Próbuję narysować jeden blok 3D!Zmiana kąta perspektywy z prawej na lewą, w CATransformLayer iOS przy użyciu CATransform3D
Za pomocą 2 warstw i wygląda dobrze w 3d dla prawej stronie. zobacz załączony obraz.
Kiedy próbuję ponownie użyć tego samego kodu do drobnych modyfikacji dla lewej stronie! wygląda dziwnie. Patrz załączony ryk obrazu
czuję możemy poprawić, jeśli możemy zmienić kąt widzenia, ale nie wiem, jak to osiągnąć.
przy użyciu transform.m34 dla perspektywy. jakakolwiek pomoc byłaby bardzo doceniana.
Oto kod źródłowy, którego używam.
