Java 3D

Hej alle!

Jeg har lige set en tutorial på youtube, fordi jeg gerne vil prøve at lave et 3D spil eller lignende i Java. Efter at have set videoen igennem virker koden ikke, så jeg tjekker koden og videoen igen, men det virker stadig ikke... Der skulle gerne poppe en sort firkant op på skærmen, men det sker bare ikke.. Jeg kører den her som en java application og ikke som en applet. Modtager ingen Exceptions, og min Thread starter og kører rundt, det har jeg tjekket

PS. Sorry for the comments
