Summary

0009164: vtkBoundingBox::GetBound returns incorrect bound.

Description

The use of bit-wise OR in vtkBoundingBox::GetBound(int i) seems to be incorrect. As implemented the maximum bound is always returned, rather than the min or max. I suggest the "(i | 0x1)" should be "(i & 0x1)".

Additional Information

inline double vtkBoundingBox::GetBound(int i) const
{
  // If i is odd then when are returning a part of the max bounds
  // else part of the min bounds is requested. The exact component
  // needed is i /2 (or i right shifted by 1
  return ((i | 0x1) ? this->MaxPnt[i>>1] : this->MinPnt[i>>1]);
}
