minus-squarejlow (he/him)@beehaw.orglinkfedilinkEnglisharrow-up19·1 year agoAre there non-circular cylinders or what does that even mean.
minus-squarepearsaltchocolatebar@discuss.onlinelinkfedilinkEnglisharrow-up7·1 year agoMaybe they meant prism, since a cylinder is technically one.
minus-squareBlóðbók@slrpnk.netlinkfedilinkEnglisharrow-up3·1 year agoMaybe what they’re trying to describe is a torus
minus-squareletsgo@lemm.eelinkfedilinkEnglisharrow-up5·1 year agoNo they’d only model a bull as a torus.
minus-squareAggressivelyPassive@feddit.delinkfedilinkEnglisharrow-up2·1 year agoNow, how exactly is a penguin toroidal?
minus-squareletsgo@lemm.eelinkfedilinkEnglisharrow-up3·1 year agoIt has a single hole through its body from its mouth to its arsehole. IANAB but I think all other holes have at least a membrane between one end and the other. So it’s topologically equivalent to a teacup and a torus.
minus-squarejlow (he/him)@beehaw.orglinkfedilinkEnglisharrow-up1·1 year agoImagine a donut-shaped penguin, love it! 😸
minus-squareAggressivelyPassive@feddit.delinkfedilinkEnglisharrow-up2·1 year agoMaybe having halfspheres at the top and bottom? So more like a gas tank, less like a piece of sausage.
minus-squaresqw@lemmy.sdf.orglinkfedilinkEnglisharrow-up1·1 year agoonly thing i can figure is maybe technically you could call an ellipsoidal prism a cylinder also? seems like a stretch.
minus-squarejlow (he/him)@beehaw.orglinkfedilinkEnglisharrow-up1·1 year agoYeah, I also thought that there might be a cylinder based on a ellipse. Not very common but possible
