Erg cool het werkt! It works! Ok I try to translate it into English:
---------------
-STEP 1-
You need 3 programs. Eagle itself to make your schematic & board design. Then you need to download/install Eagle3D. This download has 4 directories inside (but 2 important ones):
-povray (the directory with the pov-ray libary files, you need that later to generate an 3D design)
-ulp (this are files you need to great a pov file from a Eagle board design)
---------------
-STEP 2-
You need to start your Eagle open your design (*.brd) and select: File->Run... After that you select the 3d41.ulp file if your Eagle is up-to-date *otherwise you need to use 3d40.ulp for older versions*. This file you just download in step 1 (3d41.ulp file is in the ulp directory).
Finally you select some settings if you want to and then you got a *.pov file in the working directory (project directory).
---------------
-STEP 3-
Now... you can generate a 3d image from this *.pov file! Download/install Pov-Ray, I'm using Linux, so the in command-line it will be:
sudo povray +i your_project_name.pov library_path=/home/your_username/eagle3d/povray Library_Path=/home/your_username/.PlayOnLinux/fonts -geometry 1920x1080
NOTE:
You can see you need to change "your_project_name" to your name you got for your pov file and "your_username" to your username under Linux.
You will also notice that I just use the Windows Font Library of PlayOnLinux (WhineHQ could also work or you can just copy/past your /Windows/Fonts map to your Linux partition).
---------------
-STEP 4-
Eventually if you don't have any errors it will generate a *.PNG file (image file).
It will be beautiful :D
I add my image to this comment...
I hope I helped people who did not understand.. :)
