Variables

  Type Name Description
Protected variable bool bFailed  
Public variable bool bGeometryVolumeUnreliable  
Protected variable bool bIsCompact  
Public variable bool bMustMerge Flag indicating the hull should be merged into another part during a MergeBest() call.
Public variable FAxisAlignedBox3d Bounds  
Public variable FVector3d GeoCenter  
Public variable double GeoVolume  
Public variable double HullError Approximate value indicating how badly the hull mismatches the input geometry.
Public variable TArray< FPlane3d > HullPlanes  
Public variable TArray< FIndex3i > HullTriangles  
Public variable double HullVolume Measurements of the geo and hull, to be used when evaluating potential further splits.
Public variable FDynamicMesh3 InternalGeo Underlying geometry represented by the convex part Note: If IsCompact(), this will only store vertices
Public variable double SumHullsVolume  

Constructors

  Type Name Description
Public function    
Public function  

FConvexPart ( bool bIsCompact
)
