Bill
very kind to your reply. 


i have included that too, to set scalar visibility in off. even i dint get the result, am wondering where i made mistake.
if time permits you please have a look on below code

Thanks
Guru

    //for skin and bone Diagram
            //For setting Bone Colour
                vtkGeometryFilter  geovolumebone = new vtkGeometryFilter();
                geovolumebone.SetInput(polyReader.GetOutput());
                vtkPolyDataMapper  geobonemapper = new vtkPolyDataMapper();
                geobonemapper.SetInput(geovolumebone.GetOutput());
                geobonemapper.ScalarVisibilityOff();
                //vtkActor boneActor = new vtkActor();
                vtkLODActor boneActor = new vtkLODActor();
                boneActor.SetNumberOfCloudPoints(100000);
                boneActor.SetMapper(geobonemapper);
                //boneActor.GetProperty().SetColor(1, 0.4782, 0.2546);
                boneActor.GetProperty().SetColor(1, 0, 0);
                //boneActor.GetProperty().SetDiffuseColor(1, 1, .9412);
                boneActor.GetProperty().SetSpecularPower(100);
                boneActor.GetProperty().SetOpacity(1.5);
                boneActor.GetProperty().SetDiffuse(1.75);
                boneActor.GetProperty().SetSpecular(1.75);
                //For setting Bone Colour
       
            //For setting Skin Colour
                vtkMarchingCubes skin = new vtkMarchingCubes();
                skin.SetInput(dicomreader.GetOutput());
                skin.SetValue(0, -300);
                skin.ComputeNormalsOn();
//               
                vtkGeometryFilter geovolumeSkin = new vtkGeometryFilter();
                geovolumeSkin.SetInput(contour.GetOutput());
//               
                vtkPolyDataMapper skinmapper = new vtkPolyDataMapper();
                skinmapper.SetInput(geovolumeSkin.GetOutput());
                skinmapper.ScalarVisibilityOff();
               
           
                vtkLODActor actorskin = new vtkLODActor();
                actorskin.SetNumberOfCloudPoints(100000);
                actorskin.SetMapper(skinmapper);
                //actorskin.GetProperty().SetColor(1, 0.547237, 0.319073);
                actorskin.GetProperty().SetColor(0.94,0.58, 0.17);
                actorskin.GetProperty().SetSpecularPower(100);
                actorskin.GetProperty().SetOpacity( 3.3 );
