Scanning

Export of *.mme for EOS bruting machines

Export of rough stones with recut solutions in *.mme format for EOS bruting machines is enabled.

While exporting the *.mme file, the user is prompted to specify the girdle interpolation accuracy in mm.

If the table of the rough stone can't be determined reliably, a warning message would pop up during export:

If the table of the rough stone is not parallel to that of the brilliant, another warning message would pop up:

Additional contour disable option

Capturing of additional contours is made optional (enabled by default).
If disabled, the scanning goes on without the additional contours, thus achieving acceleration at the cost of some precision.

Automatic contour clipping control

Scanning is now interrupted automatically if the stone protrudes outside the green frame.

Manual interruption of scanning

Shadow scanning can now be promptly interrupted manually.

Previously the Cancel button only affected the additional contours, and the main contours were scanned anyway. Now the scanning terminates immediately upon pressing Cancel.

Optional automatic discard of photos

An option Delete photos is introduced (disabled by default).
If activated, it enables removal of photos once the contours are built, so as to save the memory. The viewing of problem edges from Model Build Info remains available, but the model and the contours are shown against the black background.

Model building for large stones improved

Model building for large stones having facets with low slopes is improved.

Interface

Clickable fields in Standard report

Fields with maximum/minimum values of certain parameters in the Standard report are made clickable.
Clicking on a field highlights the corresponding facet on the 3D model (either in Model or Photo view mode) so as to reveal the location where the extremal value is reached.

Rotating selected facet to door

Context menu offers the ability to rotate the selected facet to the door. To select a facet, use the clickable fields in the Standard report (see above).

Configurable shortcuts

Shortcuts are made configurable.

Explanatory tooltips

Parameters in MyAppraiser are now accompanied with illustrated definitions which are shown in a tooltip upon demand.

Scanner mode made default

HPOxygen is set to switch to Scanner view mode automatically, if started on a project without model and with hardware available.

Smart Recut

Smart Recut for Oval

Smart Recut with Oval cut as a target is now available.
To use it, perform the following steps:

1. Select the appraiser called MyOvalOpt | MyOval:
   
   
   
2. Run the ordinary Recut with cutting type set to Oval:
   
   
   
3. Select the obtained solution and switch to the algorithm 13. SmartRecut (Brilliant, Oval):
   
   
   If the appraiser doesn't match the cutting type of the starting solution, a warning message will pop up:
   
   
   
4. Click Run. A series of eight solutions will be produced, according to presets.

Smart Recut for Oval relies on its own presets, which have the same overall meaning as those for Brilliant, but use a different set of parameters.

Smart Recut for Oval is currently incompatible with the options of Extra Facet (see below) and Fixed Girdle.

Smart Recut with Extra Facets

SmartRecut with Extra Facets is now available.
To allow the solutions having this feature, check Allow Extra Girdle Facets on the Recut panel before running Smart Recut:

The number of extra facets and their maximum height are introduced as parameters in MyAppraiser.

Smart Recut in multi-diamond solutions

Smart Recut in multi-diamond solutions is improved.

Reports

Label reports

Label report processing is updated. Custom label reports from previous versions of HPOxygen, if any, may be displayed incorrectly.

Precision controls

Standard report is enabled with a precision control that allows producing reports with enhanced precision of up to 3 extra decimal digits.

Label report is also enhanced with a similar control.

Lower Facet Length

Lower Facet Length parameter is added for Cushion cuts.

It is defined as the projected distance from the junction of the main pavilion facets to the corresponding side of the girdle, and reported separately for all four sides.

Miscellaneous

1. Tolerance thresholds (modelEps, girdleEps) are now correctly interpreted during import of models from HP Pacor.
   Usage of non-default values of these thresholds in HP Pacor could lead to different model built from the same contours, as compared to HPOxygen.
2. Inclusion clarity can now be set in HPO.

Bugfixes

1. Memory leaks are fixed and memory consumption improved.
2. HASP messages after the Demo license ends are fixed.

3. Missing values for Cushion cuts (measurements # 3 and 4 for Crown Main Width angle and Crown Main Length angle) are added to the reports.

   

   Reported in	Section	Values	Units	Bookmarks
   Full Report for Cushion	Detailed Parameters	Individual values #3, 4	°	CRN_MAIN_WIDTH_ANGLE_DEG_3, CRN_MAIN_WIDTH_ANGLE_DEG_4, CRN_MAIN_LENGTH_ANGLE_DEG_3, CRN_MAIN_LENGTH_ANGLE_DEG_4

   Note that the average, min, and max values were already calculated correctly, taking into account all four individual measurements. Also, the missing measurements were correctly displayed on the pictures.
4. Erroneous discount for fancy cuts is fixed.
5. Capture of focus upon hovering mouse cursor over a 3D scene is fixed.

6. Bug that prevented the usage of Smart Recut with fixed parts (Fixed Girdle, etc.) is resolved.

   Note that Smart Recut with fixed parts can't be used in multi-diamond solutions.
7. Bug that occasionally prevented SmartRecut from working in multi-diamond solutions is fixed.
8. Erroneous estimation of camera FPS is fixed.
9. Failure to refine models with acute angle between adjacent facets is fixed.
