## Detailed Description

Class to create a complex polygon (concave polygon or polygon with hole) If you want to create a complex polygon you have 4 constructors : Constructors with vector of coords : to create a complex polygon without hole

- In this case you have two constructor : with and without outline color
- You can create a polygon like this :

           vector <Coord> coords;
           coords.push_back(Coord(0,0,0));
           coords.push_back(Coord(10,0,0));
           coords.push_back(Coord(10,10,0));
           coords.push_back(Coord(0,10,0));
           GlComplexPolygon *complexPolygon=new GlComplexPolygon(coords,Color(255,0,0,255));
           layer->addGlEntity(complexPolygon,"complexPolygon");

Constructors with vector of vector of Coords : to create a complex polygon with hole

- In this case you have two constructor : with and without outline color
- The first vector of coords is the polygon and others vector are holes
- You can create a polygon with hole like this :

           vector <vector <Coord> > coords;
           vector <Coord> polygon;
           vector <Coord> hole;
           polygon.push_back(Coord(0,0,0));
           polygon.push_back(Coord(10,0,0));
           polygon.push_back(Coord(10,10,0));
           polygon.push_back(Coord(0,10,0));
           hole.push_back(Coord(4,4,0));
           hole.push_back(Coord(6,4,0));
           hole.push_back(Coord(6,6,0));
           hole.push_back(Coord(4,6,0));
           coords.push_back(polygon);
           coords.push_back(hole);
           GlComplexPolygon *complexPolygon=new GlComplexPolygon(coords,Color(255,0,0,255));
           layer->addGlEntity(complexPolygon,"complexPolygon");

In constructors you can specify the polygon border style : polygonEdgesType parameter (0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves) You can also specify the texture name if you want to create a textured complex polygon

In complex polygon you can add a smooth border : see activateQuadBorder(..) function And you can specify the texture zoom : see setTextureZoom(...) function

Define polygon according to one contour and compute tesselation.

Use this method if your polygon is defined by one contour. This method resets any previously defined contours and recompute tesselation.

Parameters:

  contour | a vector of tlp::Coord defining the contour.
  polygonEdgesType | an integer determining the shape of the polygon edges (0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves)

Define polygon according to several contours and compute tesselation.

Use this method if your polygon is defined by several contours (e.g. polygon with holes). This method resets any previously defined contours and recompute tesselation.

Parameters:

  contours | a vector of vector of tlp::Coord defining the different contours.
  polygonEdgesType | an integer determining the shape of the polygon edges (0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves)
