Hi,
I'm new to this list and to openscenegraph and I've a question regarding a
problem and I don't know how to solve it.
It should be really trivial, but I don't get it managed, and google or
other searches could not help me.
I've a cylinder, and while showing the scene, I want to change the size
(height) of the cylinder.
I tried it that way, but only the first call of setting the height is a
success (so the height of the cylinder stays at 0.1):
===
osg::Geode* possible_binding = new osg::Geode();
osg::Cylinder* possible_binding_shape = new
osg::Cylinder(osg::Vec3(0,0,0), 0.4, 1.0);
osg::ShapeDrawable* possible_binding_drawable = new
osg::ShapeDrawable(possible_binding_shape);
possible_binding->addDrawable(possible_binding_drawable);
[...]
viewer.realize();
float i = 0;
while(!viewer.done()){
i += 0.1f;
((osg::Cylinder*)(possible_binding->getDrawable(0)->getShape()))->setHeight(i);
std::cout << "Main: " <<
((osg::Cylinder*)(possible_binding->getDrawable(0)->getShape()))->getHeight()
<< std::endl;
viewer.frame();
}
===
What am I doing wrong?
Sorry if this should be a trivial question, but I don't know the answer.
Thanks a lot!
Patrick
