Hi guys

I'm trying to get into Java3D by implementing <http://www.java3d.org/starting.html>, to start with:

import com.sun.j3d.utils.geometry.*;
import com.sun.j3d.utils.universe.*;
import javax.media.j3d.*;

public class Hello3D
{
        public Hello3D()
        {
                SimpleUniverse universe = new SimpleUniverse();
                BranchGroup group = new BranchGroup();
                group.addChild(new ColorCube(0.3));
                universe.getViewingPlatform().setNominalViewingTransform();
                universe.addBranchGraph(group);
        }

        public static void main( String[] args )
        {
                System.setProperty("sun.awt.noerasebackground", "true");
                new Hello3D();
        }
}

I added j3dcore.jar, j3dutils.jar, and vecmath.jar from /deployment/java3d/1.6.0-final/jogamp-java3d.7z to my project. Furthermore I added jog-all, gluegen-rt and gluegen-rt-natives-macosx-universal from /deployment/jogamp-current/jar.

I am using a MacBook Pro 64bit with MacOS 10.15.5 Catalina and IntelliJ IDEA.

When I run main, I get this exception:

What am I doing wrong?


By the way: I couldn't use the jars "jogl-all.jar", "gluegen-rt.jar", and "gluegen-rt-natives-macosx-universal.jar" as project libraries, because then I got those build exceptions:

Error:java: error reading /Users/Denis/Documents/Java/Workspace/Sandbox 3D/lib/jogl-all.jar; error in opening zip file
Error:java: error reading /Users/Denis/Documents/Java/Workspace/Sandbox 3D/lib/gluegen-rt.jar; error in opening zip file
Error:(1, 1) java: cannot access unnamed package
  Error reading file /Users/Denis/Documents/Java/Workspace/Sandbox 3D/lib/jogl-all.jar: error in opening zip file

I had to extract the contents of the jars and add them as folders to the project library.


Many thanx & best regards
