Then I found this video: https://www.youtube.com/watch?v=9cTE7pdlnHg

IRSTUFF: I'm familiar with the piecewise differential approach but only in the conceptual sense of explaining view factor. I've never had to actually use it to integrate some arbitrary geometry. Usually the formulae are provided because of how math intensive it is to compute various common...
So I have consulted multiple sources both in books and online regarding the various view factor geometries and their formulae but I've yet to find one where the outer shell of a hemisphere (convex surface facing up) is situated in the center of a square cavity and exposed to the inside surfaces...
