,.1,1));
textobj-setDataVariance(osg::Object::DYNAMIC);
this-addDrawable(textobj.get());
}
void TGTextNode::addOutline()
{
textobj-setBackdropType(osgText::Text::OUTLINE);
textobj-setBackdropColor(osg::Vec4(1,.1,.1,1));
}
The point is that textobj in Function addOutline is an unknown member for the
compiler. My first thought was that i need an copyconstructor. I tried to
implement one but with no success. Can you help me. I know that this is maybe a
bit noobish, but im really stuck here.
Thank you!
Cheers,
Thorsten

Re: [osg-users] std::vector instances from osg::geode derived class error
Hi,
Thanks for your help. I'm a bit further now and everything works fine. That is
what i did
std::vectorosg::ref_ptrTGWidgetElement ElementUpper;
std::vectorosg::ref_ptrTGWidgetElement ElementLower;
for(i=count_width; i0; i--, elementindex_w++)
{
ElementLower.push_back(new TGWidgetElement(size,size,posXLL,
posY, WidgElementSideLower.png));
ElementUpper.push_back(new TGWidgetElement(size,size,posXLL,
posYUR, WidgElementSideUpper.png));
posXLL += size;
ElementUpper[elementindex_w].get()-setDataVariance(osg::Object::DYNAMIC);
ElementLower[elementindex_w].get()-setDataVariance(osg::Object::DYNAMIC);
this-addChild(ElementUpper[elementindex_w].get());
this-addChild(ElementLower[elementindex_w].get());
}
actually im working on the handler.
This problem is solved.
Thank you!
Cheers,
Thorsten

[osg-users] std::vector instances from osg::geode derived class error
Hi,
I'm trying to instanciate TGWidgetElement with a std::vector, which derives
from osg::geode with a std::vector but it gives following errors.

The Code:

int posY = 370;
std::vectorTGWidgetElement ElementLower;
for(int i=count_width; i0; i--)
{
ElementLower.push_back(TGWidgetElement(posX, posY,

posX += 15;
posY += 15;
//this-addChild(ElementLower[count_width]);
}
I'm really stuck here. What am i doing wrong???
Thank you!
