00:25 paramat       JDCodeIt yes 'scale' was used i old perlin functions for what is actually 'spread'. the newer noise functions use 'scale' to mean a scaling factor for the noise value (used togehter with 'offset')
00:25 paramat       *used in
00:25 paramat       perhaps the docs can be changed for consistency ...
00:26 paramat       will consider
00:26 JDCodeIt      Yep, I'll follow up with the wiki as well if we go that way.
00:28 JDCodeIt      Just on another thing... I'm having a heck of a time matching the perlin output with the biomes i see on the v6 map. Must be going off the reservation somewhere.
00:28 paramat       blend problems?
00:28 JDCodeIt      maybe - what is that 1/40 th part that gets added?
00:29 JDCodeIt      So I made a quick mod that lets me see the calculated perlin as I walk around the map
00:30 JDCodeIt      I would expect the main perlin noise to be pretty close: less than -0.4 in snowy areas and above 0.4 in the desert.
00:31 JDCodeIt      In lua I make a perlin object with mgv6_np_biome params. Then I use get_2d filling x=pos.x and y=pos.z - any other trick here?
00:33 paramat       mgv6 has, annoyingly, an offset added to the noise calculations
00:34 paramat       https://github.com/minetest/minetest/blob/187519407be5ca51db007d638857917ba53f1b6d/src/mapgen/mapgen_v6.cpp#L652
00:34 paramat       humidity is not offset though
00:34 paramat       so to match it in my meru mod i had to do https://github.com/paramat/meru/blob/0a1961a393dad919874ab49f14e35c163b8b83b9/init.lua#L143
00:35 paramat       mgv6 really is a pain, i try to ignore it as much as possible
00:36 paramat       'perlinMap2D_PO' is a special perlinmap function that takes an XZ offset into account
00:37 JDCodeIt      Passing these offsets in x/z is all you need ?
00:38 paramat       yes just as in meru mod, although that mod doesn't bother calculating humidity because it was written before the newer mgv6 6-biome system
00:39 JDCodeIt      Ok, I'll give it a whirl. Thanks for the help!
00:40 paramat       i don't think i've ever exactly mimicked the mgv6 biome blend, in meru mod you can see i just use a 'math.random()' to approximate the biome blend, as it's single-node dither
00:41 paramat       i admire anyone who can tolerate mgv6 stuff :)
00:41 paramat       i'd love to just remove it but of course we have to support old worlds
00:50 JDCodeIt      Can we help phase it out.. make v7 the default generator or something?
00:52 JDCodeIt      Results are better but not convincing. I added 150 to x and 50 to z.
00:53 JDCodeIt      I get the map settings: minetest.get_mapgen_setting_noiseparams("mgv6_np_biome")
00:53 JDCodeIt      Make a perlin: heat_perlin = minetest.get_perlin(np_heat_biome)
00:54 JDCodeIt      Get the noise at the modified position: heat_perlin:get2d({x = math.floor(t_pos.x), y = math.floor(t_pos.z)})
00:58 paramat       mgv7 is the default mapgen now =) but we promise to support old maps for a long time, many like mgv6
01:07 argyle77      How do I tell a node to use an animated texture?
01:09 JDCodeIt      I think default furnace has an example
01:11 argyle77      thx!
01:18 argyle77      Got it.  Workd.
01:44 JDCodeIt      paramat: where the +150 +50 empirically derived, or is it something in the code? My empirical results on a sample world show good match with terrain at +250 +100
01:49 argyle77      Is there any way to synchronize texture animation when you've got a bunch of nodes with the same animated texture?
01:52 argyle77      I'm guessing no, having seen how lava behaves?
01:56 paramat       synchronize animations across mapblocks? yes there's a setting but it doesn't work perfectly
01:59 paramat       oh 150 50 may have been for the older mgv6 biome and humidity spreads
01:59 argyle77      Should I bother with it?  Its an aesthetic thing, but I'm not hung up.
01:59 paramat       try xoff 0.6 * 500 and zoff 0.2 * 500 for 'biome'
02:00 paramat       argyle ask your eyes =)
02:00 argyle77      My eyes say it works better synched.  What's the setting?
02:01 paramat       the old 'biome' spread was 250 and the offsets for that spread were 150 50
02:01 paramat       somewhere in con'f.example
02:02 paramat       new offsets try 300 100
02:07 paramat       i think the sync setting may be a clientside thing, search the file with 'animation'
02:09 argyle77      ok thanks.  Not looking for a client side thing, prolly.
02:15 paramat       yes thought so :)
02:15 paramat       to match your noise, best disable mgv6 biome blend at first (it's ugly anyway)
02:17 JDCodeIt      we sure the humidity does not have offsets? reported perlin noise in desert was 0.6 and higher, which should be jungle
02:23 paramat       sure https://github.com/minetest/minetest/blob/187519407be5ca51db007d638857917ba53f1b6d/src/mapgen/mapgen_v6.cpp#L653

12:09 p_gimeno      VanessaE: ^
12:10 p_gimeno      alas, too late
12:10 ChimneySwift  wow
12:24 sfan5         first time i've been advertising of this kind on irc
12:24 sfan5         seen*
12:42 p_gimeno      it's been tested over the last few days, first Violet_T, then Linda_Wolfy, then sergiuslane and now minetest_test
13:05 JDCodeIt      Is this some sort of list of sources for content one might add to mods?
13:08 JDCodeIt      Updating the dev wiki on the get_perlin() function - there is reference to lacunarity but the formula does not show how this is used. Can we get an update to the listed formula in lua_api.txt?
13:45 Vapalus       Did someone already attempt to create a skybox using the actual map generator? I'm just asking out of curiosity
13:47 VanessaE      that spammer has been occasionally showing up in #reprap also.
13:47 VanessaE      sorry I was afk
13:47 VanessaE      Vapalus: actually yes, I want to say hecks was playing around with something like that
13:48 Vapalus       Ah, explains the -v in #minetest-dev
13:48 Vapalus       okay, because I was looking at the code yesterday, and it seems possible. Unless, of course, there would be problems with syncing the client and server
13:49 Vapalus       I doubt I can grasp the full concept of minetest by just looking at the map generator for a few minutes
14:04 p_gimeno      Vapalus: there was some recent discusion about how inefficient the minimap generator is, and hecks said he'd take a look
14:09 p_gimeno      http://irc.minetest.net/minetest-dev/2019-02-10#i_5493208 for the map generator, http://irc.minetest.net/minetest-dev/2019-02-08#i_5491797 about doing some rendering to the skybox
14:11 p_gimeno      oh, by map generator you probably meant the mapgen, not the minimap code, sorry
14:12 p_gimeno      the second link above still applies
14:12 Vapalus       map gen, not minimap. I'm not that far into the code :)
14:12 Vapalus       thanks
14:17 VanessaE      "<hecks>	entuland; I do some raytracing against the map's perlin noise and render it to the skybox"
14:17 VanessaE      so that's a yes. :)
14:54 entuland      I think he's messing with both things - the message above is about improving the appearance looking around IIRC
14:55 entuland      unfortunately that technique doesn't take in account terrain modifications
14:58 Vapalus       loading terrain modifications would be a bit much in the beginning, i presume, if you think that everything is stored serverside
14:58 VanessaE      sure.  he should first work on reviving the farmap code
14:58 Vapalus       farmap?
14:58 Vapalus       or farm map
14:58 VanessaE      farmap.
14:59 VanessaE      variable "resolution" renderer, I guess some compare it to octree.
14:59 VanessaE      the further away from the viewer, the more nodes are collected into and rendered as single cubes.
14:59 Vapalus       dunno if that's an octtree per se, but it's something that definitely sounds like a plan
15:00 Vapalus       it's more like a LOD model
15:00 VanessaE      celeron55 had it working at one time.
15:00 VanessaE      basically, 10 times the view range for the same fps.
15:00 VanessaE      I could see 1000m out, with good frame rates.
15:00 Vapalus       sounds more and more like LOD
15:01 VanessaE      it is kinda yeah
15:02 VanessaE      it was buggy, but it worked.
15:02 Vapalus       Thinking about it, that's either double the memory used (on the hard drive, I mean) or a hard drive killer
15:02 VanessaE      why'd it die?  idk.
15:02 Vapalus       because you
15:02 Vapalus       you'd need the lod saved, too
15:02 VanessaE      yes, it did that.
15:03 Vapalus       definitely sounds interesting
15:03 Vapalus       but it COULD be a problem with non-generated terrain, since it would have to be generated on-the-fly
15:04 VanessaE      I do seem to recall it having a slight mapgen performance hit,
15:04 VanessaE      and network protocol wasn't optimum either, I think
15:05 Vapalus       get the code running again, do a screenshot, post it on a flat earth society forum
15:06 VanessaE      heh
15:06 VanessaE      with HDX, yet ;)
15:08 Vapalus       The more I read it, the more it sounds like it'd need a lot of time being programmed
15:08 Vapalus       and I'm lazy as one can be
15:09 VanessaE      heh
15:09 Vapalus       That's the actual reason why I dislike challenges. I'd need to work.
15:11 Vapalus       Well, back to running Duke Nukem on an ESP32. Sounds easier.

21:22 paramat       JDCodeIt "Can we get an update to the listed formula in lua_api.txt?" which formula, link?
21:34 paramat       p_gimeno what's the problem with mushrooms?
21:35 p_gimeno      paramat: they need extreme darkness to grow
21:35 p_gimeno      to reproduce
21:36 p_gimeno      lighting <= 3 on midday
21:37 p_gimeno      this is happening in 0.4.16 by the way
21:38 p_gimeno      this mostly prevents them from growing naturally, you need a dark room to grow them
21:43 paramat       ok yeah intentional
21:44 paramat       it's to avoid them going crazy in naturally dark places in jungles
21:46 paramat       adds some work and challenge too
21:50 p_gimeno      challenge? to figure out how to grow them, you mean?
21:51 paramat       good point, players need to know darkness is needed
21:52 paramat       maybe some kind of essential info documentation is needed
21:53 p_gimeno      https://wiki.minetest.net/Brown_Mushroom mentions "in darkness"
22:21 JDCodeIt      paramat: get_perlin updated on the dev wiki - https://dev.minetest.net/minetest.get_perlin - have a look and let me know if something needs clarification or addition
22:27 paramat       ok. lacunarity is irrelevant to the formula
22:28 paramat       'noise = offset + scale * (octave1 + octave2 * persistence + ...'
22:39 paramat       wiki seems ok
