Please find the below actor coding

Thanks for your kind effort
    vtkLODActor boneActor = new vtkLODActor();
                //vtkActor boneActor = new vtkActor();
                boneActor.SetNumberOfCloudPoints(500000);
                boneActor.SetMapper(geobonemapper);
                boneActor.GetProperty().SetColor(0.75,0.5,0.75);
                boneActor.GetProperty().SetAmbientColor(.75, .10, .25);
                boneActor.GetProperty().SetDiffuseColor(0.75, .04, .025);
                boneActor.GetProperty().BackfaceCullingOn();
                boneActor.GetProperty().EdgeVisibilityOn();
                boneActor.GetProperty().FrontfaceCullingOn();
                boneActor.GetProperty().GlobalWarningDisplayOn();
               
boneActor.GetProperty().SetColor(boneActor.GetProperty().GetColor());
                boneActor.GetProperty().SetOpacity(0.75);
                boneActor.GetProperty().SetSpecularPower(100);
                boneActor.GetProperty().SetDiffuse(0.75);
                boneActor.GetProperty().SetSpecular(.4)
