Discussion and group review topics for the Paris Code Sprint 2016.


  • How to get rid of validity test before geometry construction ?
    • add a flag to the postgis geometry ? (is_valid)
  • Is there a way to live with two kernels (inexact and exact) to avoid exact geometry construction when not needed ?
  • Does the new "expanded" object representation offered by postgresql helps in avoiding to serialize / unserialize between each call ?
  • Any advances in CGAL about 3D snap rounding ?
  • Integrate spherical kernels ?

Functions that would be nice to have in SFCGAL

  • alpha shapes from CGAL 2D and 3D
  • "field of view" : not necessarily related to CGAL
  • roof generation from straight skeleton
