I am using LineArray to do what u need. but it will work with any other Geometry. I
make a LineArray with maximum coordinates I would need. and then keep setting the
coordinates at run time. And it works pretty smooth;
private static final int MaxPoints = 200;
private int m_nLine = -1;
private Shape3D m_shape;
void createShape ()
{
LineArray line = new LineArray(MaxPoints*2, GeometryArray.COORDINATES
);
line.setCapability(line.ALLOW_COORDINATE_READ);
line.setCapability(line.ALLOW_COORDINATE_WRITE);
m_shape = new Shape3D( line, app );
m_shape.setCapability( Shape3D.ALLOW_GEOMETRY_READ );
m_shape.setCapability( Shape3D.ALLOW_GEOMETRY_WRITE );
this.addChild( m_shape );
}
void addPoint (Point3f p3)
{
LineArray line = (LineArray)m_shape.getGeometry();
line.setCoordinate( ++m_nLine, p3 ); }
}

p.s. I m just sending u part of my code so u might have to debug it or if something is
missing tell me

draw an increasing line that needs to update its geometry everytime the
thread executes. Can someone help in this field?
