ok, I understand...
but is there anyway to have a Geometry object from a osg::Node?
I am trying with this lines of code but I have no success because "no geode is
found" is printed.
Code:
osg::Geode *geode = dynamic_cast<osg::Geode*>(_oggettoObj.get());
if (geode)
{
std::cout << "number of drawables in geode is " <<
geode->getNumDrawables() << std::endl;
for (unsigned int i = 0; i < geode->getNumDrawables(); i++)
{
std::cout << "inside cycle " << i << std::endl;
osg::Geometry *geo = dynamic_cast<osg::Geometry
*>(geode->getDrawable(i));
if (!geo) continue;
else std::cout << "geode has geometry "<< i << std::endl;
osg::StateSet *stateset = geo->getStateSet();
if (!stateset) continue;
else std::cout << "geometry has stateset "<< i << std::endl;
osg::StateAttribute *state =
stateset->getAttribute(osg::StateAttribute::MATERIAL);
if (state)
{
osg::Material *mat = dynamic_cast<osg::Material *>(state);
std::cout << "material name is: " << mat->getName() <<
std::endl;
}
else std::cout << "no material state "<< i << std::endl;
osg::ref_ptr<osgUtil::TangentSpaceGenerator> tsg = new
osgUtil::TangentSpaceGenerator;
tsg->generate(geo, 1);//tex unit for bump map
geo->setVertexAttribArray(8, tsg->getTangentArray());
geo->setVertexAttribArray(7, tsg->getBinormalArray());
std::cout<< "binormals are: " <<
tsg->getBinormalArray()->getTotalDataSize() << std::endl;
std::cout<< "tangents are: " <<
tsg->getTangentArray()->getTotalDataSize() << std::endl;
}
}
else
std::cout <<"no geode found" << std::endl;
