| 33 | //! is built from a face or a shell, which bounds it, and with |
| 34 | //! a reference point, which specifies the side of the |
| 35 | //! surface where the matter of the half-space is located. |
| 36 | //! A half-space is a tool commonly used in topological |
| 37 | //! operations to cut another shape. |
| 38 | //! A MakeHalfSpace object provides a framework for: |
| 39 | //! - defining and implementing the construction of a half-space, and |
| 40 | //! - consulting the result. |
