What commenters say

• The article's visuals and explanations are impressive and easy to understand, making complex concepts accessible to a wide audience.
• The use of physics-based models is preferred over graphics hacks for achieving realistic rendering results.
• The article's approach to rendering skies and atmospheres can be applied to various fields, including game development and planetarium simulations.
• Some commenters pointed out the importance of considering twilight effects in sunset models, as the sky does not immediately go black after the sun dips below the horizon.
• The article's content is relevant to various projects and interests, including procedural planet generation and sky rendering plugins.
• The implementation of atmospheric scattering and other effects can be challenging, but the results are worth the effort, producing stunning and realistic visuals.
