# 로우크롭 트랙터 (1939~1953 파몰 H형) — Blender Python 코드만으로 만든 모델. # 큰 뒷바퀴와 앞쪽에 모인 쌍바퀴(세발자전거형), 좁고 긴 보닛, 보닛 위로 솟은 배기관·흡기관, # 보닛 위를 지나 앞 받침대까지 이어지는 긴 조향축이 이 형식을 알아보게 하는 특징이다. # 뒷타이어는 회전체(lathe) 단면에 갈매기(쉐브론) 러그 46개를 bmesh 로 붙여 만들고, # 보닛·라디에이터 덮개는 둥근 단면 돌출, 펜더는 원호 띠에 두께를 주어 만들었다. # 같은 바퀴·러그·볼트는 메시를 공유하는 복제로 배치했다. 단위 m, 앞쪽이 -Y. from atelier import * SHOT = {"azimuth": -40, "elevation": 13, "lens": 55, "light": "studio", "background": "#26303a"} #
