Function Documentation

delta()

float anim_snapshot::delta ( const AnimSnapshot & a, const AnimSnapshot & b )

inlinenodiscard

PR-27 animation-state delta.

See AnimSnapshot.hpp's file comment for the formula derivation. Returns a dimensionless non-negative scalar — 0 means identical state, larger means more drift between a and b. Typical "accept" threshold: 0.10.

Here is the caller graph for this function:

pack()

void anim_snapshot::pack ( const AnimSlot & s, std::uint8_t out[4] )

inline

Pack one AnimSlot into 4 bytes for wire transmission.

• byte 0 : clipIdRaw (or 0xFF for inactive)
• bytes 1-2 : timeRatio quantised to uint16_t ([0..1] → [0..65535])
• byte 3 : weight quantised to uint8_t ([0..1] → [0..255])
