Variables

Public

Name Type Remarks Include Path Unreal Specifiers
bOnlyConnectedToHull bool When protecting negative space, only look for space that is connected out to the convex hull. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=NegativeSpace
  • Meta=(EditCondition="bProtectNegativeSpace")
bProtectNegativeSpace bool Whether to drive decomposition by finding a negative space that should not be covered by convex hulls. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=NegativeSpace
ErrorTolerance float Stop splitting when hulls have error less than this (expressed in cm; will be cubed for volumetric error). Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Decomposition
  • Meta=(ClampMin=0.0, Units=cm, EditCondition="!bProtectNegativeSpace")
MaxGeoToHullVolumeRatioToDecompose float If the geo volume / hull volume ratio is greater than this, do not consider convex decomposition. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Filter
  • Meta=(ClampMin=0.0, ClampMax=1.0)
MaxHullsPerGeometry int32 If greater than zero, maximum number of convex hulls to use in each convex decomposition. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Decomposition
  • Meta=(ClampMin=1)
MinSizeToDecompose float If greater than zero, the minimum geometry size (cube root of volume) to consider for convex decomposition. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Filter
  • Meta=(ClampMin=0.0)
MinThicknessTolerance float Optionally specify a minimum thickness (in cm) for convex parts; parts below this thickness will always be merged away. Overrides NumOutputHulls and ErrorTolerance when needed. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Decomposition
  • Meta=(ClampMin=0.0)
NegativeSpaceMinRadius float Spheres smaller than this are not included in the negative space Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=NegativeSpace
  • Meta=(ClampMin=0, Units=cm, EditCondition="bProtectNegativeSpace")
NegativeSpaceTolerance float Amount of space to leave between convex hulls and protected negative space Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=NegativeSpace
  • Meta=(ClampMin=.01, UIMin=.1, Units=cm, EditCondition="bProtectNegativeSpace")
NumAdditionalSplits int32 Control the search effort spent per convex decomposition: larger values will require more computation but may find better convex decompositions. Dataflow/GeometryCollectionUtilityNodes.h
  • EditAnywhere
  • Category=Decomposition
  • Meta=(ClampMin=0, EditCondition="!bProtectNegativeSpace")
