CurveGetNextDiscontinuity Method
Searches for a derivative, tangent, or curvature discontinuity.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: 5.1.50000.0 (5.0.20693.0)
Syntax
public bool GetNextDiscontinuity(
	Continuity continuityType,
	double t0,
	double t1,
	out double t
)

Parameters

continuityType
Type: Rhino.GeometryContinuity
Type of continuity to search for.
t0
Type: SystemDouble
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: SystemDouble
(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: SystemDouble
If a discontinuity is found, then t reports the parameter at the discontinuity.

Return Value

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.
