The Allow Girdle Extra Facets option of the "SmartRecut (Brilliant, Oval)" algorithm allows enlarging the mass of the solutions by producing the extra facets if possible.
Detailed information about GirdleCrownExtraFacets and GirdlePavilionExtraFacets parameters affecting how the Allow Girdle Extra Facets option works, is presented on the Girdle Extra Facets page.
The mechanism of how the girdle extra facets are created is improved. The change is how the position of the extra facet is defined. The improved extra facet positioning function allows getting solutions with the larger mass.
Project: ef_101ct_test.ox2z, profile profile_test.txt. Note Within the project:
|
| Recut | Old Mechanism | New Mechanism | |
|---|---|---|---|
| Mass, ct | 0.9623 | 1.0057 | 1.0110 |
| Front Side |
|
|
No extra facet here. The better extra facet is created on the back side. |
| Back Side |
|
In this example, an old mechanism does not see any potential for the extra facet creation on the back side. |
Extra facet providing more mass increase is created on the back side. |
In HP Oxygen (predecessor of HP Carbon) version 4.8.20 the extra facet option functioning has been improved. The description of the improvement, as well as the general description of the option usage, is presented in the video:
- represents solution obtained manually
- solution obtained by Smart Recut with an old Extra Facet mechanism
- solution obtained by Smart Recut with a new Extra Facet mechanism
The old mechanism produces the extra facet of the lower size on the front side.
The general limitation for number of extra facets will be 1.
