Detailed Description

polyline that stores points of type V Generated from class MR.Polyline2. This is the const half of the class.

Constructor & Destructor Documentation

Const_Polyline2()

unsafe MR.Const_Polyline2.Const_Polyline2 ( MR.Std.Const_Vector_MRVertId comp2firstVert, MR._ByValue_VertCoords2 ps )

inline

creates comp2firstVert.size()-1 not-closed polylines each pair (a,b) of indices in

Parameters

comp2firstVert	defines vertex range of a polyline [a,b)
ps	point coordinates Generated from constructor MR.Polyline2.Polyline2.

Member Function Documentation

computeBoundingBox()

unsafe MR.Box2f MR.Const_Polyline2.computeBoundingBox ( MR.AffineXf2f? toWorld = null )

inline

passes through all valid points and finds the minimal bounding box containing all of them

if toWorld transformation is given then returns minimal bounding box in world space Generated from method MR.Polyline2.computeBoundingBox.

contours()

unsafe MR.Std.Vector_StdVectorMRVector2f MR.Const_Polyline2.contours ( MR.Std.Vector_StdVectorMRVertId? vertMap = null )

inline

convert Polyline to simple contour structures with vector of points inside

if all even edges are consistently oriented, then the output contours will be oriented the same

Parameters

vertMap

optional output map for for each contour point to corresponding VertId Generated from method MR.Polyline2.contours.
