#Discretizes the edge and returns a list of points.
|
|
#The function accepts keywords as argument:
|
|
#discretize(Number=n) => gives a list of 'n' equidistant points
|
|
#discretize(QuasiNumber=n) => gives a list of 'n' quasi equidistant points (is faster than the method above)
|
|
#discretize(Distance=d) => gives a list of equidistant points with distance 'd'
|
|
#discretize(Deflection=d) => gives a list of points with a maximum deflection 'd' to the edge
|
|
#discretize(QuasiDeflection=d) => gives a list of points with a maximum deflection 'd' to the edge (faster)
|
|
#discretize(Angular=a,Curvature=c,[Minimum=m]) => gives a list of points with an angular deflection of 'a'
|
|
#and a curvature deflection of 'c'. Optionally a minimum number of points
|
|
#can be set which by default is set to 2. </pre>
