--------------------------------------------------------------------------------

" Geroty (const vector<Point3D>& poly, const Plane& Tr)"

As i'm c++ beginner the following Function Declaration and Definition couldnt understandable? so explain me what kind of Declaration this is."const vector<Point3D>& poly....." ? and where do I find study materials for the kind of function declaration"

Also pleas explain *this without more complex technical terms.

const vector<Point3D>&

is a reference to a vector containing Point3D objects. The const means the container is constant. That is, you can access the objects inisde but you can't change them.

vector is a C++ Standard Library container.

Find out about vector and references in any C++ textbook.

*this is the object pointed at by the this pointer. this pointers are used in member functions to access the object being used by the member function. Again, you will need to read up on classes and member functions in a C++ textbook.

I recommend the "C++ Primer Plus" 5th Ed. by Stephen Prata. This one is non-technical and assumes you know nothing. I would make a serious attempt to read this book.

There are also C++ classes offered where this material is covered. Check your local colleges.
