Function knotplot()
is useful for production-quality plotting
of knots with crossings indicated; knotplot2()
is more useful
for development.
For knotplot2()
:
rainbow
; use rainbow colouring for the segments
seg
; plot the Bezier nodes and handles. The positions
of the nodes and handles are obtained from an object of class
controlpoints
.
text
; include the segment number on the segment
cross
; label the crossings
ink
; label the nodes with their inkscape numbering
width
; show the bending strain energy
For knotplot()
:
overunderobj
; A two-column matrix indicating the sense
of the crossing. Each row corresponds to a crossing; the first entry
is the segment number of the overstrand, and the second is the
understrand
gap
; the width of the gap
arclength
Gap width measured by arc length or Euclidean
distance
