  • n/ - Black (those wich it’s top face is Black)

  • g/ - Green (those wich it’s top face is Green)

  • t/ - To extrate (this will be extracted)

  • x/ - Extracted (this was extracted)

#paint(hash_faces, name_file) ⇒ Object

Paints the faces of the tooth image on hash colors based. The tooth’s filename represents the faces painted, The filename’s characters are:

  • w - White

  • g - Green

  • b - Blue

  • n - Black

  • r - Red

  • t - To extract

  • x - Extracted

and are ordered, begining on the upper face of the the tooth and moving clockwise ending on the center face.
