bool AddNegativeSpace ( const TFastWindingTree< FDynamicMesh3 >& Spatial,
const FNegativeSpaceSampleSettings& Settings
)

 Note: This version of AddNegativeSpace assumed the input had flipped triangle orientations CompGeom/ConvexDecomposition3.h  

bool AddNegativeSpace ( const TFastWindingTree< FDynamicMesh3 >& Spatial,
const FNegativeSpaceSampleSettings& Settings,
bool bHasFlippedTriangles
)

 Add spheres covering the negative space of the given fast winding tree CompGeom/ConvexDecomposition3.h  

void AddSphere ( FVector3d InCenter,
double InRadius
)

   CompGeom/ConvexDecomposition3.h  

void Append ( const FSphereCovering& Other
)

   CompGeom/ConvexDecomposition3.h  

void AppendSpheres ( TArrayView< const UE::Math::TSphere< double > > Spheres
)

   CompGeom/ConvexDecomposition3.h  

void AppendTransformed ( const FSphereCovering& Other,
const FTransform& Transform
)

 Append spheres from Other w/ the given Transform Note: Non-uniform scales will scale the radius by the smallest scale axis's magnitude (matching how physics collision transforms spheres) CompGeom/ConvexDecomposition3.h  

void ApplyTransform ( const FTransform& Transform
)

 Apply transform to spheres Note: Non-uniform scales will scale the radius by the smallest scale axis's magnitude (matching how physics collision transforms spheres) CompGeom/ConvexDecomposition3.h
