Gemstone cut analysis

A system for reproducing targeted virtual facets in a real gemstone, comprising:

• a processor;
• and
• a memory with instructions that, when executed by the processor, cause the processor to perform steps comprising:
• obtaining data relating to a scanned gemstone;
• generating, using the obtained scanned gemstone data, a 3D gemstone model;
• determining a virtual facet pattern and first exit beam data from a ray trace or beam trace analysis of the 3D gemstone model and an input viewing direction;
• assigning a color to each virtual facet of the 3D gemstone model based on a recorded angle of an exit beam from the first exit beam data relative to a horizon of the 3D gemstone model;
• and
• causing display of the determined virtual facet pattern on a user interface showing the 3D gemstone model, the assigned color, and the determined virtual facet pattern.

A computer-implemented method for generating virtual facet models of a gemstone, the method comprising:

• receiving data regarding a scanned gemstone;
• generating, using the received scanned gemstone data, a 3D gemstone model;
• determining a virtual facet pattern and first exit beam data from a ray trace or beam trace analysis of the 3D gemstone model and an input viewing direction;
• assigning a color to each virtual facet of the 3D gemstone model based on a recorded angle of an exit beam from the first exit beam data relative to a horizon of the 3D gemstone model;
• and
• causing display of the determined virtual facet pattern and virtual facet elaborations on a user interface showing the 3D gemstone model, the assigned color, and the determined virtual facet pattern.
