Mow the Ring

The Nürburgring has been left to the weeds. All 20.7 km of it. You have a very fast mower.

A fusion of two ZeroMind worlds:

• Nürburgring Drive — the full Nordschleife: 240 Hz pure-Luau vehicle physics, lap + sector timing, minimap, cockpit view (C).
• Mow Rush — the shader-grass mowing game: per-cell cut state streamed to the GPU, blades that bend away from the deck, mow stripes baked from your heading.

How it plays

• Drive with W/A/S/D or arrows. R resets to the track, C toggles cockpit, M/T/B gearbox/TC/ABS.
• The entire road ribbon is overgrown, end to end. Your machine carries a mowing deck: anything you roll over gets cut, at any speed.
• Fresh grass scores. Keep finding uncut line and the combo climbs to x5; grinding over your own stubble drains it. The deck is ~3.4 m wide and the road is ~9 m — one lap physically clears at most ~38 %, so your line matters, and repeat laps mow different lanes.
• Cross the start/finish line and the lap is graded S/A/B/C from coverage × best combo, right next to your lap time. Coverage milestones (25/50/75/90 %) flash as the Ring gets cleaner across laps.
• The GROUNDSKEEPER panel (top right) tracks grass score, combo, total Ring coverage, and your best lap rank.

Under the hood

Cut state lives in track coordinates — s meters along the lap, d meters from the centerline — split across 259 contiguous road segments, each a small s×d cell texture. Every grass blade is generated along the actual road ribbon (camber and bumps included) and carries its cell UV in vertex attributes, so the shader truncates cut blades to stubble straight from the segment texture with no world-space mapping. Cutting is a disc in (s,d) space at the deck's track position, so it is exact at 200 km/h. The scene runs the v7 player system (PlayerPrototype + spawns).
