title: JavaFX 3d samples
body: <p>I have just started with Java and the first thing i did was to download the Java SE JDK 7u40 bundled with Netbeans.<br>
  I am on ubuntu 13.04.<br>
  When i tried out the samples from JavaFX  on Netbeans specifically the Cube3D sample when i ran it strange results came out.I had an empty window with small yellow square on the top left of the window 
  rather than a 3d Cube on the window.<br>
  Similar problems occur with all the samples that have 3d in them.<br>
  However when i do this on windows enviroment everything runs properly (windows 7 to be precise).
  Someone any reason of why is this happening?</p>
