错误：没有匹配的函数可以调用

Question

我是一名C ++初学者，无法想象我们的错误。我尝试定义一个类Triangle和一个Vector3D类。我想用三个Vector3D对象构造一个Triangle对象。

我得到：“错误：在Triangle.cpp文件中调用'Vector3D :: Vector3D（）”没有匹配函数

我不明白错误信息。在我的理解中，我只是传递对象，而不是调用函数Vector3D（）...这是代码。我会很高兴得到任何帮助。

Triangle.h

#ifndef TRIANGLE_H
#define TRIANGLE_H
#include "Vector3D.h"

class Triangle
{
    public:
        Triangle(Vector3D a, Vector3D b, Vector3D c);
        Vector3D p1, p2, p3;
        virtual ~Triangle();
    protected:
    private:
};
#endif // TRIANGLE_H

Triangle.cpp

#include "Triangle.h"
Triangle::Triangle(Vector3D a, Vector3D b, Vector3D c)
{
    p1 = a;
    p2 = b;
    p3 = c;
}
Triangle::~Triangle(){}

Vector3D.h

#ifndef VECTOR3D_H
#define VECTOR3D_H

class Vector3D
{
    public:
        double x, y, z;
        Vector3D(double a, double b, double c);
        virtual ~Vector3D();
    protected:
    private:
};
#endif // VECTOR3D_H

Vector3D.cpp

#include "Vector3D.h"
#include <math.h>

Vector3D::Vector3D(double a, double b, double c)
{
    x = a;
    y = b;
    z = c;
}
Vector3D::~Vector3D(){}
