Probe points are in the form:

\[ \mathbf{x}_P = \mathbf{x}_G + t \mathbf{n} \]

where \( \mathbf{x}_G \) is the ghost point and \( \mathbf{n} \) is the direction toward the boundary point. This routine finds an appropriate value for \( t \) such as:

\[ \mathbf{x}_G\mathbf{x}_B < \mathbf{x}_G\mathbf{x}_P \le 2\mathbf{x}_G\mathbf{x}_B \]

The following members of the ib_metrics argument are set:
