Member Function Documentation

createFromAsciiFile()

static Gate2D pottu::Gate2D::createFromAsciiFile ( const std::string &  filename )

inlinestatic

Reads the polygon from a file.

File must contain two columns, x and y, separated by whitespace. After the read this function calls update() automatically.

operator()()

bool pottu::Gate2D::operator() ( double  x, double  y  ) const

inlinenoexcept

Tests if a given point is inside the gate.

Parameters

x	x coordinate of the point to be tested
y	y coordinate of the point to be tested

Returns

true if point is inside

update()

void pottu::Gate2D::update ( )

inline

updates the other important fields after modifying points.

Call this after setting vector points. This will throw runtime_error if points has less than four points (the last must be duplicate of the first).
