I have a quick question on the surface area number reported by the Models module. I did a quick exercise where I made a 5cm sphere (well, as close as I could get by hand using the ruler) and compared reported values to hand-computed values - 4pir^2, etc.
The value I get for surface area is what I would expect, but I was a little confused from earlier posts (Using surface cut of segment editor to measure area) regarding counting front-facing and back-facing polygons in the area calculation, and needing to divide by 2.
For a “closed surface representation”, such as a segment converted to a model, it seems that the computed surface area is the outward-facing polygons only, and one does not need to divide the reported quantity by 2. Is this correct?
