ChFiDS_Spine Class Reference

Contient les informations necessaires a la
construction d un conge volumique :

• ligne guide composee d'edges du solide, tangents
  entre eux, et bordes par des faces tangentes entre
  elles.
  
  Les outils de construction du Sp
  par propagation a partir d un edge du solide sont
  fournis dans le Builder de Fil3d.
  
  Le Spine contient par aileurs des
  informations concernant la nature des extremites
  du conge ( sur bord libre, sur cassure ou ferme ).
  
  REMARQUE IMPORTANTE : la ligne guide ainsi
  representee n est pas C2, alors que le cheminement
  le reclame. Un certain nombre d amenagements
  paliatifs (voir les methodes en fin) sont prevus,
  s ils sont insuffisants il faudra changer notre
  fusil d epaule et doubler le Spine d
  une ligne C2 avec les consequences que l on sait
  pour gerer les va et vient entre KPart Blend dans
  Fil3d.
