Body
After creating my Catmull Rom Spline such as: <pre><code>vector3 SplineVector = newSpline.createCatmulRomSpline(vectorOne, vectorTwo, vectorThree, vectorFour, i); </code></pre> However, when I read out the result from <pre><code>vector3 SplineVector </code></pre> I get garbage values. Here is a listing of my spline class, a segment of my vector3 class and in the implementation within the initialization. initialization: <pre><code>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(); } </code></pre> Vector3: <pre><code> 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 return vector3(this->x*invec.x,this->y*invec.y,this->z*invec.z); } _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 return vector3(this->x-=scaler,this->y-=scaler,this->z-=scaler); } _inline vector3& operator*=(const float& scaler){//Multiplication self-assignment return vector3(this->x*=scaler,this->y*=scaler,this->z*=scaler); } _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 return vector3( (this->y*invec.z-this->z*invec.y), (this->z*invec.x-this->x*invec.z), (this->x*invec.y-this->y*invec.x)); } _inline vector3 operator&(vector3& invec){//Dot product return (this->x*invec.x)+(this->y*invec.y)+(this->z*invec.z); } _inline vector3 distance(vector3&);//Distance _inline void normalize(){ float mag = sqrtf(this->x*this->x+this->y*this->y+this->z*this->z); this->x/=mag; this->y/=mag; this->z/=mag; } float x; float y; float z; float getx(); float gety(); float getz(); float getMagnitude(); private: float mag; }; </code></pre> Catmull Rom Spline Generation <pre><code>_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; } </code></pre> I have tried other peoples code and when it comes to outputting the data into the final vector, it outputs bogus values.

1. COThe code looks reasonable. You should print the values of `vectorTwo`, `vectorThree`, and `vectorFour` to see if they look bogus too.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
