[vtkusers] volume rendering from the book, help me!!

["한종철"]

I' m doing a simple example for volume rendering using c++ based on SDI.
But it doesn't work!!
What's the problem??

Please help me!!

What's the problem???
This is my simple source code.


 if(pvtkStructuredPointsReader)
  {
   
    this->opacityTransferFunction->AddPoint(2.0,0.0);
       this->opacityTransferFunction->AddPoint(255,0.2);
       this->colorTransferFunction->AddRGBPoint(0.0, 0.0, 0.0, 0.0);
    this->colorTransferFunction->AddRGBPoint(64.0,1.0,0.0,0.0);
    this->colorTransferFunction->AddRGBPoint(128.0,0.0,0.0,1.0);
    this->colorTransferFunction->AddRGBPoint(192.0,0.0,1.0,0.0);
    this->colorTransferFunction->AddRGBPoint(255.0,0.0,0.2,0.0);
    this->volumeProperty->SetColor(colorTransferFunction);
    this->volumeProperty->SetScalarOpacity(opacityTransferFunction);
   
    this->volumeMapper -> SetVolumeRayCastFunction(compositeFunction);
     this->volumeMapper -> SetInputConnection(this->pvtkStructuredPointsReader->GetOutputPort());
   
   
    this->volume->SetMapper(volumeMapper);
    this->volume->SetProperty(volumeProperty);
  
    pcvtkSDIView->GetRenderer()->SetBackground(0,0,0);
          pcvtkSDIView->GetRenderer()->AddVolume(this->volume);
          pcvtkSDIView->GetRenderer()->ResetCamera();
          pvtkStructuredPointsReader->Delete();
          pvtkStructuredPointsReader = NULL;
  }
