I saw the following representation in a paper that I was reading. Can anyone can shed any light on how it was developed?

Don't do it! (unless it's for an art project)
Circular views are harder to interpret (e.g., harder to compare values and slopes). Straight lines turn into curves and curves turn into straight lines. Adding 3-D can only make it worse with additional obscuring and perspective distortion.
The paper Graphical Tests for Power Comparison of Competing Designs by Heike Hofmann et al. provides some experimental support for the above statement. One of their test cases shows that circular charts underperform even when the data is naturally circular (wind direction in their case, time of day in the question's example).
Something in between the two images below from the same paper should be easier to read and compare values across time. That is, I'd like to see the information from the first (7+ summary values per time interval) encoded more like the second (with lines and shaded areas).
