Predictive Model Concept and Pipeline
OctoNus Finland Oy Ltd, Tampere, Finland
March – October 2023
Overview
In the diamond production workflow, manufacturers rely on scan and virtual models at every technological stage. The preplan concept acts as a predictive virtual model anticipating outcomes for each step and enabling smooth data transfer across stages.
Collaboration with clients and the company founder led to developing a process architecture, pipeline, and algorithms for crafting virtual 3D models in C++. A Qt-based UI allows configuration of preplan parameters, while data is exported to web reports via HTML, CSS, and JavaScript.
Implemented stages include Blocking – initial shaping of crown & pavilion facets – and Sawing, simulating raw stone division. Each pipeline stage underwent rigorous precision and stability testing.
