Description: Use BezierCurve() to get the bezier to intersect.

Member Data Documentation

m_b2w

ON_Xform CRhinoIntSnapCandidate::m_b2w

This transform maps the bezier into world coordinates. For "oridinary" objects it is the identity. For instance references, the bezier is instance definition geometry and m_b2w maps it to the referenced location in world space.

m_bCheckVisibility

bool CRhinoIntSnapCandidate::m_bCheckVisibility

18 Sept 2014, Mikko: If true osnap will only snap to this candidate if the snap location is visible and not covered by shaded objects.

m_bez

ON_BezierCurve CRhinoIntSnapCandidate::m_bez

Use for "phantom" smart-tracking lines.

m_case

int CRhinoIntSnapCandidate::m_case

m_cd

const class CRhCurveDisplay* CRhinoIntSnapCandidate::m_cd

Curve display bezier list to intersect.

The portion of the curve that will be used to look for intersection snaps is either a bezier segment in m_cd or m_bez. Use the BezierCurve() function to get the right one.

m_cd_seg_index

int CRhinoIntSnapCandidate::m_cd_seg_index

seed index for finding the real intersection

m_event

CRhinoSnapEvent CRhinoIntSnapCandidate::m_event

m_near_snap_xform

ON_Xform CRhinoIntSnapCandidate::m_near_snap_xform

This transforms the bezier into snapping coordinates.

m_parallel_point_index

int CRhinoIntSnapCandidate::m_parallel_point_index

index to possible associated smart point parallel lines come from. <0 if not set

m_smart_point_index

int CRhinoIntSnapCandidate::m_smart_point_index

2 Oct 2003, Mikko added a setting that tells which smart point the candidate belongs to if any.

m_tanline

ON_Line CRhinoIntSnapCandidate::m_tanline

7 Oct 2003, Mikko added near point tangent vector. If 2 lines overlap and third line intersects them, it's hard to snap to the intersection because Rhino tends to find the overlapping lines as the 2 closest candidates. Adding a tangent line to help sort out those cases.

m_type

int CRhinoIntSnapCandidate::m_type

4 Oct 2003, Mikko added a setting that tells the inferred line type. 0=notset 1=ortho 2=tan 4=perp 8=tan_parallel 16=perp_parallel can be a combination of the types
