Rendering pretty sky in Around The World game

The article discusses the rendering of the sky in the Around The World game, a 3D game developed by a solo developer. The sky is rendered using a technique called 'skybox' which is a pre-rendered image that is repeated to create the illusion of a vast sky. The author notes that they use a 4k texture for the skybox, which is a 4096x4096 pixel image. They also mention that they use a technique called 'atmospheric scattering' to add a realistic effect to the sky. The author shares a screenshot of the game showing a beautiful and realistic sky with a sunset, and notes that they are still working on improving the game's graphics.
