Constructor & Destructor Documentation

pyramidworks::geometry::ConvexPolygon::ConvexPolygon

(

const std::vector< ugdk::Vector2D > &

vertices

)

Parameters:

vertices

The list of vertices of the polygon, in local coordinates (0,0 is the "center", where this polygon is positioned). vertices[i] and vertices[i+1] form a edge, and vertices[n]-vertices[0] is the closing edge.
