Detailed Description

This class can detect vertices in a face that can be considered useless and then perform the fuse of the edges and remove the useless vertices. By useles vertices, we mean :

  • vertices that have exactly two connex edges
  • the edges connex to the vertex must have exactly the same 2 connex faces .
  • The edges connex to the vertex must have the same geometric support.
