Hi! I have gotten rid of a circular dependence but am still having issues with another problem.
I am still learning and hope that someone can explain to me more about what is wrong with my implementation. Sorry for the trouble, but I really appreciate everyone who is helping me.
So, the issue I am having now is that in my Vec3 class, it is trying to use Quaternions, but it does not have the "complete type" of the quaternion.
The following is what I have:
vec3.h
#ifndef VEC3_H
#define VEC3_H
#include "point.h"
#include <math.h>
class Quaternion;
class Vec3
{
friend ofstream& operator <<(ofstream& output, const Vec3& p);
friend ifstream& operator >>(ifstream& input, Vec3& p);
public:
Vec3();
Vec3(double _x, double _y);
Vec3(double _x, double _y, double _z);
double x,y,z;
//Operators
Vec3 operator -(Vec3 a) const;
Vec3 operator /(double s) const;
Vec3 operator *(double s) const;
Vec3 operator *(Quaternion q) const;
// Used to do vector Vec3 addition
Vec3 operator +(Vec3 a) const;
Point operator +(Point a) const;
Vec3& operator =(Point a);
Vec3 crossProduct(Vec3 v1); // Itself cross v1
double dotProduct(Vec3 v);
double length();
void normalize();
};
#endif
Quaternion.h
#ifndef QUATERNION_H
#define QUATERNION_H
#include "vec3.h"
class Quaternion
{
public:
Quaternion(Vec3 v);
Quaternion(double w, Vec3 v);
Vec3 v;
double scalar;
Quaternion operator *(Quaternion s);
Quaternion conjugate();
};
#endif
vec3.cpp The error is on each line of this function.
...
Vec3 Vec3::operator *(Quaternion q) const
{
// Change this vector into a quaternion
Quaternion currentQuat(0, Vec3(x,y,z));
Quaternion newQuat = currentQuat*q;
Quaternion result = q.conjugate()*newQuat;
return result.vec();
}
