class "Boxr" met voorbeeldschets

schets met boxen in een driehoekformatie. terug naar de inleiding

De boxen zijn objecten van de class "Boxr" , de code van deze class staat onder deze schets.

2*hn is de breedte van de box (hn is de hoogte van de gelijkzijdige driehoek n)

argumenten van de constructor:

1) = grootte van de box, 2) = grootte van de ruiten, 3) en 4) = positie van de box,

5) = kleur van de ruiten, 6) = kleur van de top, 7) = kleur li vlak, 8) = kleur re vlak

float r = grootte van de ruit als deel van de vlakken van de box. Met r = 0; is de ruit onzichtbaar

Met r = 1 is de ruit net zo groot als de box en heeft de box de kleur klr
