Procedural celestial rendering for 3D navigation

Finding the best suitable environment for 3D navigation that utilizes at least six degrees-of-freedom is still difficult. Furthermore, creating a system to procedurally generate a large virtual environment provides an opportunity for researchers to understand this problem further. Therefore, we present a novel technique to render a parametric celestial skybox with the ability to light environments similar to natural color corrected images from telescopes. We first pre-compute a spherical ray map that corresponds to the cubemap coordinates, then generate stars and dust through a combination of different noise generation shaders.
