Tree Timing Question

Hello,

I am having a little trouble to understant the timing test. Because when the function timme(insert tree)tree is called what is variable is the maxlevel, but in the output graph the x-axis is called max points per region. Seems Like two differnt variables are being reported.

Thank you,

Rafael

    double TimeOBBTree(vtkPolyData* polydata, int maxLevel, int numberOfTrials,
                 vtkMinimalStandardRandomSequence* rng)
  {
    vtkNew<vtkTimerLog> timer;
    timer->StartTimer();

// Create the tree
vtkNew<vtkOBBTree> obbTree;
obbTree->SetDataSet(polydata);
obbTree->AutomaticOff();
obbTree->SetMaxLevel(maxLevel);
obbTree->BuildLocator();
