hi there.
I am just new in java 3d
why my program always says
Exception in thread "main" java.lang.NullPointerException: Canvas3D: null GraphicsConfiguration
at javax.media.j3d.Canvas3D.checkForValidGraphicsConfig(Canvas3D.java:963)
at javax.media.j3d.Canvas3D.<init>(Canvas3D.java:1006)
at pkgnew.New.<init>(New.java:39)
at pkgnew.New.main(New.java:51)
Java Result: 1
however, I already installed j3d and jre. I cannot run and compile my program.
Nothing appears when I tried to run my program.
please heLp.... :(
