const CLUSTER_COLUMNS: [f32; 5];Expand description
The columns the debug floor’s lights stand in.
A regular lattice, so a cell’s count is predictable from where it is: a light reaches a disc of the floor whose radius follows from its height and its range, the discs of one row merge into a band, and the rows are far enough apart in depth that a cell holds the lights of one row and not its neighbour’s.
