Functions

  Type Name Description
Public function Static UFunction BlueprintCallable, Category, Meta void

DownsamplePoints ( const TArray< FVector >& Points,
const FGeometryScriptPointPriorityOptions& Options,
FGeometryScriptIndexList& DownsampledIndices,
int32 KeepNumPoints,
UGeometryScriptDebug* Debug
)

 Find a subset of the given Points of a specified size.
Public function Static UFunction BlueprintCallable, Category, Meta void

FlattenPoints ( const TArray< FVector >& PointsIn3D,
TArray< FVector2D >& PointsIn2D,
const FGeometryScriptPointFlatteningOptions& Options
)

 Convert an array of points from 3D to 2D, by transforming into the given ReferenceFrame and taking the X,Y coordinates Note that to transform into the ReferenceFrame, we apply the inverse of the ReferenceFrame's transform.
Public function Static UFunction BlueprintCallable, Category void

GetPointsFromIndexList ( const TArray< FVector >& AllPoints,
const FGeometryScriptIndexList& Indices,
TArray< FVector >& SelectedPoints
)

 Create an array of the subset of AllPoints indicated by the Indices list
Public function Static UFunction BlueprintCallable, Category, Meta void Use K-Means clustering to cluster the given points into a target number of clusters, and return the clusters as an array of lists of point indices.
Public function Static UFunction BlueprintCallable, Category, Meta void

KMeansClusterToIDs ( const TArray< FVector >& Points,
const FGeometryScriptPointClusteringOptions& Options,
TArray< int32 >& PointClusterIndices
)

 Use K-Means clustering to cluster the given points into a target number of clusters, and return an array with a cluster index per point.
Public function Static UFunction BlueprintCallable, Category void

OffsetTransforms ( UPARAM(ref) TArray< FTransform >& Transforms,
double Offset,
FVector Direction,
EGeometryScriptCoordinateSpace Space
)

 Offset the location of all Transforms by Offset in the given Direction, either locally in the space of the transform or in world space.
Public function Static UFunction BlueprintCallable, Category void

TransformsToPoints ( const TArray< FTransform >& Transforms,
TArray< FVector >& Points
)

 Create an array of the positions of the input Transforms
Public function Static UFunction BlueprintCallable, Category, Meta void

UnflattenPoints ( const TArray< FVector2D >& PointsIn2D,
TArray< FVector >& PointsIn3D,
const FGeometryScriptPointFlatteningOptions& Options,
double Height
)

 Convert an array of points from 2D to 3D, by transforming out of the given ReferenceFrame, with the given Height for the non-flat axis (default Z).
Public function Static Const UFunction BlueprintCallable, Category static Make a Axis Aligned Bounding Box that bounds the given Points, optionally expanded by some additional amount on each side
