Member Function Documentation

◆ FindDistanceBetweenEntries()

float FRBFSolver::FindDistanceBetweenEntries ( const FRBFEntry &  A,
const FRBFEntry &  B,
const FRBFParams &  Params,
ERBFDistanceMethod  OverrideMethod = ERBFDistanceMethod::DefaultMethod 
)
static

Util to find distance between two entries, using provided params

◆ FindTargetNeighbourDistances()

bool FRBFSolver::FindTargetNeighbourDistances ( const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets,
TArray< float > &  NeighbourDists 
)
static

Util to find distance to nearest neighbour target for each target

◆ GetOptimalRadiusForTargets()

float FRBFSolver::GetOptimalRadiusForTargets ( const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets 
)
static

Compute the optimal radius for the given targets. Returns the radius

◆ GetRadiusForTarget()

float FRBFSolver::GetRadiusForTarget ( const FRBFTarget &  Target,
const FRBFParams &  Params 
)
static

Returns the radius for a given target

◆ InitSolver()

TSharedPtr< const FRBFSolverData > FRBFSolver::InitSolver ( const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets 
)
static

Given a set of targets and new input entry, give list of activated targets with weights

◆ IsSolverDataValid()

bool FRBFSolver::IsSolverDataValid ( const FRBFSolverData &  SolverData,
const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets 
)
static

◆ Solve()

void FRBFSolver::Solve ( const FRBFSolverData &  SolverData,
const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets,
const FRBFEntry &  Input,
TArray< FRBFOutputWeight > &  OutputWeights 
)
static

Given a set of targets and new input entry, give list of activated targets with weights

TotalWeight : (Params.bNormalizeWeightsBelowSumOfOne ? 1.f / TotalWeight : 1.f);

◆ ValidateTargets()

bool FRBFSolver::ValidateTargets ( const FRBFParams &  Params,
const TArray< FRBFTarget > &  Targets,
TArray< int > &  InvalidTargets 
)
static

Given a list of targets, verify which ones are valid for solving the RBF setup. This is mostly about removing identical targets which invalidates the interpolative solver. Returns true if all targets are valid.
