[vtkusers] A question about vtkProgrammableSource

[pagen_ivan]

vtkusers:
   Hello, I am trying to translate a 3D reconstruction programme in python to one in c++. When I use vtkProgrammbleSource to get some data for vtkSurfaceReconstructorfilter to reconstruct the surface, I get a message from msvc "vtkSurfaceReconstructionFilter (0x051210C8): No points to reconstruct". So I think there may be some mistake about my usage of setExecuteMethod.  I find the programme have not carried out the function "ReadPoints()" I made. Part of my programme is showed below:


vtkProgrammableSource * PSP=vtkProgrammableSource::New();
void ReadPoints(void * PSPointer)
{
  float  PointsVal[10];
  FILE * fp1;
  PSP=(vtkProgrammableSource *) PSPointer;
  vtkPolyData * OutPut=vtkPolyData::New();
  vtkPoints * Points =vtkPoints::New();
  fp1=fopen("data.txt","r");

  rewind(fp1);
  while(PointsVal[0]!=1000)
  {
    fscanf(fp1,"%f %f %f",PointsVal,PointsVal+1,PointsVal+2);	
    if(PointsVal[0]>1)	break;
    Points->InsertNextPoint(PointsVal[0],PointsVal[1],PointsVal[2]);
   }

   OutPut=PSP->GetPolyDataOutput();
   OutPut->SetPoints(Points);
}										


void main()
{ 
   vtkProgrammableSource * PointSource=vtkProgrammableSource::New();

   PointSource->SetExecuteMethod(ReadPoints, (void *) PointSource);//??????????
   
   vtkSurfaceReconstructionFilter * Surf=vtkSurfaceReconstructionFilter::New();
   Surf->SetInput(PSP->GetPolyDataOutput());
..............................................
.............................................
}

  I have tried a lot, but I still can not get a result, could you kindly help me with this?
  Thanks a lot!!
