I know that minetest uses Perlin Noise so just a little suggestion, that document http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf describes a Simplex Noise that is "better", in particular there are some few more prominent advantages of Simplex Noise, they are: 1) has a lower computational complexity and requires fewer |
| 14:03 |
waressearcher2 |
multiplications. 2) has no noticeable directional artifacts 3) has a well-defined and continuous gradient everywhere that can be computed quite cheaply 4) Simplex noise is easy to implement in hardware, and this is one of implementations of it http://www.itn.liu.se/~stegu/simplexnoise/SimplexNoise.java, wouldn't it be greate to have it in |
| 14:03 |
waressearcher2 |
minetest to speed up world generation ? or there are reasons it is not used in minetest ? |
| 14:11 |
|
leat2 joined #minetest-dev |
| 14:13 |
T4im |
simplexnoise is patented, so you'd have to use a similar but unpatended algorithm like opensimplex ;) |
| 14:18 |
waressearcher2 |
so, why not opensimplex ? |
| 14:41 |
Krock |
just add it ^^ |

to look into a performance issue on VE-Basic that apparently started a couple days ago |
| 18:13 |
T4im |
uh,.. have you already forgotten how it crashs and calculates wrong? :/ |
| 18:13 |
VanessaE |
apparently I have. |
| 18:14 |
VanessaE |
but I have to do *something* |
| 18:14 |
VanessaE |
these are production servers |
| 18:14 |
VanessaE |
I can't have them crapping out. |
| 18:14 |
T4im |
was there a problem with the fork/fix that I'm not aware of? :o |
| 18:15 |
|
Player_2 joined #minetest-dev |
| 18:15 |
VanessaE |
eh? |
| 18:18 |
T4im |
well you used "profiler" before, that's why I'm wondering, why you would prefer the built-in one with the known issues, again.. |
| 18:18 |
VanessaE |
oh, no I'm using the inbuilt mod_profiling |
| 18:18 |
VanessaE |
simply because it's already there. |
| 18:18 |
T4im |
ah |
| 18:20 |
VanessaE |
why hasn't yours been merged upstream yet? |
| 18:20 |
T4im |
shadowninja apaprently wanted to make his own rewrite |
| 18:21 |
T4im |
so 3 core devs ignored it, copied the abm labeling, made some (not all) of the bugfixes, but cleaned it up in a way that makes a merge impossible |
| 18:21 |
T4im |
so, I guess that's why I'm a bit latently disappointed with it all |
| 18:21 |
VanessaE |
sounds like you should rebase/rewrite it and re-submit it |
| 18:21 |
T4im |
there's nothing in the rewrite that isn't in my fork half a year earlier |
| 18:24 |
|

it's just now, that I wondered if there was some issue with it, that might explain this |
| 18:24 |
T4im |
anyway.. :) |
| 18:25 |
T4im |
I could check, which mod it was that crashed the built-in one for you, if you want.. that way you could possibly prevent it from crashing again |
| 18:29 |
|
luizrpgluiz joined #minetest-dev |
| 18:30 |
VanessaE |
nono |
| 18:31 |
VanessaE |
it's nothing at all to do with the profiler, per se., I just needed to get it running so I could track down a bad mod elsewhere |
| 18:33 |
VanessaE |
well, that's real fucking helpful: http://pastebin.ubuntu.com/12399398/ |
| 18:33 |
VanessaE |
:P |
| 18:33 |
VanessaE |
(default -> abm -> 3983865) |
| 18:34 |
VanessaE |
none of default's abms are labeled? |
| 18:37 |
T4im |
I don't think so, and only the rewrite (which is not merged into master yet) has the abm labeling |
| 18:38 |
T4im |
my version enumerates as a fallback if no label is there btw |
| 18:38 |
T4im |
perhaps that helps |
| 18:38 |
T4im |
to know it's the "5th abm" ;) |
| 18:38 |
|
red1 joined #minetest-dev |
| 18:43 |
Sokomine |
it might help already if it becomes visible if it's just one abm in particular or more or less split up amongst some |
| 18:43 |
T4im |
example output: https://gist.github.com/t4im/657c6d6a788659c5f8a0 |

splits up other functions too.. but since it can save to a dedicated, file the verbosity shouldn't be a problem |

it may be cg72's waterfall particles patch (for minetest_game) that is the culprit. |
| 18:57 |
T4im |
it certainly does a lot of unnecessary node lookups |
| 19:05 |
waressearcher2 |
T4im: can't node lookups be done on a separata core ? |
| 19:05 |
waressearcher2 |
I mean why not to make minetest multicore friendly |
| 19:06 |
T4im |
my point was, that it doesn't make sense to lookup a node and then look it up 5 times more |

also I'm halfway having a good cross-platform gulpfile, the problem is that it keeps rebuilding the Jekyll site on Windows |

one day, we'll use gulp, and benefit from Browsersync + Stylus + Jekyll all with one command. :-) |

How does minetest store the map? |
| 21:23 |
VanessaE |
sqlite |
| 21:23 |

aor leveldb |

depending on which backend you're using. sqlite is the default. |

-a |

how is that data organized in the database? There was a page on the dev wiki about it put i can't find it |

AHHH that documentation needs updated |
| 21:33 |
est31 |
this is wrong https://github.com/minetest/minetest/blob/master/doc/mapformat.txt#L44 |
| 21:34 |
red1 |
Why is that in mapformat? |
| 21:34 |
est31 |
that's a question as well |
| 21:34 |
red1 |
Shouldn't there be like worldformat.txt? |
| 21:37 |
est31 |
good idea |
| 21:40 |
red1 |
Where do I find the most up to date documentation? dev wiki or github? |
| 21:40 |
est31 |
varies |
| 21:41 |
est31 |
but we try to keep both up to date |
| 21:43 |
red1 |
When a client request a block what function is used to load it? |
| 21:43 |
red1 |
getBlockOrEmerge? |
| 21:44 |
est31 |
you mean that the client asks the server to get a mapblock? |
| 21:44 |
est31 |
there was such a protocol message once but it was deprecated |
| 21:45 |
red1 |
Yes |
| 21:45 |
est31 |
right now the server just sends the client mapblocks on its own descision |
| 21:45 |
red1 |
ohh |
| 21:45 |
est31 |
depending on where you are and where you look |
| 21:46 |
red1 |
what part of the code does that? server.cpp? |
| 21:47 |
est31 |
I think yes |
| 21:47 |
est31 |
but only because I know that server.cpp does that much |
| 21:50 |
est31 |
what I always do is to look up the protocol messages name in network/networkprotocol.h |
| 21:50 |
est31 |
and then to grep -r src the name |
| 21:52 |
red1 |
so search network/networkprotocol.h for it? |
| 21:53 |
est31 |
yeah. |
| 21:53 |
est31 |
there you find out that the message is called TOCLIENT_BLOCKDATA |
| 21:55 |
est31 |
then you cd to the source dir and do grep -rIn TOCLIENT_BLOCKDATA src |
| 21:56 |
est31 |
it gives you matches in clientopcodes.cpp and serveropcodes.cpp |
| 21:56 |
est31 |
those can be ignored |
| 21:56 |
est31 |
because they are only important for low level code |
| 21:56 |
est31 |
and for where the protocol message is handled by the recieving party (the client) |
| 21:57 |
* red1 |
realizes he is using windows |
| 21:57 |
est31 |
then there is a match at src/server.cpp:2144 |
| 21:57 |
est31 |
lol |
| 21:58 |
red1 |
blame it on Ubuntu and lubuntu hating my pc |
