构造函数

•         gsKnotVector (int p)

 Constructor with degree only. 
 

•   gsKnotVector (int p, unsigned sz)

  Constructor with degree and size (=number of knots) 
 

•   gsKnotVector (T u0, T u1, unsigned interior, unsigned mult_ends=1, unsigned mult_interior=1, int degree=-1)
  

  构造函数为‘下限，上限，内部不同点个数，末端重节点个数，内部重节点个数，阶次；‘阶次’的缺省值为末端重节点个数-1. 

•   gsKnotVector (std::vector< T > const &knots, int degree, int regularity)

  Construct an open knot vector from the given unique knots. More...
 

•   gsKnotVector (int degree, std::vector< T > const &knots)

  Construct a knot vector with the given degree and knots. 
 

•   gsKnotVector (int deg, const_iterator start, const_iterator end)

 

•   gsKnotVector (gsCompactKnotVector< T > ckv)

或者利用

“   gsKnotVector<double> kv2;

       kv2.push_back(1,3);

       kv2.push_back(2);

       kv2.push_back(3,3);

       kv2.set_degree(2);”

template <classT>void

gsKnotVector<T>::initUniform(Tu0,T u1, unsignedinterior,unsignedmult_ends,unsignedmult_interior,intdegree)

{   

    my->knots.clear();

    my->knots.reserve( 2 *mult_ends +interior*mult_interior); 

    const T h = (u1-u0) / (interior+1); 

    my->knots.insert(my->knots.begin(),mult_ends,u0);   

    for ( unsigned i=1; i<=interior;i++ )

        my->knots.insert(my->knots.end(),mult_interior,

                        u0 + i*h ); 

    my->knots.insert(my->knots.end(),mult_ends,u1); 

    if (degree == -1)  

        my->p =mult_ends-1;

    else

        my->p =degree;

}

gsKnotVector.set_degree() 的使用

gsKnotVector<double> kv2;

  kv2.set_degree(2); // this willcause a break.

       gsKnotVector<double> kv2;

kv2.push_back(1,3);

kv2.push_back(2);

kv2.push_back(3,3);

kv2.set_degree(2); // this works
