rechthoeken "Rechth_9g

rechthoeken "lr" = 0, "r" = 9 rechthoeken "lr" = 1, "r" = 9

De draaipunten staan in het (0,0) punt

gouden rechthoeken "Rechth_9g_gk" terug naar de inleiding

Met deze class kan je max 9 gouden rechthoeken creeeren, zo ontstaan 8 vierkanten

"Rechth_9g_gk" is een hulpmiddel om spiralen en andere gouden vormen in een schets te positioneren. gk dwz van groot naar klein, zie argument 4

De argumenten van de constructor

1) "n" = lengte van de korte zijde van de rechthoek, 2) "sw" = dikte van de lijnen, 3) "lr" = 0 rechthoeken staan links, "lr" = 1 rechthoeken staan rechts

4) "r" = aantal rechthoeken (max 9), van groot naar klein, dus met "r" = 1 is de grootste rechthoek zichtbaar

5) en 6) x, y positie, 7) hoek, 8) kleur van de lijnen

n, a, b, c, d, e, f, g en h zijn de korte zijden van de 9 gouden rechthoeken en de zijden van de 8 ontstane vierkanten
