cee::Vec2d
-
class Vec2d
Vector class for a 2D double vector.
Public Functions
-
Vec2d()
Constructs a null vector.
-
Vec2d(double x, double y)
Constructs a vector from an x and y coordinate.
-
Vec2d &operator=(const Vec2d &other)
Assigns other to this vector and returns a reference to this vector.
-
bool operator==(const Vec2d &rhs) const
Returns true if two vectors are equal, otherwise returns false.
An exact match is required x() == rhs.x(), etc.
-
bool operator!=(const Vec2d &rhs) const
Returns true if two vectors are not equal, otherwise returns false.
Exact comparison is used (!= between doubles)
-
const Vec2d operator-(const Vec2d &rhs) const
Returns a vector that is this vector subtracted with rhs.
-
const Vec2d operator*(double scalar) const
Returns a vector that is this vector multiplies with scalar.
-
const Vec2d operator/(double scalar) const
Returns a vector that is this vector divided with scalar.
-
double operator*(const Vec2d &rhs) const
Computes the dot product of this and rhs and return the result (scalar)
Formula:
S = this.x*rhs.x + this.y*rhs.y
-
const double &x() const
X element of the vector.
-
const double &y() const
Y element of the vector.
-
double &x()
X element of the vector.
-
double &y()
Y element of the vector.
-
void set(double x, double y)
Sets x and y value.
-
bool normalize()
Normalizes this vector.
Returns false if the vector is a null vector. Otherwise returns true.
-
double length() const
Returns the length of this vector.
