In creating this space scene, I used three spheres (not including the stars), a disk, and a paraboloid to create the entire scene. I used simple shaders for the planets and spaceship, and I used one ambient light and one directional light. This particular scene was a learning experience for me, and I was constantly getting confused on where I was in 3D space.
I finally got a grasp on what I was doing and I was able to create the scene more quickly. I used spheres, cylinders, disks, hyperboloids, paraboloids and cones to create this scene. I tried (and failed?) to mimic a candle light, but I couldn't figure out how to make the shader more transparent.
