Task 6: leonida/emit.py (chunk_box, split_by_chunk, chunk_payload und die
Chunk-lokalen three.js-Koordinaten, write_chunks, write_debug_png) sowie
run.py als Ablaufsteuerung, die alles aus den Tasks 3-5 zu 144 Chunk-Dateien
und einem Manifest unter public/data/vice-a/ zusammenfuehrt.
Zwei Abweichungen vom Referenzcode der Aufgabe, beide durch Gegenrechnen
gegen die dort genannten Realwerte gefunden:
- test_emit.py::test_coordinates_are_chunk_local_three_js gab im Original
das ungeschnittene BIG (spannt vier Chunks) direkt an chunk_payload();
chunk_payload() clippt selbst nicht (das tut in run.py split_by_chunk_all
vorher), darum lag der Rand bei x=300 statt <=250 und der Test schlug mit
dem gegebenen Code fehl. Fix: BIG vor dem Aufruf mit split_by_chunk auf
Chunk (0,0) zuschneiden, wie es run.py fuer "land" ohnehin tut.
- run.pys Filter "Gebaeude, die zu >50% in einem Strassenpolygon liegen,
gelten als Strasse" pruefte im Original ALLE rohen Gebaeude gegen
road_polygons(labels) direkt. road_polygons() zaehlt "spekulativ" selbst
zu den Strassenklassen (ROAD_CLASSES) und schliesst zusaetzlich mit
disk(3) gegen Strassennamen; ein isoliertes "spekulativ"-Gebaeude
ueberlappt sich darueber praktisch mit sich selbst. Ergebnis am realen
Mosaik: von 267 rohen spekulativen Gebaeuden ueberlebten nur 3 (statt der
in der Aufgabe genannten Groessenordnung von 258), und die Schliessung
riss zusaetzlich 211 gewoehnliche graue Gebaeude mit heraus, die die
Notiz aus Task 5 ausdruecklich nicht meinte ("die ROTEN Flaechen ...
werden abgezogen"). Fix: eigenes, unzweideutiges Strassenmass nur aus
"strasse"/"weg" (ohne "spekulativ", ohne Namens-Schliessung), Pruefung
nur auf spekulative Kandidaten begrenzt. Ergebnis: 2.348 Gebaeude, davon
263 spekulativ (Aufgabe: 2.352 bzw. 258) - Wahrzeichenhoehen (68 Stueck,
31-248 m) und Palmenzahl (2.133) treffen die genannten Referenzwerte exakt.
Pipeline-Lauf am gecachten Mosaik: 144 Chunk-Dateien + Manifest, 2,5 MB
gesamt (Budget 10 MB), groesste Datei chunk_9_1.json/chunk_10_1.json mit
je 40 KB. Alle drei Toleranzgrenzen (wasser/strasse/gebaeude) eingehalten.
Debug-PNGs stichprobenartig gesichtet: Kuestenlinie, Strassennetz
(inklusive Kreuzungen und einer Auffahrt-Rampe) und ein Strand mit
Palmenreihe liegen deckungsgleich auf dem Mosaik; der wasserreine Chunk
(4,10) zeigt korrekt keine Vektoren.
