FGeometrySet3

[FGeometrySet3](API\Runtime\GeometryCore\FGeometrySet3) stores a set of 3D Points and Polyline curves, and supports spatial queries against these sets.

API > API/Runtime > API/Runtime/GeometryCore

FGeometrySet3 stores a set of 3D Points and Polyline curves, and supports spatial queries against these sets.

Since Points and Curves have no area to hit, hit-tests are done via nearest-point-on-ray.

Name Remarks Include Path Unreal Specifiers

void AddCurve ( int CurveID,
const FPolyline3d& Polyline
)

 Add a polycurve with given CurveID and the give Polyline Spatial/GeometrySet3.h  

void AddPoint ( int PointID,
const FVector3d& Position
)

 Add a point with given PointID at the given Position Spatial/GeometrySet3.h  

bool CollectCurvesNearRay ( const FRay3d& Ray,
TArray< FNearest >& ResultsOut,
TFunction< bool(const FVector3d&, const FVector3d&)> PointWithinToleranceTest
) const

 Like FindNearestCurveToRay, but gives all elements within tolerance, rather than just the closest. Spatial/GeometrySet3.h  

bool CollectPointsNearRay ( const FRay3d& Ray,
TArray< FNearest >& ResultsOut,
TFunction< bool(const FVector3d&, const FVector3d&)> PointWithinToleranceTest
) const

 Like FindNearestPointToRay, but gives all elements within tolerance, rather than just the closest. Spatial/GeometrySet3.h  

bool FindAllCurvesSatisfying ( PredicateType Predicate,
IntContainerType& CurveIDsOut
) const

 Fills CurveIDsOut with IDs of curves that satisfy the given predicate. Spatial/GeometrySet3.h  

bool FindAllPointsSatisfying ( PredicateType Predicate,
IntContainerType& PointIDsOut
) const

 Fills PointIDsOut with point IDs of points that satisfy the given predicate. Spatial/GeometrySet3.h  

bool FindNearestCurveToRay ( const FRay3d& Ray,
FNearest& ResultOut,
TFunction< bool(const FVector3d&, const FVector3d&)> PointWithinToleranceTest
) const

 PointWithinToleranceTest is called in parallel and hence must be thread-safe/re-entrant! Spatial/GeometrySet3.h  

bool FindNearestPointToRay ( const FRay3d& Ray,
FNearest& ResultOut,
TFunction< bool(const FVector3d&, const FVector3d&)> PointWithinToleranceTest
) const

 PointWithinToleranceTest is called in parallel and hence must be thread-safe/re-entrant! Spatial/GeometrySet3.h  

bool ParallelFindAllCurvesSatisfying ( PredicateType Predicate,
IntContainerType& CurveIDsOut
) const

 Like FindAllCurvesSatisfying, but parallel, so predicate must be safe to call in parallel. Spatial/GeometrySet3.h  

bool ParallelFindAllPointsSatisfying ( PredicateType Predicate,
IntContainerType& PointIDsOut
) const

 Like FindAllPointsSatisfying, but parallel, so predicate must be safe to call in parallel. Spatial/GeometrySet3.h  

void RemoveCurve ( int CurveID
)

 Remove a curve with given CurveID. Spatial/GeometrySet3.h  

void RemovePoint ( int PointID
)

 Remove a point with given PointID. Spatial/GeometrySet3.h  

void Reset ( bool bPoints,
bool bCurves
)

   Spatial/GeometrySet3.h  

void UpdateCurve ( int CurveID,
const FPolyline3d& Polyline
)

 Update the Polyline of previously-added CurveID Spatial/GeometrySet3.h  

void UpdatePoint ( int PointID,
const FVector3d& Position
)

 Update the Position of previously-added PointID Spatial/GeometrySet3.h
