Scanning

Speed up

Scanning is speeded up. This is especially noticeable at scan modes that require many additional contours. Below are the averaged scan times for two stones. The measurements were made on HP 17D with HP-1 board. Acceleration line in HPODrivers.ini was turned off.

Edge adjustment

Two modes of edge addition during manual adjustment of the model are now working as expected.

The users are advised to choose one of the modes depending on their confidence in the position of the missing edge.
The program, in turn, uses the degree of reliability to determine the extent to which the added edge can be altered during the refinement:

Add edges with high precision produces an edge located as close as possible to the user's input;
Add edges with low precision treats the user's input as a vague hint, so the resulting refined edge may appear some distance away.

Before refinement	After refinement (high precision)		After refinement (low precision)

Note the light-green added edge.	Note the refined model (cyan contours) laid over the original model (dark-green contours with light-green added edge).

Model used: Add_edge_hard_soft.oxgz .

Note that in both cases the refinement still can affect multiple other edges, not necessarily limited to the affected facet.

Interface

Appraiser title is made visible in a tooltip upon hovering the mouse cursor over the list of solutions.

Previously there was no way to know the appraiser when opening an old file with recut solutions.
Shortcuts configuration window would not allow to assign a shortcut which is already assigned to another command.

Reports

Settings for automatic actions now include the selection of label report template.

HPOxygen Public Documentation > 2017-04-24 - HPOxygen Server 3.22.14 > image2017-4-20 15:4:8.png

Previously the option of using custom label report templates was limited to manual generation of the label report via the right panel, and did not extend to automatic actions.

Recut

Step size control is added to the Parameters panel (unlocked mode).

HPOxygen Public Documentation > 2017-04-24 - HPOxygen Server 3.22.14 > image2017-4-21 15:9:54.png

The control has five positions corresponding to the following step sizes:

Position	Step size
Position	Angles	mm	%	Ratio
1 (fine)	0.1	0.01	0.1	0.001
2	0.5	0.05	0.5	0.005
3	2	0.2	2	0.02
4	5	0.5	5	0.05
5 (rough)	10	1	10	0.1

To view the parameter panel, run Recut, select any solution, and click View → Show parameters panel.

Unlocking the Parameters panel is not recommended. Once the parameters have been changed manually, it is no longer guaranteed that the solution fits inside the existing stone.

Bugfixes

Memory leaking issue is fixed.
Bug that led to doubling of Reflect contours during recalculation is fixed.
Incorrect model rendering over photos and contours (shift and scaling) is fixed.
Highlighting of facets for selection of minimum and maximum Crown height and Pavilion height in the Standard Report is temporarily switched off.
Bug that occasionally caused recut solutions of the Semicut (final) algorithm to turn upside down is fixed.
