Method Description (overview of Connolly)

• Neighbor identification by cubing
  
  
• Identification of contact triplets i < j < k
  
  
• Calculation of probe pos. and vertex coords (Pijk, Vi, Vj, Vk)
  
  
• Calculation of start & stop pos for each pair i, j (p, p')
  
  
• Description of spherical triang., and saddle faces (Vi, Vi', Vj, Vj'), & smooth boundaries
  
  
• Description of contact portions (cut-off from VW)
  
  
• Area calculation of the three types of faces (Connolly's formulas)
