Detailed Description

template<class T>
class LinearEqu2D< T >

Donne l'equation de la droite passant par les points.

L'equation est sous forme: y = ax + b

ex.:
Point2D<int> pt1,pt2;
LinearEqu2D equ(&pt1,&pt2);

Donne le point d'intersection entre 2 droites (si ce n'est pas un point retourn FAUX) Example: Point2D<double> a(0,0); Point2D<double> b(10,10); Point2D<double> c(10,0); Point2D<double> d(0,10); Point2D<double> x; LinearEqu2D<double> equ1(a,b); LinearEqu2D<double> equ2(c,d); BOOL res = equ1.GetCrossPtFromLine(equ2,&x); Resultat: res = TRUE; x={5,5} Definition at line 231 of file trigo.h.
