Function Documentation

abs()

float abs ( const RVO::Vector2 &  q )

inline

Parameters

q

A vector

Returns

The absolute value of the vector.

absSq()

float absSq ( const RVO::Vector2 &  q )

inline

Parameters

q

A vector

Returns

The squared absolute value of the vector.

atan()

float atan ( const RVO::Vector2 &  q )

inline

Parameters

q

A vector

Returns

The angle the vector makes with the positive x-axis. Is in the range [-PI, PI].

det()

float det ( const RVO::Vector2 &  p, const RVO::Vector2 &  q  )

inline

Parameters

p	A vector
q	A vector

Returns

Returns the determinant of the 2x2 matrix formed by using p as the upper row and q as the lower row.

norm()

RVO::Vector2 norm ( const RVO::Vector2 &  q )

inline

Parameters

q

A vector

Returns

The normalized vector.

normal()

RVO::Vector2 normal ( const RVO::Vector2 &  p, const RVO::Vector2 &  q  )

inline

Parameters

p	A point
q	A point

Returns

The normal vector to the line segment pq.

operator*()

RVO::Vector2 operator* ( float  a, const RVO::Vector2 &  q  )

inline

Scalar multiplication.

Parameters

a	The left hand side scalar
q	The right hand side vector

Returns

The scalar multiplication of the lhs scalar and the rhs vector.

operator<<()

std::ostream& operator<< ( std::ostream &  os, const RVO::Vector2 &  q  )

inline

Writes a vector to the standard output.

Parameters

os	The output stream
q	The vector

Returns

The standard output.
