Member Function Documentation

Vector ns3::Rectangle::CalculateIntersection ( const Vector &  current,
const Vector &  speed 
) const
Parameters
currentthe current position
speedthe current speed
Returns
the intersection point between the rectangle and the current+speed vector.

This method assumes that the current position is located inside the rectangle and checks for this with an assert. This method compares only the x and y coordinates of the input position and speed. It ignores the z coordinate.

Rectangle::Side ns3::Rectangle::GetClosestSide ( const Vector &  position) const
Parameters
positionthe position to test.
Returns
the side of the rectangle the input position is closest to.

This method compares only the x and y coordinates of the input position. It ignores the z coordinate.

bool ns3::Rectangle::IsInside ( const Vector &  position) const
Parameters
positionthe position to test.
Returns
true if the input position is located within the rectangle, false otherwise.

This method compares only the x and y coordinates of the input position. It ignores the z coordinate.
