Not getting 3D graphics Window

[incimuhammet]

Hi,
Even though I downloaded these files, I still get the same error. Can you help me with this?

sudo apt-get install vtk6
sudo apt-get install libvtk6-java
sudo apt-get install openjdk-8-jre
sudo apt-get install openjdk-8-jdk
sudo apt install libglu1-mesa

[HELYX-OS]

Hi,
you were not supposed to install neither java nor vtk, they come packed with the HELYX-OS installation.
The libglu1-mesa, maybe...it depends on the error you get (I assume you are getting one, because your 3D is not showing).
Try run the "HELYX-OS.sh" script with the -V argument and check the error you get.
