Exceptions when running viewer #18

I'm trying to run shapenet-viewer to render shapenet shapes. However, when I run the viewer.sh on my Ubuntu 16.04, the following exceptions show up:

Uncaught exception thrown in Thread[jME3 Main,5,main] java.lang.ExceptionInInitializerError at com.jme3.system.lwjgl.LwjglDisplay.createContext(LwjglDisplay.java:112) at com.jme3.system.lwjgl.LwjglAbstractDisplay.initInThread(LwjglAbstractDisplay.java:113) at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:211) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.RuntimeException: org.lwjgl.LWJGLException: No modes available at org.lwjgl.opengl.Display.(Display.java:141) ... 4 more Caused by: org.lwjgl.LWJGLException: No modes available at org.lwjgl.opengl.LinuxDisplay.init(LinuxDisplay.java:740) at org.lwjgl.opengl.Display.(Display.java:138) ... 4 more

Exception: java.lang.NullPointerException thrown from the UncaughtExceptionHandler in thread "jME3 Main"

My java version is:

java version "1.8.0_144" Java(TM) SE Runtime Environment (build 1.8.0_144-b01) Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

And the configure file I use just contains the following lines:

viewer.commands = [ "register shapeNetCore /home/magic/liuchuan/Projects/PointSetGeneration/data/ShapeNetCore.v1", "load model random", "show meshes", "set cameraAngleFromHorizontal 0", ]

Can you tell me how to fix it? Thank you very much!

These errors look like they are due to an OpenGL context being unavailable. This would happen if you are running the code through a remote SSH session. You would need to either run on a machine locally, or set up a server such that you can acquire an OpenGL context from a remote session. Please see issue #4 for more details.
