Summary0004422: bug about vtkDelaunay2D (sourcecode)
Descriptionint vtkDelaunay2D::RecoverEdge(vtkIdType p1, vtkIdType p2)
{
    ....................................
    ....................................

  // We found initial triangle; begin to track triangles containing edge. Also,
  // the triangle defines the beginning of two "chains" which form a boundary of
  // enclosing triangles around the edge. Create the two chains (from p1 to p2).
  // (The chains are actually defining two polygons on either side of the edge.)
  //
  tris->InsertId(0, cellId);
  rightChain->InsertId(0, p1); rightChainX->InsertPoint(0, p1X);
  leftChain->InsertId(0, p1); leftChainX->InsertPoint(0, p1X);
  if ( signX1 > 0 )
    {
    rightChain->InsertId(1, v1); rightChainX->InsertPoint(1, x1);
    leftChain->InsertId(1, v2); leftChainX->InsertPoint(1, x2);
    }
  else
    {
    leftChain->InsertId(1, v1); leftChainX->InsertPoint(1, x1);
    rightChain->InsertId(1, v2); rightChainX->InsertPoint(1, x2);

    //===================================
    //where the bug :
    //Modify:Now have to exchange the v1 and v2
    int temp = 0;
    temp = v1; v1 = v2; v2 = temp;
    //===================================
    }
  
  // Walk along triangles (edge neighbors) towards point p2.

 Do you have a test case where the current algorithm fails?
