## Architectures Notes
- Use Top Level Acceleration Structure (TLAS) for instancing and describing geometry
- Use Bottom Level Acceleration Structure (BLAS) for actually storying geometry inside of AABB regions
- Keep BLAS AABBs condensed (less negative space), but don't overlap them either
- We could have an AABB system that automatically generates it from placed level geometry? Too overkill?
