Description: This function can be used to detect intersection events that are "nearly" points. Parameters: tiny_tolerance - [in] Returns: True if m_type is ssx_transverse_point or ssx_tangent_point, or, m_type is ssx_transverse, ssx_tangent or ssx_overlap and length of the longest side of m_curve3d's bounding box is <= tiny_tolerance.

Description: Check intersection event values to make sure they are valid. Parameters: text_log - [in] If not null and an error is found, then a description of the error is printed to text_log. intersection_tolerance - [in] 0.0 or value used in intersection calculation. overlap_tolerance - [in] 0.0 or value used in intersection calculation. fitting_tolerance - [in] 0.0 or value used in intersection calculation. surfaceA - [in] nullptr or surfaceA passed to intersection calculation. surfaceA_domain0 - [in] nullptr or surfaceA "u" domain used in intersection calculation. surfaceA_domain1 - [in] nullptr or surfaceA "v" domain used in intersection calculation. surfaceB - [in] nullptr or surfaceB passed to intersection calculation. surfaceB_domain0 - [in] nullptr or surfaceB "u" domain used in intersection calculation. surfaceB_domain1 - [in] nullptr or surfaceB "v" domain used in intersection calculation. Returns: True if event is valid.

ON_Curve* ON_SSX_EVENT::m_curveA |
2d surface A parameter space curve
If m_type = ssx_transverse, ssx_tangent, or ssx_overlap, then the intersection curves are returned here.
In all cases the 3 curves are compatibly oriented. For ssx_transverse events, the 3d curve direction agrees with SurfaceNormalB x SurfaceNormalA For ssx_tangent events, the orientation is random. For ssx_overlap events, the overlap is to the left of m_curveA. These curves are deleted by ~ON_SSX_EVENT(). If you want to harvest a curve for long term use, set the pointer to nullptr.

This field is a scratch field for users. The constructor sets it to zero and the intersectors never use it.
