LAB 153 / GPU BROADPHASE

Spatial neighbors

Packed cell keys turn a particle swarm into a sortable broadphase: update, sort, then connect adjacent entries from the same spatial cell.

Stress the broadphase

GPU sort uses the official BitonicSort addon. The grid cell is fixed at 16 × 8 × 16; the visualization shows candidate links, not a claim of exact nearest-neighbor topology.

The route will identify whether the current renderer is using GPU bitonic sorting or a CPU uniform-grid proxy.
