الجزء 24: المناطق والتآكل

• أضف حدًا من المياه حول الخريطة.
• نقسم الخريطة إلى عدة مناطق.
• نستخدم التآكل لقطع المنحدرات.
• ننتقل الأرض لتخفيف الإغاثة.

كيف يتم اشتقاق صيغة عدد الخلايا في المنطقة السداسية؟

مع نصف قطر 0 ، نتعامل مع خلية واحدة. جاء من 1. مع نصف قطرها 1 حول المركز ، هناك ست خلايا إضافية ، وهذا هو $$ . يمكن اعتبار هذه الخلايا الستة نهايات ستة مثلثات تلامس المركز. مع نصف قطر 2 ، يضاف صف ثان إلى هذه المثلثات ، أي يتم الحصول على خليتين إضافيتين على المثلث ، وإجماليًا $$ . مع نصف قطر 3 ، يتم إضافة صف ثالث ، أي ثلاث خلايا أخرى لكل مثلث ، وإجماليًا $$ . وهكذا دواليك. أي ، بشكل عام ، تبدو الصيغة $$$6 (sum_ (i = 1) ^ r i) +1 = 6 ((r (r + 1)) / 2) +1 = 3r (r + 1) + 1 = 3r ^ 2 + 3r + 1$.
