I'm trying to render a starfield properly. I'm doing something similar to the new google maps zoomed out where you can see the entire planet and stars. However, right now in my implementation i'm basically drawing a sphere with the stars in the scene. When you zoom in or out the stars get zoomed in or out, but i think the right implementation is that they don't move. How would I properly render that?
basically right now the sky is a sphere(5000), and the earth is a sphere(10) and the camera moves in and out looking at the earth. when i zoom in, a narrower area of the sky is shown, I don't think this is correct, is it? Would I scale the sky inversely to the camera zoom? -> the more the camera is zoomed, the smaller the sky is?
