GeoKernel3D 👾

  GeoKernel3D is a personal C++ experiment exploring the foundation of:  

• 3D Computational Geometry
• Graphics Mathematics
• CAD Kernel Concepts
• B-Rep data structures
• STEP-Based CAD Representations

The goal is to build geometry and topology structures from scratch while gradually working toward STEP file understanding and CAD data processing.

Notes

This is an experimental project.

The focus is on exploration, understanding, and implementation rather than performance, optimization, or production-quality CAD functionality.
