February 10, 2012 - Oxygen Microscope software version 3.3.4 build 863 is available.
New Oxygen version 3.3 exports allocated diamond cut into DMC file in parametrical mode that further allows modifying and optimising the parameters of cutting in the DiamCalc software: DiamCalc, DiamCalc Cut Designer, DiamCalc Pro and DiamCalc Color. DMC cutting with improved proportions could be imported back into the Oxygen solution. Previous Oxygen versions save allocated diamond cut into DMC in the form of a polyhedron only.
New feature of export / import is especially useful for work with fancy colored cuts.
In the beginning of optimization process, a preliminary solution is allocated in the Oxygen. Then allocated diamond from the Oxygen is passed into the DiamCalc Software for analysing and optimizing its colour.
DiamCalc provides possibility to study reflection and refractive powers of a cut; view the cut in different illuminations (a wider set of possible illuminations than in the Photoreal mode of the Oxygen application); generate light propagation patterns; calculate qualitative properties such as light return, fire, scintillation; simulate cut external appearance within a particular environment like panorama; perform diamond proportion for certain spectrum; etc.
If, in the course of operation with a polished diamond in the DiamCalc software, its optical behavior was improved, then the modified cut saved in the DMC format that can be imported back into its original Oxygen solution. In the Oxygen a final optimization of polished diamond is performed (finding maximum of weight for obtained proportions).
Similarly, optimization can employ authoring cuts generated in DiamCalc CutDesigner.
DMC Export/Import options are available from context menu in a Tree of solutions.
To make export to DMC from context menu:
It is also possible to make export to DMC from main menu File / Export /Diamond to dmc file... (read details in documentation for previous version Oxygen 3.0).
To import DMC file from context menu:
Oxygen 3.3 uses a more precise value of the Diamond Density, 3,51524 g/cm3. It leads to more precise calculation of the weights of polished diamonds. The Density value of 3,522 g/cm3 was used in the previous versions of the software.
Oxygen 3.3 refined methods of calculation of cut parameters. In particular, calculations of Height for of Girdle and Pavilion are updated. The values of parameters can be found in Polish reports, that generate in menu File / Create polish report... A detailed description of modifications in calculations can be found on the page with the Helium Polish 5.4 documentation.
A linked appraiser is an appraiser with ranges for any parameter determined by the values of the parameter from a DMC file from the diamond defined by user.
In the example above the file Name.dmc in the lines DiamondBase and DiamondStart is defined as the base and start diamond, and appraising will be executed with linking to this file.
The Settings / Update active appraiser menu offers two options: By dmc file… and By active diamond.
First option By dmc file... allows to select the necessary dmc file with parameter values known to you. This operation changes the current appraiser and further allocations, and appraising will be done according to this new appraiser.
The behaviour of the lighting control knob was adjusted. Now turning the knob will lead to more smooth and intuitive change of lighting intensity, when looking directly with human eyes. This feature uses non-linear conversion of knob rotation angle to lighting brightness. It is turned on by default.
The new version includes a number of corrections regarding enhanced application reliability in the modules of inclusion withdrawal, search for new directions, and report generation.
