static FSimplicial * NewSimplicial ( const Chaos::FParticles& Vertices,
const Chaos::FTriangleMesh& TriMesh,
const Chaos::FImplicitObject* Implicit,
const int32 CollisionParticlesMaxInput
)

 Culls particles inside Implicit_, and coincident particles (defined by being within 1/20'th of the size of the domain from one another), truncates at CollisionParticlesMaxInput_, and returns a bounding volume hierarchy of the remainder. GeometryCollection/GeometryCollectionCollisionStructureManager.h  

static FSimplicial * NewSimplicial ( const Chaos::FParticles& AllParticles,
const TManagedArray< int32 >& BoneMap,
const ECollisionTypeEnum CollisionType,
Chaos::FTriangleMesh& TriMesh,
const float CollisionParticlesFraction
)

 Culls particles by importance (See `FTriangleMesh::GetVertexImportanceOrdering()_), and returns a bounding volume hierarchy of the remainder. GeometryCollection/GeometryCollectionCollisionStructureManager.h  

static void UpdateImplicitFlags ( FImplicit* Implicit,
const ECollisionTypeEnum CollisionType
)

 Calls SetDoCollide(false)_ and SetConvex(false) on Implicit_ if CollisionType is `ECollisionTypeEnum::Chaos_Surface_Volumetric_. GeometryCollection/GeometryCollectionCollisionStructureManager.h
