double X[3], Y[3], Z[3];

vtkSTLReader *read = vtkSTLReader::New();

 

..................

 

tkPolyData *Source=read->GetOutput();

// Put source points in SourcePoints

SourcePoints = Source->GetPoints();

// For each cell i do:

for (i = 0; i < ncells; i++) 

// Get the points belonging to this cell.

Source->GetCellPoints(i,cells);

 

pId = cells->GetId(0);

SourcePoints->GetPoint(pId,X);

pId = cells->GetId(1);

SourcePoints->GetPoint(pId,Y);

pId = cells->GetId(2);

SourcePoints->GetPoint(pId,Z);
