CPU trilinear lattice deformation for procedural 3D scale/squash-stretch animation: per-control-point scale + offset, model/array binding, deformed position/normal cache, script API (anim.newLattice + AnimLattice class) and gfx.newMeshFromArrays / gfx.updateMeshVertices script wrappers so scripts can upload deformed meshes per frame. Includes unit tests and the examples/lattice-deform demo.
