skinnedPoseUnionAabb property

Aabb3? get skinnedPoseUnionAabb

For skinned primitives only: union of vertex positions across every pose the primitive can take under the file's animations, computed offline by sampling each animation's keyframes and applying the resulting joint palette.

In the same local space as bounds_aabb (the mesh's vertex-position space). Lets the runtime cull skinned content soundly instead of treating it as always-visible. Absent on unskinned primitives, and on skinned primitives when offline pose-union analysis isn't available (e.g. older importer output).

Implementation

Aabb3? get skinnedPoseUnionAabb =>
    Aabb3.reader.vTableGetNullable(_bc, _bcOffset, 16);
