Constructor & Destructor Documentation

◆ FCutWorkingInfo()

MeshCut::FCutWorkingInfo::FCutWorkingInfo ( FDynamicMesh3 *  WorkingMesh,
double  SnapTolerance 
)
inline

Member Function Documentation

◆ AddSegments()

void MeshCut::FCutWorkingInfo::AddSegments ( const MeshIntersection::FIntersectionsQueryResult &  Intersections,
