android - Libgdx - 使用 MipMaps

Question

TextureLoader.TextureParameter param = new TextureLoader.TextureParameter();
    param.minFilter = Texture.TextureFilter.MipMapLinearNearest;
    param.magFilter = Texture.TextureFilter.Nearest;
    param.genMipMaps = true;

    manager.load("MainMenu.pack", TextureAtlas.class);

    manager.load("GameScreen/player.png", Texture.class, param);
    manager.load("GameScreen/obstacle.png", Texture.class, param);
    manager.load("GameScreen/star.png", Texture.class, param);

MainMenu 还在 .pack 文件中设置了过滤器。

现在这一切都是自动完成的吗？或者我是否必须手动告诉应用程序使用 mipmap，我可能必须这样做，但我该怎么做？

由于official LibGDX wiki :

When opting to use mipmaps, the Texture will create them at instantiation time. MipMaps are pre-calculated, optimized resized copies of the same image to save on computation time when resizing the texture to fit a rectangle. Smaller (halved) copies of the same image are created and uploaded to the GPU and used for different sized geometries instead of being shrunk on the fly. It adds to memory consumption but makes rendering faster.

是的 - 它们是自动生成的。
