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

		Color	fcolor,
		int	polygonEdgesType = 0,
		const std::string &	textureName = ""

Member Function Documentation

activateQuadBorder()

void tlp::GlComplexPolygon::activateQuadBorder	(	const float	borderWidth,
		const Color &	color,
		const std::string &	texture = "",
		const int	position = 1,
		const float	texCoordFactor = 1.f,
		const int	polygonId = 0
	)

Draw a thick (textured) border around the polygon.

The graphic card must support geometry shader to make this feature to work. The position parameter determines the way the border is drawn (depending on the polygon points ordering):

• 0 : the border is drawn outside (or inside) the polygon
• 1 : the border is centered on the polygon outline
• 2 : the border is drawn inside (or outside) the polygon

The texCoordFactor parameter determines the way the texture is applied : if < 1, the texture will be expanded and > 1, the texture will be compressed The polygonId parameter determines on which contour of the polygon, the border will be applied

addPoint()

Add a new point in polygon.

beginNewHole()

virtual void tlp::GlComplexPolygon::beginNewHole ( )
