Syntax

struct FSearchIndex : public UE::PoseSearch::FSearchIndexBase

Remarks

A search index for animation poses. The structure of the search index is determined by its UPoseSearchSchema. May represent a single animation (see UPoseSearchSequenceMetaData) or a collection (see UPoseSearchDatabase).

Variables

FKDTree	KDTree
TAlignedArray< float >	Mean
float	PCAExplainedVariance
TAlignedArray< float >	PCAProjectionMatrix
TAlignedArray< float >	PCAValues
TAlignedArray< float >	WeightsSqrt	We store weights square roots to reduce numerical errors when CompareFeatureVectors ((VA - VB) * VW).square().sum() instead of ((VA - VB).square() * VW).sum() since (VA - VB).square() could lead to big numbers, and VW being multiplied by the variance of the dataset
