The OSM pipeline pointed at actual mountains. Both levels ride the real
terrarium DEM (Coot-tha's range tops at 287 m, Gravatt's at 196 --
matching the survey numbers) with the real roads draped and carved over
it: Sir Samuel Griffith Drive winding up one side of town, Mount
Gravatt Outlook Drive zigzagging up the other. Race mode is 3 laps of
the mountain; the drag finder even discovered a 1080 m strip through
Mount Gravatt's suburbs (Logan Road, of course it is).
Pipeline upgrades earned along the way, all reusable:
- trace: RacePath mode now STITCHES every OSM way sharing the name into
one chain by shared endpoints (SSG Drive is 19 segments; tracing only
the longest produced a fraction of the route) and samples densely --
16 points cut hairpins cross-country and gridded race starts in a
paddock.
- 9th builder arg selects the raw-terrain texture. Bushland levels pass
"grass" (tiled at 3 m -- 18 m tiling reads as macro-photography lawn
blades under the car) which also enables forest fill: ~2600 extra
gums, 65% biased to within ~150 m of roads, where the driver's eyes
actually are.
- amenity=parking polygons are now PAVED (draped asphalt) as well as
stocked with parked shitboxes -- a summit lookout carpark is a
burnout pad, not a dirt patch. Both summits come ready.
- man_made mast/tower ways become tapered lattice towers with a cage
and whip antenna, built from beams into the steel bucket. Mount
Gravatt's telecom tower stands over its carpark.
- Levels can carry their own sky: levels/<id>/sky_<time>.jpg overrides
the global panorama for any time of day, including day (previously
always procedural). Both mountains ship FLUX skies with the Brisbane
skyline on the horizon; Gravatt also has a sunset one, because John's
reference photo demanded it.
Suite green at 11 levels. Next burnout spot: the Gateway Bridge, when
the details arrive.
