| 44 | // 2. Modify all faces of the master zone, by putting them into the master |
| 45 | // patch (look for orientation) and their renumbered mirror images |
| 46 | // into the slave patch |
| 47 | // 3. Create a point renumbering list, giving a new point index for original |
| 48 | // points in the face patch |
| 49 | // 4. Grab all faces in cells on the master side and renumber them |
| 50 | // using the point renumbering list. Exclude the ones that belong to |
| 51 | // the master face zone |
| 52 | // |
| 53 | // Note on point creation: |
| 54 | // In order to take into account the issues related to partial |
| 55 | // blocking in an attach/detach mesh modifier, special treatment |
| 56 | // is required for the duplication of points on the edge of the |
| 57 | // face zone. Points which are shared only by internal edges need |
| 58 | // not to be duplicated, as this would propagate the discontinuity |
| 59 | // in the mesh beyond the face zone. Therefore, before creating |
| 60 | // the new points, check the external edge loop. For each edge |
| 61 | // check if the edge is internal (i.e. does not belong to a |
| 62 | // patch); if so, exclude both of its points from duplication. |
