Constructor & Destructor Documentation

portion::portion (  double *    coordinates, int    index )

Parameters: coordinates  A 9-double array containing the x1,y1,z1, ..., xk,yk,zk coordinates of the 3 points describing the portion triangle index  The portion (unique) index

---

Member Function Documentation

void portion::displayAnt (  bool    printNames )

The OpenGL/Glut code that draws the ants located on the portion, if any. Parameters: printNames  Determines wether the ants should be labeled or not.

void portion::displayPheromones (  char    pheromoneType )  [virtual]

The OpenGL/Glut code that displays the pheromones located on the portion, if any. Parameters: pheromoneType  Selects the pheromone type to display. 0 for none, 1 for departure, 2 for return. Reimplemented in land.

double portion::getFood (    )  [virtual]

Returns how much food has been stored on the portion so far. 0 if the portion is NOT a colony. Reimplemented in colony.

double portion::modifyFood (  double    modifier )  [virtual]

Changes the amount of food which has been stored by ants on this portion. Does nothing if the portion is not a colony. Parameters: modifier  the number that will be added to the current food store. Can be negative. Reimplemented in colony.

portion * portion::senseBasicInstinct (  portion *    previousPortion )

Returns a random portion meeting the walkable condition. Parameters: previousPortion  Indicates where the ant comes from. It will be given less chance to return to its previous portion.

portion * portion::sensePheromones (  char    type, char    antHemisphere, portion *    previousPortion )

Returns the portion that contains the most pheromone of type "type" laid by ants from the hemisphere antHemisphere. Parameters: previousPortion  Indicates where the ant comes from. It will be given less chance to return to its previous portion. type  'd' for departure-, 'r' for return-pheromones antHemisphere  The kind of pheromones the ant can sense, ie 0 for South, 1 for North.

void portion::setColor (    )

Resets the current OpenGL color. This method could be used before displaying the triangle for example
