# @neith/engine-geometry-cache

Neith sovereign Alembic/VDB geometry-cache playback: per-frame vertex-position +
topology mesh caches (constant + changing topology, point caches, mesh
sequences), per-vertex motion-vector/velocity computation, base+delta-frame
compression with quantisation, a streaming resident-frame window, a LOD chain, a
sequencer track with retime/speed scrubbing and per-sub-mesh material
assignment, a VDB volume-density cache, and a USD time-sampled-points equivalent
cross-referencing the sim (157) and export (138) phases (phase 173.9)
