Detailed Description

This BVH implementation is based on the source code implementation from the book "Physically Based Rendering" (v2 and v3)

Adaptions performed:

  • Types and class types adapted to KiCad project
  • Convert some source to build in the C++ specification of KiCad
  • Code style to match KiCad
  • Asserts converted
  • Use compare functions/structures for std::partition and std::nth_element
