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

Constructor & Destructor Documentation

tlp::GlComplexPolygon::GlComplexPolygon ( )
inline

Default constructor.

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

tlp::GlComplexPolygon::GlComplexPolygon ( const std::vector< Coord > &  coords,
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)
protectedvirtual

Add a new point in polygon.

virtual void tlp::GlComplexPolygon::beginNewHole ( )
protectedvirtual

Begin a new hole in the polygon.

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.

Color tlp::GlComplexPolygon::getFillColor ( ) const
inline

Get fill color of GlComplexPolygon.

Definition at line 123 of file GlComplexPolygon.h.

Color tlp::GlComplexPolygon::getOutlineColor ( ) const
inline

Get outline color of GlComplexPolygon.

Definition at line 137 of file GlComplexPolygon.h.

std::string tlp::GlComplexPolygon::getTextureName ( )

Get the textureName.

float tlp::GlComplexPolygon::getTextureZoom ( )
inline

Get the texture zoom factor.

virtual void tlp::GlComplexPolygon::getXML ( std::string &  outString)
virtual

Function to export data and type outString (in XML format)

Implements tlp::GlSimpleEntity.

virtual void tlp::GlComplexPolygon::getXMLOnlyData ( std::string &  outString)
virtual

Function to export data in outString (in XML format)

void tlp::GlComplexPolygon::setFillColor ( const Color &  color)
inline

Set fill color of GlComplexPolygon.

Definition at line 130 of file GlComplexPolygon.h.

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

Set outline color of GlComplexPolygon.

Definition at line 144 of file GlComplexPolygon.h.

void tlp::GlComplexPolygon::setOutlineMode ( const bool  )

Set if the polygon is outlined or not.

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

Set size of outline.

void tlp::GlComplexPolygon::setTextureName ( const std::string &  name)

Set the textureName.

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
