Crate mmd_anim_runtime 

Renderer-independent MMD animation runtime core.

The core crate intentionally has no Wasm, Unity, parser, or renderer dependencies. Wrappers pass pre-normalized model and animation IR into this crate and read contiguous output buffers back.

RuntimeAppendTransformDescriptorV1

An append transform (rotation and/or translation, optionally in local space). A target may have at most one append transform.

RuntimeBoneDescriptorV1

Absolute PMX/MMD-space rest position and per-bone metadata.

RuntimeBoneMorphOffsetDescriptorV1

RuntimeGroupMorphOffsetDescriptorV1

RuntimeIkLinkDescriptorV1

One link in an IK chain.

RuntimeIkSolverDescriptorV1

An IK solver attached to one IK bone.

RuntimeInstance

RuntimeModelDescriptorError

Detailed validation failure. path always identifies the offending descriptor field, including its zero-based array index where applicable.

RuntimeModelDescriptorV1

A host-independent snapshot of all runtime model data needed by v1.

RuntimeMorphDescriptorV1

Bone and group morph offsets. Offsets are grouped by morph_index by the compiler and exposed in ModelArena through spans.

RUNTIME_MODEL_DESCRIPTOR_VERSION_V1

build_bones_from_flat

build_ik_solvers_from_flat

build_ik_solvers_from_flat_iter

build_morph_init_from_flat

build_morph_init_from_flat_iter

build_morph_init_from_offsets

Build the canonical grouped morph tables used by every runtime input adapter. Inputs retain their source order within each morph bucket while this function owns span construction, index checking, and cycle traversal.

compile_runtime_model_descriptor_v1

Compile a validated v1 descriptor into the immutable runtime arena.
