const ON_Brep* ON_PolyEdgeSegment::m_brep

ON_COMPONENT_INDEX ON_PolyEdgeSegment::m_component_index

When the Rhino object is a brep, m_component_index refers to either an edge or a trim.

◆ m_edge

const ON_BrepEdge* ON_PolyEdgeSegment::m_edge

3d edge in m_brep

◆ m_parent_object

const void* ON_PolyEdgeSegment::m_parent_object

Runtime helpers.

When m_component_index refers to an ON_BrepTrim, there are four domains and 4 classes derived from ON_Curve that play a role in the polyedge segment. It is possible for all 4 of these domains to be different.

"this" ON_PolyEdgeSegment is an ON_ProxyCurve. The evaluation domain of "this" is = this->Domain() = ON_ProxyCurve::m_this_domain

ON_ProxyCurve::m_real_curve points to the curve in the c3 = ON_Brep::m_C3[edge.m_c3i]. "this" is a proxy for some sub-interval of c3. = this->ProxyCurveDomain() = ON_ProxyCurve::m_real_curve_domain

The edge, an ON_BrepEdge, is also a proxy based on c3, and the edge's evaluation domain is edge.m_this_domain.
ON_PolyEdgeSegment::m_edge_domain records the increasing subinterval of edge.m_this_domain that corresponds to the portion of c3 "this" is using.

The trim, an ON_BrepTrim, is a proxy based on a curve in ON_Brep::m_C2[]. Some portion of the trim corresponds to the portion of the edge we are using. m_trim_domain is an increasing, possible subinterval, of the trim's domain ON_BrepTrim::m_this_domain. CRhinoBrepObject or CRhinoCurveObject
