Генерация сплайна Catmull Rom и возврат мусора

После создания моего сплайна Catmull Rom, такого как:

vector3 SplineVector = newSpline.createCatmulRomSpline(vectorOne, vectorTwo, vectorThree, vectorFour, i);

Тем не менее, когда я зачитал результат из

vector3 SplineVector

Я получаю значения мусора.

Вот список моего класса сплайнов, сегмента моего класса vector3 и реализации в рамках инициализации.

инициализации:

for(float i = 0.0f; i <= 1.0f; i += 0.1f)
{
vector3 SplineVector = newSpline.createCatmulRomSpline(vectorOne, vectorTwo, vectorThree, vectorFour, i);
cout << "\n\ncurve pos X: " << SplineVector.getx();
cout << "\ncurve pos Y: " << SplineVector.gety();
cout << "\ncurve pos Z: " << SplineVector.getz();

}

Vector3:

   class vector3
{
public:
vector3::vector3():x(0),y(0),z(0)
{
}
vector3::~vector3()
{
}

vector3(float);
vector3(float inx,float iny,float inz): x(inx), y(iny), z(inz)
{
}

//Vector operators
_inline vector3 operator=(const vector3& invec){ // Assignment
return vector3(this->x=invec.x,this->y=invec.y,this->z=invec.z);
}

_inline vector3 operator+(const vector3& invec){//Addition
return vector3(this->x+invec.x,this->y+invec.y,this->z+invec.z);
}
_inline vector3 operator-(const vector3& invec){//Subtraction
return vector3(this->x-invec.x,this->y-invec.y,this->z-invec.z);
}

_inline vector3 operator*(const vector3& invec){//Multiplication

}
_inline vector3 operator/(const vector3& invec){//Division
return vector3(this->x/invec.x,this->y/invec.y,this->z/invec.z);
}

//Scaler operators
_inline vector3& operator+=(const float& scaler){//Addition self-assignment
return vector3(this->x+=scaler,this->y+=scaler,this->z+=scaler);
}
_inline vector3& operator-=(const float& scaler){//Subtraction self-assignment

}
_inline vector3& operator*(const float& scalar){
return vector3(this->x*scalar, this->y*scalar, this->z*scalar);
}

//Math methods
_inline vector3 operator^(vector3& invec){//Cross product

_inline vector3 operator&(vector3& invec){//Dot product

_inline vector3 distance(vector3&);//Distance

Catmull Rom Spline Поколение

_inline vector3 createCatmulRomSpline(vector3 P0, vector3 P1, vector3 P2, vector3 P3, float t)
{

float t2 = t*t;
float t3 = t2*t;

vector3 result = ((P1*2) + (P2 - P0) * t + (P0*2 - P1 * 5 + P2*4 - P3)*t2 + (P1*3 - P0- P2*3 + P3) * t3)*0.5f;
return result;
}

Я пробовал код других людей, и когда дело доходит до вывода данных в окончательный вектор, он выводит фиктивные значения.
