00:08 paramat just spotted 2 errors, see comments, then i'll merge it
00:11 rubenwardy joined #minetest-dev
00:11 sofar paramat: cool. I have no problems trying to get it right and hitting another test run with that.

01:21 sofar paramat: is there a way in lua to determine the textual name of the biome for a node?
01:22 paramat for a co-ordinate?
01:22 sofar pos, yes
01:23 paramat not sure, you've found the 'mapgen object biomemap'? but that's only available in 'on generated'
01:24 paramat that only gives biome id number
01:24 sofar yeah I'm looking at it from a post-mapgen perspective
01:24 paramat ah
01:24 sofar well you can unmap all the id's if you know all the names
01:24 sofar so that's not too hard
01:24 sofar clumsy, but doable
01:25 sofar in order to help mapgen mods, I was wondering if it would be nice for my inspector mod (for instance) to display biome name for an position. Since that way it's easier to track down where from a decoration came.
01:26 sofar minetest.get_biome_id(biome_name) already exists
01:26 sofar should just expand it with minetest.get_biome(pos) and minetest.get_biome_name(id)
01:27 sofar anyway, not so important
01:27 paramat mgv7 has 'getBiomeAtPoint(v3s16 p)' it would need an api to access it
01:28 paramat otherwise model the biome points and voronoi diagram in lua
01:28 sofar getBiomeAtPoint() sounds great
01:28 sofar just what would be needed for that
01:30 sofar interesting
01:31 sofar paramat: minetest.registered_biome is mentioned in the lua_api.txt but it's never properly defined
01:33 paramat ah yes some biome docs may still be missing, i need to do that then
01:34 jin_xi is there a way to get biomes in biomes? i mean like hardcore jungle biome which only can appear inside of jungle for example
01:34 sofar sorry, wasn't an attempt to create more work :(
01:34 sofar jin_xi: yes, all possible... mapgen.lua has plenty actual examples
01:35 paramat a biome within another is difficult, voronoi diagrams tend to produce biomes 'beside' each other
01:35 paramat but extra jungle biomes are possible
01:35 sofar you'd likely have to create 3 or 4 encircling ones, but a sandwich model may also work for you
01:36 sofar jungle | hardcore tarzan | jungle
01:36 paramat yes
01:36 paramat the system can have up to 256 biomes
01:41 sofar https://gist.github.com/sofar/a0b77a44d318239a3b9b
01:41 sofar paramat: close, but it's not in BiomeManager?
01:41 * sofar does C++ hide-and-seek
01:41 sofar here function function
01:45 paramat maybe it's only accessible during mapgen
01:45 paramat very likely
01:55 sofar doh
02:08 sofar paramat: I feel like we've had this exact discussion before
02:28 paramat possible, i get asked this often
02:46 paramat left #minetest-dev
03:47 blert joined #minetest-dev
03:51 blert having build issues... I build MT and it works fine on 3 of my 4 laptops. On the fourth it fails to find OpenGL v1.2 and runs as v1.1, a krock/sfan5 build works fine on the same laptop. Any ideas?
03:52 sofar same exact binary on all 4 systems?
03:52 blert yup
03:52 sofar so either the local driver is different or the local hardware
03:54 blert hardware is different on all four machines. I tried building on the problematic laptop itself with the same result. But downloaded builds (krock/sfan5/official) work fine.
03:59 sofar what kind of hw is the problematic box?
04:01 blert an Intel p950 with Intel HD video. never had any issues with it running MT before. All my MT probems started after an all encompasing upgrade to Win10.
04:02 sofar I wonder if you just have to install an old DX version
04:02 blert Would that effect OpenGL not being detected properly?
04:04 sofar I'm no windows user, but it smells like a software support issue. maybe getting DX working is easier than trying to figure out what OGL support is missing?
04:05 sofar why not put linux on it?
04:05 sofar :^)
04:05 sofar sorry, that's cruel of me.
04:06 blert it's my son
04:06 blert ..'s
04:06 sofar oh, then it just builds character!
04:07 blert need to have windows on for school programs. I home school both my kids and linux does not have the software I need. We tried once and it didn't work out.
04:09 blert I'm going to try to find a different driver for the video but it still make me wonder why other people's builds work fine but mine do not.
04:13 RealBadAngel but why win 10?
04:14 blert not buy... all four laptops were good for the free upgrade, they all has 8.1 which is just a nightmare to use.
04:15 RealBadAngel in that case i would rather downgrade to 7
04:15 sofar I had to upgrade a box from 7 to 10 recently
04:15 RealBadAngel 10 is even more like a nightmare
04:16 sofar 7 home premium only supports 16gb ram, and I have 24gb ram in that box :(
04:16 blert usability is much better and back to what xp/7 was
04:17 RealBadAngel blert, youre building win releases on your own?
04:17 blert yes
04:18 RealBadAngel what about needed libs?
04:18 blert all accounted for
04:18 RealBadAngel i mean dll's
04:18 RealBadAngel you can try to copy them out of working build
04:23 blert grabbed sfan5's build, as I think it is a minGW build, and tried. No joy, Procedure Entry Point error
04:24 MyTeke_ChrisWMas I wonder, which Minetest build would be Supported on NetBSD 6.1.5?
04:25 blert Thanks for the help folks. I am putting this away for the night. Going to try building Irrlicht on the offending laptop in the morning and see if that helps

13:40 VanessaE give it time.
13:40 VanessaE sooner or later it'll replace X.
13:45 celeron55 you just need a wayland module on systemd
13:45 VanessaE heh
13:45 celeron55 when you have wayland/systemd in place of X/gnu/linux
13:45 celeron55 then*

19:59 Soni can we get an "User Expeirence/UX" issue label?
20:00 rubenwardy This is Minetest. User experience isn't really considered ;)
20:01 Soni rubenwardy, and that's exactly why I want the label
20:02 Soni it'll encourage UX to be considered
20:02 rubenwardy hopefully
20:02 rubenwardy and a UX subsystem would be nice - do we still do subsystems?
20:03 Soni this needs the "UX" label: https://github.com/minetest/minetest/issues/3204

21:48 paramat can anyone review https://github.com/minetest/minetest/pull/3523 'Improve speadLight and updateLighting performance'?
21:49 sapier I'll have a look at it
21:50 sapier hmm didn't someone replace vector by set for exactly same reason in other parts of minetest code?
21:54 paramat maybe gregorycu did elsewhere
21:56 exoplanet joined #minetest-dev
21:58 sapier I've written some comments to it, most of them minor
21:58 sapier I haven't tested if it really increases performance
22:05 paramat thanks

22:23 sofar joined #minetest-dev
22:27 paramat gregorycu and myself have been testing it thoroughly
22:28 sapier I can't proof this but imho prereserving should be the most important factor in this performance boost. if this is true size of prereservation would be  a relevant factor in it too
22:35 paramat ok
