Name	Type	Remarks	Include Path
bPostSimplify	bool	If true, output convex hull is simplified down to MaxTargetFaceCount	Operations/MeshConvexHull.h
ConvexHull	FDynamicMesh3	Output convex hull	Operations/MeshConvexHull.h
MaxTargetFaceCount	int32	Target triangle count of the output Convex Hull	Operations/MeshConvexHull.h

static FVector3i DebugGetCellIndex ( const FDynamicMesh3& Mesh, int GridResolutionMaxAxis, int VertexIndex )	Used for testing/debugging	Operations/MeshConvexHull.h
static void GridSample ( const FDynamicMesh3& Mesh, int GridResolutionMaxAxis, TArray< int32 >& OutSamples )	Choose a more or less evenly-spaced subset of mesh vertices.	Operations/MeshConvexHull.h
