Time of Day

Time of Day

I created Time of Day because I was not satisfied with the available solutions to render dynamic sky domes in Unity. What bothered me most about the existing solutions were the often chaotic code bases and the lack of physical accuracy. With Time of Day you can expect a thoroughly documented, well-written and highly optimized code base with references to the scientific papers it is based on.
