Latest Changes and Upgrades
From version 1.0.2 - Mechanism Improvement
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.
|Recut||Old Mechanism||New Mechanism|
The old mechanism produces the extra facet of the lower size on the front side.
No extra facet here. The better extra facet is created on the back side.
The general limitation for number of extra facets will be 1.
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.
