JPanel / JFrame looks wrong
Peace be upon all
I'm trying to put a jpanel into a 3d shape under the lg3d project, but the result always comes not like the interpretations I found on the web about this task.
The swing node (jpanel, or jframe) always appears outside the lg3d project's window in a seperate window, not inside the shape or the Frame3D.
What can I do, and what is the error.
