Syntax

static void BlendFromIdentityAndAccumulate
(
    FTransform & FinalAtom,
    FTransform & SourceAtom,
    float BlendWeight
)

Remarks

Blends the Identity transform with a weighted source transform and accumulates that into a destination transform

SourceAtom = Blend(Identity, SourceAtom, BlendWeight) FinalAtom.Rotation = SourceAtom.Rotation * FinalAtom.Rotation FinalAtom.Translation += SourceAtom.Translation FinalAtom.Scale3D *= SourceAtom.Scale3D

Parameters

Parameter	Description
FinalAtom	[in/out] The atom to accumulate the blended source atom into
SourceAtom	The target transformation (used when BlendWeight = 1); this is modified during the process
BlendWeight	The blend weight between Identity and SourceAtom
