Vector in polar coordinate system.
2D vector which stores its components in polar instead of cartesian coordinates.
| thor::PolarVector2< T >::PolarVector2 | ( | ) |
Default constructor.
Creates a zero vector. The angle phi measures 0 degrees.
| thor::PolarVector2< T >::PolarVector2 | ( | T | radius, |
| T | angle | ||
| ) |
Constructs a polar vector with specified radius and angle.
| radius | The radial component (length of the vector). |
| angle | The angular component in degrees. |
| thor::PolarVector2< T >::PolarVector2 | ( | const sf::Vector2< T > & | vector | ) |
Constructs a polar vector from a cartesian SFML vector.
| vector | Cartesian (x,y) vector being converted to polar coordinates. Zero vectors are allowed and result in a polar vector with r=0 and phi=0. |
| thor::PolarVector2< T >::operator sf::Vector2< T > | ( | ) | const |
Converts the polar vector into a cartesian SFML vector.
