continuityType

Type: Rhino.Geometry.Continuity
Type of continuity to search for.

t0

Type: System.Double
Search begins at t0. If there is a discontinuity at t0, it will be ignored. This makes it possible to repeatedly call GetNextDiscontinuity() and step through the discontinuities.

t1

Type: System.Double
(t0 != t1) If there is a discontinuity at t1 it will be ignored unless continuityType is a locus discontinuity type and t1 is at the start or end of the curve.

t

Type: System.Double
If a discontinuity is found, then t reports the parameter at the discontinuity.

Type: Boolean
Parametric continuity tests c = (C0_continuous, ..., G2_continuous): true if a parametric discontinuity was found strictly between t0 and t1. Note well that all curves are parametrically continuous at the ends of their domains. Locus continuity tests c = (C0_locus_continuous, ...,G2_locus_continuous): true if a locus discontinuity was found strictly between t0 and t1 or at t1 is the at the end of a curve. Note well that all open curves (IsClosed()=false) are locus discontinuous at the ends of their domains. All closed curves (IsClosed()=true) are at least C0_locus_continuous at the ends of their domains.
