Class Grafik3D

java.lang.Object
  Grafik3D

public class Grafik3D
extends java.lang.Object

En klass som hjälper till vid ritning av 3-dimmensionella saker

OBS! Enbart drawTriangle(Triangle t) är 100% testad. Övriga metoder borde fungera, men saknar skuggning. Har inte heller hunnit testa alla metoder i praktiken.
