01:23 Taoki https://www.youtube.com/watch?v=ztAg643gJBA I just saw this and was like "wow". Thought it would be worth sharing... also I would love to see the engine fork where this was implemented.

02:22 NathanS21 Taoki the links to the spherical world stuff are all in that youtube videos description.
02:42 Ruslan1 Hi NathanS21 in YouTube’s
03:03 NathanS21 yes
03:10 Ruslan1 NathanS21: how are you
03:11 NathanS21 Doing alright.
03:12 NathanS21 I've been pretty busy lately, and haven't been very active on the forums or in IRC.
03:12 Ruslan1 Have you play blocky survival it is new server
03:12 NathanS21 I have not.
03:13 Ruslan1 Ok
03:13 NathanS21 I really only play on one server, and that's just for the youtube series, but I might check that server out.
03:13 Ruslan1 Ok
03:14 Ruslan1 What server
03:14 NathanS21 Illuna
03:14 Ruslan1 Ok
03:14 Ruslan1 It is vip
03:15 NathanS21 I believe so.
03:15 Ruslan1 😃

09:30 Taoki NathanS21: Ahhh... sorry about that, missed them. Good to know, should try that out sometime :)
09:30 Taoki But yeah, really ingenious thing they did with the engine.
09:31 Taoki Wanted something like this in Minetest or a similar project for ages, but didn't imagine any way that I could actually achieve it.
10:04 rubenwardy Taoki: there's the source code on his GitHub, and there's also a forum topic. As explained in the video, it's not possible to have a proper spherical planet make of cubes, anyway
10:04 Taoki What's the link to the thread please, I'd like to follow it. And yeah it makes sense now that they explained it, I was actually not aware of that geometrical issue until now.

18:34 paramat jeija's spherical planet is a clever experiment but not practical, many issues and limitations. cubic planets are the way to go :)
18:40 Krock next challenge: display all nodes as a tetrahedron
18:45 paramat Taoki this is not the same but practical https://forum.minetest.net/viewtopic.php?f=11&t=15065
18:46 paramat and https://forum.minetest.net/viewtopic.php?f=11&t=7887
18:46 Taoki That's how I was thinking of making planets initially actually: No deformation of the voxel system, just spheres made out of cubes. Of course there's one huge drawback: Having actual working gravity around them.
18:47 Taoki With the default setup of the engine, gravity is still global in the down direction. Even if you make it go up, you can't conveniently flip the player's view and do other things.
18:47 Krock it looks amazing but doesn't work out well with the lighting system and gravity
18:47 Taoki Ah yes... the sun also shines from upward.
18:48 Taoki So a few engine changes would be needed to support it properly.
18:48 Taoki You also need to be able to set the liquid flow direction correctly.
18:49 Taoki With a few tweaks though, the engine could support something. You just need to be able to set the gravity of players / items (including camera direction) in a custom axis. If you have that, you can give the planet corners around which the gravity snaps... not an ideal fix but it would work.
18:50 Taoki The problem there of course is that if you reach the gravity age, you suddenly find yourself turned around and falling downward once you walk past a certain position.
18:51 Taoki You could of course make the gravity direction have a smooth falloff, but then the player will be pulled into diagonal directions across the blocks which will cause very nasty physics issues (imagine being pulled in between terrain blocks diagonally into the V shape they form)
19:01 jluc joined #minetest
19:05 paramat the game 'stellar overload' has cubic planets with gravity flipping through 90 degrees over the edges
19:19 AlexYst joined #minetest
19:25 exio4 how are you guys
19:39 Taoki paramat: Oh wow... that's a Minetest game? I didn't know you could already set the gravity to a custom axis.
19:40 paramat not a MT game
