Detailed Description

A polygon, for use in detector masks.

Polygon defined by two arrays with x and y coordinates of points. Sizes of arrays should coincide. If polygon is unclosed (the last point doesn't repeat the first one), it will be closed automatically.

Constructor & Destructor Documentation

Polygon() [1/2]

Polygon::Polygon	(	const std::vector< double >	x,
		const std::vector< double >	y
	)

Parameters

x	Vector of x-coordinates of polygon points.
y	Vector of y-coordinates of polygon points.

Polygon() [2/2]

Polygon::Polygon

(

const std::vector< std::vector< double >>

points

)

Polygon defined by two dimensional array with (x,y) coordinates of polygon points.

The size of second dimension should be 2. If polygon is unclosed (the last point doesn't repeat the first one), it will be closed automatically.

Parameters

points

Two dimensional vector of (x,y) coordinates of polygon points.
