Your Surface is not always flat
In this video, I explain the difference between a surface that looks flat and a surface that is actually planar.
This matters a lot when you work with fabrication, paneling, facades, fashion, or any workflow where geometry needs to be cut, unfolded, or built accurately.
The main idea is simple:
  • Planar means the surface sits on one single plane
  • A tilted surface can still be planar
  • A surface can look flat but still fail the planarity test
  • Triangulation can break curved surfaces into planar pieces
  • More divisions can give a closer approximation of the original shape
