Optional tolerances for angle and curvature can be provided. The 't' parameter receives the parameter value of the found discontinuity. Returns true if a discontinuity is found, false otherwise.

```API Description
Description: Searches for a derivative, tangent, or curvature discontinuity.
Parameters:
  direction: If 0, then "u" parameter is checked. If 1, then the "v" parameter is checked.
  continuityType: The desired continuity.
  t0: 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: (t0 != t1) If there is a discontinuity at t1 is will be ignored unless c is a locus discontinuity type and t1 is at the start or end of the curve.
  cosAngleTolerance: default = cos(1 degree) Used only when continuityType is G1_continuous or G2_continuous. If the cosine of the angle between two tangent vectors is <= cos_angle_tolerance, then a G1 discontinuity is reported.
  curvatureTolerance: (default = ON_SQRT_EPSILON) Used only when continuityType is G2_continuous. If K0 and K1 are curvatures evaluated from above and below and |K0 - K1| > curvature_tolerance, then a curvature discontinuity is reported.
  t: if a discontinuity is found, then t reports the parameter at the discontinuity.
Returns:
  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.
```

### Checking Point Inclusion in RhinoCommon Brep (C#)

Source: https://github.com/oleynikaleksandr/rhinocommon-api/blob/main/rhinocommon-docs-md/Rhino.Geometry.Brep.md

Determines if a 3D point is inside a closed, manifold Brep. It works by intersecting a line through the point with the Brep and analyzing the closest intersection point and face normal. Requires a tolerance value and can check for strict inclusion. Note: Does not validate if the Brep is closed or manifold, so results are only valid for such Breps.

```C#
bool IsPointInside(Point3d point, double tolerance, bool strictlyIn)
```
