BabylonJS - Vektör Pozisyonu ve Döndürme

Tarayıcınızda aşağıda verilen demo bağlantılarını çalıştırın. Aşağıda verilen demolarda x, y ve z eksenini çizdik. Pozitif ve negatif yönde x, y ve z ekseninde çizilen sayılar vardır. Aynısını tarayıcıda çalıştırın, ihtiyacınız olması durumunda değerleri değiştirin ve şekillerinizi, ağlarınızı çizin, konumlandırın ve x, y ve z eksenlerinde nasıl işlediklerini görün. X, y ve z eksenlerinde belirtilen sayılarla, ağın konumlandırmasının nasıl yapıldığını görmek yardımcı olacaktır.
