schets met vier trapeziums en vier 3d hoeken.                                      terug naar de inleiding
toets "s" stopt de rotaties iedere andere toets start de rotaties weer
                                                                                                         hoeken en trapeziums in fullscreen
 
de schets maakt gebruik van de objectmethodes van de p5.js superclass:  "Vormen" en objecten van de subclasses:  "Hoek3d_na2n" ,  "Trap_2nn""Rechthoek"   en  "Ruitjes"
