Vector()

Null

Vector(T x, T y)

Given components

template<class F> Vector(const Vector3<F> &v)

Create from another Vector

Vector(T* v)

Create from an array

Vector finitized() const

Making all components finite

Vector operator*(const double &s) const

Multiplication by scalar

template<class U> const Vector& operator*=(const U &s)

In-place multiplication by scalar

Vector normalized() const

Normalize the normalized version of this vector

Vector<T> operator-() const

Vector negation

Vector operator+(const Vector<T>&v) const

Vector addition

Vector operator-(const Vector<T>&v) const

Vector subtraction

Vector cw90() const

Return a vector like this, but rotated 90 degrees clockwise

double length() const

Return the length of this vector

double dot(const Vector<T> &v) const

Dot this vector with another

double cross(const Vector<T> &v) const

Cross this 2D vector with another - gives the sine of the angle between the two, multiplied by the lengths. Useful for telling which side of a given vector you are on.
