[vtk-developers] vtkMath::Dot2D

[David Doria]

Is there any reason:

  // Description:
  // Dot product of two 2-vectors. The third (z) component is
  // ignored (double-precision version).
  static double Dot2D(const double x[3], const double y[3]) {
    return ( x[0] * y[0] + x[1] * y[1] );};

needs to accept 3-vectors and talk about how it ignores the last
component? Couldn't it just be:

  // Description:
  // Dot product of two 2-vectors. (double-precision version).
  static double Dot2D(const double x[2], const double y[2]) {
    return ( x[0] * y[0] + x[1] * y[1] );};

Thanks,

David
