Function: buildBaseOccupancyGrid()
buildBaseOccupancyGrid(
units,openings,opts?):BaseOccupancyGrid
Defined in: packages/wayfinding/src/occupancy-grid.ts:361
Rasterizes the level-static portion of the grid — walls, opening gaps, and fixture/kiosk obstacles (steps 1-3 and 5 of buildOccupancyGrid's doc comment) — deliberately excluding the two rung-specific dynamic layers (wall-vertex clearance discs and the blocked-unit fill, steps 4 and 6). Those are applied per relaxation rung by restampOccupancyGrid instead, so that the (comparatively expensive) wall/opening/fixture rasterization runs once per level per IMDF version rather than once per ladder rung and once per route call (issue #483; see getBaseOccupancyGridForLevel in grid-relaxation.ts for the cache built on top of this).
Returns a BaseOccupancyGrid: an OccupancyGrid plus the cell-space ring and door-gap geometry restampOccupancyGrid needs, so it never has to re-derive that geometry from lng/lat.
Parameters
