Different setting, same rodent problem. (Okay, it's a Cole Habitat, not an O'Neill Cylinder, but the point still stands.)

Yeah, that's what motivated me to do these models/renders in the first place. Here's a render from the surface of a ringworld showing what I was talking about with fish-eye lens distortion

what you would perceive when standing on the ringworld would be the ring going straight up, but in ray tracing you get a tilted looking projection unless the ring is right in the center of your field of view.

Having watched plenty of rugby and gridiron , I've noticed that when the wind is significant to one side of the pitch, it can drastically influence play strategies; also, switching ends doesn't even things out as much as might be implied; second half tends to be a bit slower for most of the teams I've seen play. A disadvantageous wind along the length of the pitch tends to help the team initially attacking from up wind a bit more than the second, as the first team with the advantage tends to make better use of it.

And a 15% easier in antispin vs 15% harder spin throw definitely means sufficient difference to alter play... and a lot more missed throws due to differences in ball performance.

I don't think that "15% easier" is an accurate characterisation. If you throw the ball the same it will go ~6% further. But since a good pass in Rugby is much shorter than the distance one can easily throw a Rugby ball that doesn't really help much. A cross-wind makes passes faster or slower, which does matter. The Coriolis effect only makes them come in a little low or high: that requires practice to adjust for, but equally to east or west.

That may be the most depressing thing I've seen in months.

Yeah, we don't do much with it in-setting. It's just there as background material and a Dire Warning To Future Generations to not let any other company pull the same sort of stunt.

I built a little calculator for the thickness of the structural hull, mass of the hull and contained atmosphere for a rotating cylindrical habitat, as functions of the length and radius, the "gravity" and air pressure, the mass-per-unit-area of the shielding, armour, landscaping, and fittings, and the strength and density of the structural material. It's an Excel workbook with no macros.

Just at the moment the list of possible building materials is a bit incomplete and some of the values for strength questionable.

I put it on Dropbox for review and personal use: https://www.dropbox.com/s/7iilf35hdx...ator.xlsx?dl=0
