Haskell - düşük kalite kodu
Bunu yazarken çok yorgundum.
Her neyse, projeksiyon fikri ile fazla ileri gitmiş olabilirim, işte programın kullandığı projeksiyon. Temel olarak dünyayı bir küp üzerine yansıtmak ve sonra açmak. Ayrıca, bu projeksiyonda, gölge düz çizgilerden oluşur.
Program, geçerli tarih / saati kullanır ve stdout'taki bir PPM dosyasını çıkarır.
