AnimatedMesh (Mibo)

AnimatedMesh Type

Namespace: Mibo.Animation
Assembly: Mibo.MonoGame.dll
Base Type: ValueType
All Interfaces: IEquatable<AnimatedMesh> , IStructuralEquatable
Kind: Struct

A mesh with skeleton data for GPU skinning.

Load once from an Assimp Scene via AnimatedMesh.fromScene, then share across all entities that use the same mesh. Each entity computes its own bone matrices via AnimatedMesh.computeBoneMatrices and passes them to Draw3D.drawSkinnedMesh.

Record fields

Record Field	Description
`BindLocalPoses` Full Usage: `BindLocalPoses` Field type: `Matrix[]`	Per-bone bind LOCAL pose (node-local transform from the Assimp node tree, in MonoGame row-vector convention — transposed like `InverseBindPose`). Used by `computeBonePalette` as the fallback for bones that a clip does NOT animate. Falling back to `Matrix.Identity` here (the old behavior) collapsed every channelless bone to the skeleton origin: in clips like 'idle'/'jump' that animate only a subset of bones, the unanimated root/legs snapped to origin and dragged their descendants there, making limbs vanish. The bind local pose holds the bone at its authored rest position instead, so unanimated limbs stay put. Field type: `Matrix[]`
`BoneCount` Full Usage: `BoneCount` Field type: `int`	Field type: `int`
`BoneLookup` Full Usage: `BoneLookup` Field type: `IReadOnlyDictionary<string, int>`	Bone name → bone index lookup for `BoneRef.ByName` queries. Built once at load from `BoneNames`; retained on the record so bone queries and attachment draws can resolve names without re-walking the array. Field type: `IReadOnlyDictionary<string, int>`
`BoneNames` Full Usage: `BoneNames` Field type: `string[]`	Field type: `string[]`
`BoneOrder` Full Usage: `BoneOrder` Field type: `int[]`	Bone indices sorted by ascending hierarchy depth (parents before children). Depends only on `BoneParents`, so it is precomputed once at load and reused every frame by `computeBonePalette` — avoids the per-frame depth recursion and sort that the hot path would otherwise pay. Field type: `int[]`
`BoneParents` Full Usage: `BoneParents` Field type: `int[]`	Index of each bone's parent in `BoneNames`, or -1 for a root bone. Built from the Assimp node tree so `computeBonePalette` can compose parent chains (local pose × parent world pose). Without this, child bones move in isolation — the classic "exploding joints" symptom. Field type: `int[]`
`InverseBindPose` Full Usage: `InverseBindPose` Field type: `Matrix[]`	Field type: `Matrix[]`
