v0.0.1

0.0.1 (2026-10-24)

The first release: skeletal animation from import to the skinned
vertex, with the same results on every platform, compiler and SIMD
backend, and no allocation at run time.

Added

• Skeletons, poses in local and model space composed as glTF composes
  nodes, and the polar decomposition of model matrices.
• Clips on a uniform grid sampled at the same cost at any time, with
  float and discrete tracks, events and sync markers; a forward cursor
  with the same results, in a faster form and a compact one.
• Clip compression within an error measured on a shell around each
  bone, close to ACL's sizes at a third of its error.
• Blending with per-bone masks, pose differences and additive layers
  and clips, and root motion taken out at build and read as moves
  across any number of loops, forward or backward.
• Animation graphs: clip, blend, mask, additive, select, time scale
  and seek nodes; 1D, triangulated and banded blend spaces; state
  machines with conditions on parameters, time, a clip's phase, end or
  events; one-shots; inertialization and dead blending; sync groups by
  phase or markers; subgraphs; a JSON form; saved and restored
  instances; node inspection for debuggers; evaluation of a subset of
  bones.
• Motion matching: motion databases with weighted feature channels, an
  exact pruned search, a trajectory predictor and a graph node;
  learned motion matching with a model format, a graph node and an
  in-library trainer whose results are the same on every platform and
  with any number of threads.
• Inverse kinematics: two-bone, aim and look-at over a chain, CCD and
  FABRIK chains with cone, twist and hinge limits, full-body XPBD and
  SDLS solvers, a turn limit node, each also a graph node.
• Spring bones as VRMC_springBone 1.0 defines them, with its extended
  colliders and limits, the same motion at any frame rate.
• Ragdoll profiles mapping bones to a physics engine's bodies and
  joints, bodies and motor targets from poses, poses from bodies, and
  get-up placement; a pose input for graphs.
• Retargeting between skeletons with different names, chain lengths,
  rests and proportions, and mirroring on rigs whose sides do not have
  mirrored axes, for poses, baked clips, graphs and motion databases;
  JSON forms for both maps.
• Skinning: skins, palettes, linear, dual quaternion and blended
  skinning and centers of rotation over one influence format, as jobs
  over strided vertex streams; morph targets with in-betweens.
• glTF 2.0 import (JSON and GLB, EXT_meshopt_compression,
  KHR_meshopt_compression, KHR_draco_mesh_compression,
  KHR_animation_pointer, VRMC_springBone and the OMI_physics_*
  extensions) and FBX import (binary and ASCII, versions 3000 to 7700):
  skeletons, skins, influences, morph targets and clips.
• Validation of every file, JSON text and saved state as it is opened,
  in every build: bad data is refused with a status and the offset of
  the first wrong byte, and counts no misuse on the builder; a misuse
  count reports only calls a correct program never makes.
• A CPU check for the AVX2 build, a portable scalar build with the same
  results, a CMake package and a pkg-config module.
• Support for Linux on x86-64 and arm64, macOS, Windows with
  clang-cl, and WebAssembly.
