BoneTransform struct

#include <Runtime/Animation/Public/AnimTypes.h>

Value-type local or world-space bone transform evaluated by the animation system. Translation/scale use SimFloat (Fixed32 metric precision). Rotation uses SimUnit (FixedUnit precision) for bit-identical results under TNX_DETERMINISM.

Public static functions

static auto Identity() -> BoneTransform

static auto Compose(const BoneTransform& parent, const BoneTransform& child) -> BoneTransform

Apply child transform in the local space of parent (full TRS composition).

static auto NLerp(const BoneTransform& a, const BoneTransform& b, SimFloat t) -> BoneTransform

Normalized linear blend between two transforms by weight [0, 1].

static auto WeightedAdd(const BoneTransform& acc, const BoneTransform& sample, SimFloat w) -> BoneTransform

Accumulate a weighted sample into an existing accumulator. Call Normalize() after all slots.

static auto Normalize(const BoneTransform& acc, SimFloat totalWeight) -> BoneTransform

Normalize an accumulated result produced by one or more WeightedAdd calls.

static auto ApplyAdditive(const BoneTransform& base, const BoneTransform& delta, SimFloat alpha) -> BoneTransform

Apply an additive delta authored from identity: translation adds, rotation composes base * nlerp(id, delta, alpha).
