My laptop was crashing repeatedly and I needed to back up the data. I had done an rsync from a couple of important directories on the laptop hard drive to an external drive:

rsync \
	--archive \
	--compress \
	--progress \
	--append-verify \
	--partial \
	--inplace \

Design Goals

• Avoid lookups in hot paths I.e. per-entity
  • 'Random' lookups cause cache misses whereas linear scans are much more cache coherent and so often perform much better

How things work on main at a5a457c3c82cc2e501bf6e85a2e2d07b5b7838a9

• extract_meshes:
  • iterates an ECS query (good)
• filters out non-visible entities based on the ViewVisibility component (good)
