hi.. David Gobbi..

The right answer does not know...


code...............

vtkImageData *m_pImageData = m_pVolumeRayCastMapper->GetInput();

 vtkUnsignedShortArray *array = vtkUnsignedShortArray::New();

 //vtkImagedata sampling
 array = (vtkUnsignedShortArray*)m_pImageData->GetPointData()->GetScalars();

 //change of array data, and setting m_pImageData
 float tuple;
 int kOffset=0, jOffset=0, offset=0;
 for(int a = 0; a < ; a++);
 {
      kOffset = bb[a].z*128*128;
      jOffset = bb[a].y*128;
      offset = bb[a].x +jOffset + kOffset;
      array->SetTuple1(offset,0);
 }
