Parts Files

Parts (*.parts) files Description of the boundaries connecting points. Points are indexed from zero. They can be open_boundary /closed_boundary smooth/jagged
For instance: 
part "Chin" {
    indices(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14)
    form open_boundary
         jagged
         point_density 1
}

part "L.Eyebrow" {
    indices(15,16,17,18,19,20)
    form closed_boundary
         jagged
         point_density 1
}
Note: The point_density parameter is generally ignored now.
