Hello guys!
I have run a search over the topics, but I didn't find an answer for my
question, so here it is:
I have my own derived class called PiFaceGeometry, which is derived from
osg::Geometry class, I use this to work with faces of solids - so I have the
type of face - cylinder, plane, and other which I store within this class and
also some other properties.
I have a different class called SolidComponent, which is derived from
osg::MatrixTransform and represent machinery workpieces and tools.
The problem is that sometimes I need to clone the SolidComponent (which
contains Geode as child with PiFaceGeometries, and can also contain other
SolidComponents as children). I think, I need a deep copy, because sometimes I
have to change the color of triangles, or am I wrong? The question is, how
should I reimplement the clone() function? I looked also into the osg source
code but I didn't understand the way, how to do this.
How can I force the program to call PiFaceGeometry::clone() if this is only a
child of object, on which I called clone()?
I am sorry If this question is silly, I am not a good C++ programmer and I hate
C++ :-P.
Thank you for your responses!
Cheers,
Peter
Code:
class PiFaceGeometry: public osg::Geometry {
public:
osg::ref_ptr<osg::IntArray> edges;
PiSurfaceType surfType;
void changeFaceColor(osg::Vec4 color){...};
PiFaceGeometry * clone(const osg::CopyOp ©op ){
//how can I reuse Geometry::Clone(), if it returns a Geometry but I need
PiFaceGeometry?
}
};
