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

Default constructor

Warning:
don't use this constructor if you want to create a complex polygon, see others constructors

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

Constructor with a vector of coords, a fill color, a polygon edges type(0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves) and a textureName if you want

tlp::GlComplexPolygon::GlComplexPolygon ( const std::vector< Coord > &  coords,
Color  fcolor,
Color  ocolor,
int  polygonEdgesType = 0,
const std::string &  textureName = "" 
)

Constructor with a vector of coords, a fill color, an outline color, a polygon edges type(0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves) and a textureName if you want

tlp::GlComplexPolygon::GlComplexPolygon ( const std::vector< std::vector< Coord > > &  coords,
Color  fcolor,
int  polygonEdgesType = 0,
const std::string &  textureName = "" 
)

Constructor with a vector of vector of coords (the first vector of coord is the polygon and others vectors are holes in polygon), a fill color, a polygon edges type(0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves) and a textureName if you want

tlp::GlComplexPolygon::GlComplexPolygon ( const std::vector< std::vector< Coord > > &  coords,
Color  fcolor,
Color  ocolor,
int  polygonEdgesType = 0,
const std::string &  textureName = "" 
)

Constructor with a vector of vector of coords (the first vector of coord is the polygon and others vectors are holes in polygon), a fill color, an outline color a polygon edges type(0 -> straight lines, 1 -> catmull rom curves, 2 -> bezier curves) and a textureName if you want

Member Function Documentation

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

virtual void tlp::GlComplexPolygon::addPoint ( const Coord &  point  )  [protected, virtual]

Add a new point in polygon

void tlp::GlComplexPolygon::addVertex ( const Coord &  vertexCoord,
const Vec2f &  vertexTexCoord

VERTEX* tlp::GlComplexPolygon::allocateNewVertex (  )  [protected]
virtual void tlp::GlComplexPolygon::beginNewHole (  )  [protected, virtual]

Begin a new hole in the polygon

void tlp::GlComplexPolygon::createPolygon ( const std::vector< Coord > &  coords,
int  polygonEdgesType 
) [protected]
void tlp::GlComplexPolygon::desactivateQuadBorder ( const int  polygonId = 0  ) 

Desactivate the textured quad border

virtual void tlp::GlComplexPolygon::draw ( float  lod,
Camera *  camera 
) [virtual]

Draw the complex polygon

Implements tlp::GlSimpleEntity.

void tlp::GlComplexPolygon::endPrimitive (  )  [protected]
Color tlp::GlComplexPolygon::getFillColor (  )  [inline]

Get fill color of GlComplexPolygon

Color tlp::GlComplexPolygon::getOutlineColor (  )  [inline]

Get outline color of GlComplexPolygon

float tlp::GlComplexPolygon::getTextureZoom (  )  [inline]

Get the texture zoom factor

virtual void tlp::GlComplexPolygon::getXML ( xmlNodePtr  rootNode  )  [virtual]

Function to export data and type in XML

Implements tlp::GlSimpleEntity.

virtual void tlp::GlComplexPolygon::getXMLOnlyData ( xmlNodePtr  rootNode  )  [virtual]

Function to export data in XML

void tlp::GlComplexPolygon::runTesselation (  )  [protected]
void tlp::GlComplexPolygon::setFillColor ( const Color &  color  )  [inline]

Set fill color of GlComplexPolygon

void tlp::GlComplexPolygon::setOutlineColor ( const Color &  color  )  [inline]

Set outline color of GlComplexPolygon

Set if the polygon is outlined or not

void tlp::GlComplexPolygon::setOutlineSize ( double  size  ) 

Set size of outline

void tlp::GlComplexPolygon::setTextureZoom ( float  zoom  )  [inline]

Set the texture zoom factor By default if you have a polygon with a size bigger than (1,1,0) the texture will be repeated If you want to don't have this texture repeat you have to modify texture zoom For example if you have a polygon with coords ((0,0,0),(5,0,0),(5,5,0),(0,5,0)) you can set texture zoom to 5. to don't have texture repeat
