Hi,
please can you help me with this? I have a node globe (from osgEarth). All I
want now is add a new model (for example helicopter) and place it on top of the
surface of the globe and set camera so that it points like from the helicopter
model.....
I have tried MatrixTransfrom, but most probably am not using it right...
Here is what I made until now..(I'm not able to see both nodes together. only
globe, or helicopter...)
Code:
osg::Group* root = new osg::Group();
osg::ref_ptr<osg::Node> globe =
osgDB::readNodeFile("multiple_heightfields.earth");
osg::ref_ptr<osg::Node> heliNode = osgDB::readNodeFile("CH-146 Griffon.flt");
osg::MatrixTransform* mNavTrans = new osg::MatrixTransform();
root->addChild(globe.get());
root->addChild(mNavTrans);
double s = 100.0;
osg::Quat rotation;
osg::MatrixTransform* mModelTrans = new osg::MatrixTransform();
mModelTrans->preMult(osg::Matrix::rotate(-90.0f, 1.0f, 0.0f, 40.0f));
mModelTrans->setMatrix(osg::Matrixd::scale(s,s,s));// I have tried only with
scale but it didn't work
mModelTrans->addChild(heliNode.get());
mNavTrans->addChild(mModelTrans);
osgUtil::Optimizer optimizer;
optimizer.optimize(root);
Thank you!
Cheers,
miroslav[code]
