本文介绍了一种在游戏开发中创建3D背景天空的方法。通过使用3D建模软件（如Maya或Blender）制作天空球体并映射纹理，然后将其导出并在游戏中加载该模型及其纹理。这种方法确保了当场景中的其他对象被渲染时，天空球体不会写入深度缓冲区，从而只在没有其他对象遮挡的地方显示天空。

You can make a small skysphere or box, as suggested by Davido and turbovonce's link, which is centered around the viwer and fits into the frustum. You draw this first, without writing into the depth buffer. Then you draw the other stuff and as the skybox has not written to depth buffer it is just overwritten, except the parts where no scene objects are rendered, which are exactly the parts of the image where the sky should be visible.

Create a sphere in a 3d modeling app such as Maya or Blender and map a sky texture to the sphere. Export the model then load the model and its texture into the app, place in the scene. You should now have a background sky rendering in your game.
