Dear All,
I would like to turn a Drawable object into a Geometry counterpart in order to
retrieve its texture coordinates.
I have tried to use both the asGeometry method of the Drawable class and the
dynamic cast operator but both attempts ended up delivering a NULL pointer. I
am not sure if there is another way of doing it.
Here is a code snippet.
osg::Geode myGeode = new osg::Geode;
myGeode->addDrawable(new osg::ShapeDrawable(new osg::Box(osg::Vec3(),1,1,1)));
osg::Drawable* myDrawable = myGeode->getDrawable(0);
osg::Geometry* myGeom = myDrawable->asGeometry(); //This returns NULL!
osg::Geometry* myGeom2 = dynamic_cast<osg::Geometry *>(myDrawable);
Unfortunately both myGeom and myGeom3 are both NULL at this point.
What to do then, anyone to save me from embarrasment?
Anxiously waiting for your reply.
Franclin.
