Member Function Documentation

addVertex()

void addVertex ( const T &  p )

inline

Adds a vertex to the polygon.

The point will be added to the end of the list of points

Parameters

p	[in] The point to add

computeCenter()

T computeCenter ( )

inline

Computes the center of the polygon as the average of all coordinates.

Returns

Center of the polygon

removeVertex()

void removeVertex ( size_t  idx )

inline

Removes vertex from the polygon.

Parameters

idx	[in] Index of the vertex to remove

size()

size_t size ( ) const

inline

Number of vertices of this polygon.

Returns

Number of vertices
