Starbeamrainbowlabs	fd5804dd9c	//erode: Finish the initial round of bugfixing, but I'm on the fence about it. ... Specifically, I'm unsure about whether I'm happy with the effects of the algorithm. Also, we convolve with a 3x3 gaussian kernel after erosion is complete - and we have verified that the erosion is having an positive effect at "roughening up" a terrain surface. It seems like the initial blog post was correct: the algorithm does tend to make steep surfaces steeper. It also appears that it's more effective on larger areas, and 'gentler' curves. THis might be because the surface normals are more conducive to making the snowballs roll. Finally, we need to decide whether we want to keep the precomputed normals as we have now, or whether we want to dynamically compute them at the some of request.	2020-08-21 20:59:50 +01:00
Starbeamrainbowlabs	997eb4d101	fix all the crashes with the new erosion algorithm ... ......but it doesn't look like it's functioning as intended just yet	2020-08-21 15:21:10 +01:00
Starbeamrainbowlabs	acb288b984	Fix a ton of bugs but there are lots more to go.....	2020-08-21 13:27:40 +01:00
Starbeamrainbowlabs	cdba38d37d	Start implementing snowball erosion algorithm. ... There's still a long way to go - we're only just getting warmed up!	2020-08-20 01:53:26 +01:00
Starbeamrainbowlabs	20ccf321ce	Start setting things out to implement erosion ... First up, we're going to attempt to implement a snowballs-based algorithm. Reference: https://jobtalle.com/simulating_hydraulic_erosion.html	2020-08-18 02:11:37 +01:00
Starbeamrainbowlabs	0afbba4deb	os.clock() → minetest.get_us_time() ... ....how did I miss that :P	2020-06-26 20:46:35 +01:00
Starbeamrainbowlabs	b8a5bec987	Centralise all command aliases ... This should avoid any crashes on startup because worldedit.alias_command is nil too (strange!)	2020-06-11 01:00:19 +01:00
Starbeamrainbowlabs	5232406dbb	Alias //flora to //bonemeal	2020-06-11 00:38:35 +01:00
Starbeamrainbowlabs	75a17ed64f	Add //layers command ... Also add aliases //naturalise and //naturalize	2020-06-11 00:38:16 +01:00
Starbeamrainbowlabs	d96f169950	It works! :D	2020-06-10 00:48:39 +01:00
Starbeamrainbowlabs	2dbbeef9c9	convolve: fix a bunch of bugs. ... It's still behaving reeaallllly strangely though	2020-06-09 22:00:56 +01:00
Starbeamrainbowlabs	868052f945	Add //convolve command ... ....but it's all untested of course :P	2020-06-09 21:11:34 +01:00
Starbeamrainbowlabs	6dac57c53e	Implement (untested!) manip interface on top of the raw convolutional code	2020-06-09 20:43:29 +01:00
Starbeamrainbowlabs	9b9a471aa8	Implement initial (untested) convolution system. ... Next we need to implement a worldedit function to handle fetching the manip data, calculating the heightmap, pushing it through this convolutional system, and saving the changes back again.	2020-06-09 01:21:32 +01:00
