Hello!
I'm trying to get the "PolygonAttributes.CULL_NONE" to work in an 3D applet.
But I can't get it right
I ad here a full class wich extends Shape3D, wich in my opinion use
"PolygonAttributes.CULL_NONE", wich also in my opinion shuld be solid.
I also add the html-file to run it and an applet.
When you have started the applet, start navigate with ARROW_DOWN-key. Then
You will see the Shape3d
