All you need is a couple of stacks of sponges, a nether portal, a couple of shulker boxes full of sand, a shovel with mending on it, an experience farm for repairing the shovel repeatedly, and it goes a lot faster if you also have some torches. Don't forget to break all the kelp at the bottom, before you start.>> <<@JobvanderZwan says : The Dutch, doing their best Bane impression: "For you.">> <<@dudo2249 says : "dimming the sun takes an unexpected effort " ahhhh>> <<@lorimartabin7992 says : It's easy though? Takes like 5 minutes. Just dig straight down and drain it into Hell. It'll all evaporate and any lava on the way will freeze solid.>> <<@theindiefanclub says : I loved your animation, something which would be cool is a version where as a given point fills with more water, it becomes gradually more blue, with the flashes "leaving behind" their color>> <<@uchinanchuu58 says : Try draining an ocean in Minecraft. Nearly impossible.>> <<@yert527 says : This video is actually about AI.>> <<@satibel says : I thought about the flood fill but kinda without reversing it, that should be more or less equivalent, for each point, you flood fill set it to the sea level if it's lower than the sea level (which ignores points that have already been set) Then you repeat for each point that was in the area with the drain. if you use a different color for each point and height (e.g. uvw map) that gives you a map of every basin with its height.>> <<@adilOuakrim says : Draining>> <<@muggyate says : just re-run the same algorithm for each inland sea again to find inland seas of those inland seas untill the algorithm finds no inland seas witin an inland sea>> <<@codeviper8665 says : The whole time I was thinking "this would be useful for animating "drain the oceans" by xkcd and and the end it turned out it was!>> <<@Neeravround2 says : Where would all the water go?>> <<@TheRyujinLP says : Cool, don't care. In fact I'm probably gonna double down now. Not everything needs to literal and if you don't like, don't care lol.>> <<@smsfrancis says : Everyone knows water and lava come from a source block. Just find it 😊>> <<@ladyalicent705 says : “Bro it’s easy, just dig down” - My terraria character>> <<@Skibidi_Dih says : Just revert gravity for a moment it’s so easy ✌️ 😭>> <<@ItsMeNebulae says : Please make a part 2 with the oceans teleported to mars>> <<@ChhayaWankhede-t3t6e says : What is shape of earth If it geoid ,like If it flat no , like>> <<@squirrelg5135 says : Just remember to send all that water to Mars>> <<@andy02q says : Just turn the earth upside down.>> <<@rrigamondi says : It's also difficult because where are you putting that water>> <<@mduvigneaud says : I was yelling at my screen saying "Flood fill! Flood fill! Flood fill!" Oh, you already knew! I've written a broken version of flood fill that never traversed in the -x direction. I've also written a different broken version that sometimes had weird shadows along |x|=|y|. I've also written water flow sims that *did* work correctly. lol!>> <<@akifunmc says : Clicked to watch an ocean be drained. Stayed to learn how to create an ocean filling algorithm.>> <<@MindsLabteam says : I think the video could have benefited from more real-world examples.>> <<@xKiNx says : Drain the ads>> <<@julianepelt5658 says : Netherlands be like>> <<@Memer9456 says : yeah too much water>> <<@Apfelvater says : THE OCEAN IS A LIE!!>> <<@otakarbeinhauer says : Ok, how is this not extremely obvious that draining oceans is fucking obvious?>> <<@LanDuong-u8m says : This was 10/10 clarity.>> <<@bigsmiler5101 says : I actually watched this for 54 seconds. The comments are far more interesting AND EDUCATIONAL.>> <<@uzi1476 says : the Combine taking notes rn>> <<@mowuvz3672 says : In a billion year it won’t be a problem as sun will be so hot that oceans will evaporate>> <<@Technodrone108 says : Why dont we simply drink the water? Are we stupid?>> <<@jezuconz7299 says : 4:19 hey I live in one of these giant pixels!! Southmost Spain almost touching Africa>> <<@katetoolate234 says : 5:30 Randall Monroe? 😆 He drained them all to Mars!>> <<@jonahw6516 says : Sooooo what's the point of the video, If you literally invalidate your own algorithm as a bad algorithm at the end? Yeah it's an interesting algorithm but it doesn't work. The best algorithm would like be to run computer aided simulations of all the points which do not have an exit. Basically if a point has a lower point next to it or a lower point that is connected to it by points of equal level, then that point has an exit. You can do this with a depth first search basically. Starting with all the points which have a lower point next to it and the working up in elevation checking for connecting flat zones. The remaining areas will be zones where water drains to but not away from and those points are where you put your drains. Still obviously assuming you are draining to somewhere and no topology changes while doing so.>> <<@silentblackhole says : Please pick some different music for your videos. I don't like the bass. It's distracting, slow and plodding along. It's the music you would expect if Eeyore (from Winnie the pooh) was making a YouTube video. I love the topics, the content and the video itself though.>> <<@anothertubephile says : The question is why would anyone on earth drain an ocean?>> <<@julianparsons3027 says : 0:02 ...Well, I would hope so.>> <<@eliteal2188 says : Except you could get rid of all the silly algorithms and not worry about basins in basins by just using 3D calculus space to find local critical points corresponding to local low points in the topology. If you had good enough data that would literally solve the whole problem of where to put the drains in one easy step>> <<@recordkeepingandinformatio8206 says : when you try to build a guardian farm:>> <<@omarhussain5066 says : Honestly I was focused on how much your audio is sped up, i think its 1.2 right? Not complaining just noticing. Love the videos btw>> <<@84com83 says : Please tell me why ?>> <<@gurumoorthi-g1k says : Watching this at 2 AM hits different.>> <<@bignerd3783 says : terraria moment>> <<@ik-y says : 1:23 a nice zoom on Comoros, never seen that before !>> <<@5Davideo says : Also, that's a hell of a lot of water and there's nowhere to put it.>> <<@nicokuhne3255 says : when i told my politics class that i look at the headlines of BILD to know what the "bad" people are talking about, they looked at me like i was some sort of stupid alien.>>
