Detailed Description

Manages GPU data for a sparse subset of active leaf cells.

This repository holds data for "enclave" cells designated for GPU offloading. It is designed to be rebuilt whenever the mesh changes. Data is stored in a Structure-of-Arrays (SoA) layout for coalesced memory access on the GPU.

The lifecycle is as follows:

  1. startCollection() - Clears old data and prepares for a new build.
  2. bookmarkCell() - Called repeatedly during a traversal to collect leaf cells.
  3. buildFromBookmarks() - Allocates GPU memory and copies data from host.
  4. [COMPUTE ON GPU]
  5. syncDeviceToHost() - Copies results from GPU back to the host repository.
  6. clear() - Frees all GPU resources.
