The algorithm doesn't seem to be complete, it can't handle concave shapes with trapped water or trapped air. But that's probably too much to ask.
Edit: to illustrate the point, this iceberg had trapped air before it stabilized and removed all air, which is physically impossible: https://imgur.com/a/uiaW1qN https://imgur.com/a/uiaW1qN
- ledauphin 6y agoon the one hand, this is clearly a 2D simplification of a 3D problem. on the other... if you imagine your spiral as projecting outward a non-infinite distance, how could it possibly "trap" air? the air would flow toward (and away from) the viewing plane very quickly.
- mojuba 6y agoYes but surely concavities with trapped air are possible in real life? Not necessarily in the form of a spiral.
