Class Vector3

• Defined in File Vector3.h

Class Documentation

class Vector3

This class represents a three-dimensional vector.

The three-dimensional vector can be used to represent a translation in three-dimensional space or to represent the attitude of an object using Euler angle.

Public Functions

inline Vector3()

Default constructor.

inline Vector3(const Vector3 &other)

Copy constructor.

Parameters:

other – a vector of dimension 3

inline Vector3(float x, float y, float z)

Constructor.

Constructs a three-dimensional vector from three single values x, y, z or roll, pitch, yaw

inline Vector3 &operator=(const Vector3 &other)

Assignment operator.

Parameters:

other – a vector of dimension 3

inline Vector3 cross(const Vector3 &other) const

Three-dimensional vector (cross) product.

Calculates the tree-dimensional cross product, which represents the vector orthogonal to the plane defined by this and other.

Returns:

this x other
