Having previously used domes as a means to display distant sky, I am now investigating the use of blended skyboxes. Skyboxes allow the use of up to six textures to create a seamless sky. However, there usual limitations are that they don’t animate. They are low render cost, high quality images that display a still sky.
I am investigating methods to use skyboxes with animation, either as blending of pre-rendered textures or ideally, as realtime rendering based on satellite images.
