Real time rendering of the Earth in Gaia Sky with surface, cloud and height virtual textures.
Implementing proper virtual texture support in Gaia Sky has been on my to-do list for many years. And for many years I have feared that very item, as the virtual texture mechanism is notoriously complex and hard to implement. However, once working, they are very cool and bring a lot of value to software like Gaia Sky. In this post, I describe and discuss my implementation of virtual textures in Gaia Sky in detail, and provide a thorough examination of some of its most interesting points.
