[JAVA3D] Color with LineStripArray

[S�nchez Sanz, Javier]

Hi, I'm trying (for a long time) to make a LineStripArray with color, but it
appear black. I'm using a lit scene, so coloring attributes are ignored.
I make a geometry colors and material color, but none of them seems to work.
I have an ambient and a directional light. I put spheres and they are
correctly rendered (with colors).

thanks,

//the code is...

   Point3d puntosRef[] =  {
            new Point3d(2.0d,-1.0d,0.0d),
            new Point3d(0.0d,0.0d,0.0d),
            new Point3d(-1.0d,0.0d,0.0d),
            };

    Point3d coords[]=new Point3d[puntosRef.length];

    int i;
    for (i=0;i<puntosRef.length;i++){
      coords[i]=puntosRef[i];
    }

    Appearance polyAppear = new Appearance();
    Color3f color = new Color3f(0.0f,0.0f,1.0f);
    Material mat = new Material(new
Color3f(0.2f,0.2f,0.2f),_cblack,color,_cwhite,0.5f);
    polyAppear.setMaterial(mat);

    Color3f colores[] = {color,color,color};


    int stripCounts[]={3};
    LineStripArray polylineBase = new LineStripArray (puntosRef.length,

LineStripArray.COORDINATES|LineStripArray.NORMALS|LineStripArray.COLOR_3
              ,stripCounts);
    polylineBase.setCoordinates(0,coords);
    polylineBase.setColors(0,colores);
