pyrw.RWdomain module

class pyrw.RWdomain.domain(RW, typ='poly')

Domain class for defining random walk domain.

Parameters:
  • RW (pyrw.RWRW) – A pyrw RW.
  • typ (str) – Type of domain
addArc(vstart, vcenter=None, vend=None, angle=None)

Adds arc from vstart to vend around vcenter to domain.

Parameters:
