[osg-users] osg crashes when remove child
Hi,
I embed osg in wpf application with this code :
http://www.openscenegraph.org/projects/osg/wiki/Support/FAQ#HowdoIembedanOSGviewerina.NETcontrol
I load a scene of vrml files.
osg::Group* root = new osgGroup();
for(int i = 0; i listFichiers.size(); i++){
osg::Node* node = osgDB::readNodeFile(listFichiers[i]);
node-setDataVariance(osg::Object::DYNAMIC);
root-addChild(node);
}
When I want to remove scene to load another scene
(root-removeChildren(0,root-getNumChildren())), osg crashes with error :
Debug assertion failed :
Expression:(this-_Has_container(),0)
...
The call stack is stop on this :

Re: [osg-users] convertLatLongHeightToXYZ
Hi, Thank you everyone for your replies. In fact, I made a mistake because I built my terrain with VPB with the option --geocentric so my terrain is geocentric. I didn't remember anymore. In fact, I rotate the terrain and that's why it seem flat. But your answers helped me a lot because I might build flat terrain. Thank you!

Hi, Can you explain me a little the function osg::EllipsoidModel::convertXYZToLatLongHeight? I don't understand why x and y are calculated based on height.

Re: [osg-users] convertLatLongHeightToXYZ
Hi, I understood that the XYZ are in Earth Center Earth Fixed coordinates. So is it normal that X,Y are calculated based on height? In fact, I put a latitude, longitude and height on a model, I use osg::EllipsoidModel::convertLatLongHeightToXYZ to obtain the position x,y,z and I transform my point with the MatrixTransforms applied on the terrain model and I place my model with the transformed point.

[osg-users] Intersection with a ray
Hi,
I use osgUtil::LineSegmentIntersector to obtain the intersections between a
mouse or a ray starting from a wand and a terrain generated with
VirtualPlanetBuilder and to display the latitude, longitude and height of the
intersection point.
When I use the LineSegmentIntersector with the mouse and I use the camera which
accept the IntersectionVisitor, the values of latitude, longitude and height
are correct.
Here is my code :
osg::ref_ptr osgUtil::LineSegmentIntersector picker = new
osgUtil::LineSegmentIntersector(osgUtil::Intersector::WINDOW, x, y);
osgUtil::IntersectionVisitor iv(picker.get());
view-getCamera()-accept(iv);
if (picker-containsIntersections())
{
intersections = picker-getIntersections();
for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr =
intersections.begin();
hitr != intersections.end();
++hitr)
{
osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode;
csn-setEllipsoidModel(new osg::EllipsoidModel());
csn-addChild(group);
point = hitr-getWorldIntersectPoint();
double latitude;
double longitude;
double height;
csn-getEllipsoidModel()-convertXYZToLatLongHeight(point.x(),point.y(),point.z(),latitude,longitude,height);
latitude = osg::RadiansToDegrees(latitude);
longitude = osg::RadiansToDegrees(longitude);
std::cout lat,long,height( latitude ,
longitude , height ) std::endl;
}
}
But, my goal is to obtain the intersections of the terrain with a ray starting
from a wand. I use here LineSegmentIntersector with the start point of a wand
and the end point and I use the rootNode which accept the IntersectionVisitor.
But in this case, the values of latitude, longitude and height are false.
Here is my code :
osg::Vec3 wandp1;
osg::Vec3 wandp2;
osg::ref_ptr osgUtil::LineSegmentIntersector picker = new
osgUtil::LineSegmentIntersector(wandp1,wandp2);
osgUtil::LineSegmentIntersector::Intersections intersections;
osgUtil::IntersectionVisitor iv(line.get());
rootNode-accept(iv);
if(picker-containsIntersections()){
//same code as before
}
In red are the differences between the two methods.
I don't understand what is the problem.
Can you help me, please?
Thank you!
Cheers,
lucie

[osg-users] Calculate latitude, longitude, height with intersection point
Hi,
I want to obtain the latitude, longitude and height when I click with the
mouse. Here is my code :
osgGA::GUIEventAdapter ea;
osgUtil::LineSegmentIntersector::Intersections intersections;
std::string gdlist=;
float x = ea.getX();
float y = ea.getY();
osg::ref_ptr osgUtil::LineSegmentIntersector picker = new

osgUtil::IntersectionVisitor iv(picker.get());
view-getCamera()-accept(iv);
if (picker-containsIntersections())
{
intersections = picker-getIntersections();
for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr =
intersections.begin();
hitr != intersections.end();
++hitr)
{
std::ostringstream os;
if (!hitr-nodePath.empty()
!(hitr-nodePath.back()-getName().empty()))
{
// the geodes are identified by name.
osObject
\hitr-nodePath.back()-getName()\std::endl;
}
else if (hitr-drawable.valid())
{
osObject
\hitr-drawable-className()\std::endl;
}
osg::CoordinateSystemNode* csn = new osg::CoordinateSystemNode;
csn-setEllipsoidModel(new osg::EllipsoidModel());
csn-addChild(TerrainNode);
oslocal coords vertex(
hitr-getLocalIntersectPoint())std::endl;
osworld coords vertex(
hitr-getWorldIntersectPoint())std::endl;
osg::Vec3 point = hitr-getWorldIntersectPoint();
double latitude;
double longitude;
double height;
csn-getEllipsoidModel()-convertXYZToLatLongHeight(point.x(),point.y(),point.z(),latitude,longitude,height);
latitude = osg::RadiansToDegrees(latitude);
longitude = osg::RadiansToDegrees(longitude);
oslat,long,height( latitude , longitude
, height ) std::endl;
gdlist += os.str();
}
}
This works well when I don't make a translation or rotation on the terrain.
But when I make a translation for example :
TerrainNode= osgDB::readNodeFile(geo.osg);
osg::ref_ptrosg::Group group = new osg::Group;
osg::ref_ptrosg::MatrixTransform mat = new osg::MatrixTransform;
group-addChild(mat);
mat-addChild(TerrainNode);
osg::Matrix trans;
trans.makeTranslate(osg::Vec3f(1000,5000,1500));
mat-preMult(trans);
the values of latitude, longitude and height are false and it's normal.
I would prefer to use local point hitr-getLocalIntersectPoint(), which does
not change when I make a translation, to calculate the latitude, longitude and
height but I don't how to do this.
Can you help me?
Thank you!
Cheers,
lucie

[osg-users] intersections
Hello,
I use osg:: LineSegment to perform an intersection between a ray starting from
a wand and the objects in my scene. Here is my code:
osg::Vec3 wandpt1;
osg::Vec3 wandpt2;
line = new osg::LineSegment(wandpt1,wandpt2);
osg::BoundingBox modelbox;
modelbox.expandBy(modelTransf-getBound());
if(line-intersect(modelbox)){
std::cout intersection with the cow std::endl;
}
The problem is that detection is not very precise.
Do you know another solution in openscenegraph for this?
Thank you!
