12. Ne oldu imdi?Her bir nokta i巽in y端kseklik bilgisi var.SetUpIndice her noktan脹n array脹 i巽in vertex.SetUpIndices Terraini kurmak i巽in her 端巽gene 3 indis.Draw indisler dizileri izin verdik巽e 端巽genleri renderlemeye devam et.
18. I脹k?T端m vertexlerin normalizesini istiyorum.Bu verileri vertex datas脹na iletmeliyimBir normalize, bir renk ve bir pozisyon XNA i巽in fazla!Fakat bu sorun olmasa gerek?
26. Ne ekledik?Biraz ho g旦r端ns端n istedik, g端ne ekledik, hava ekledik, su ve sis eklemeye 巽al脹t脹k.Heightmap d端zenleme ara巽lar脹 ekledik, colormap eklemeye 巽al脹t脹k pek de baar脹l脹 olamad脹k.Kamera kontrol kodlar脹 巽arpt脹k sadan soldan hemen ekledik
