//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.

fix all the crashes with the new erosion algorithm
......but it doesn't look like it's functioning as intended just yet

Fix a ton of bugs but there are lots more to go..... 2020-08-21 13:27:40 +01:00

Start implementing snowball erosion algorithm.
There's still a long way to go - we're only just getting warmed up!

Start setting things out to implement erosion
First up, we're going to attempt to implement a snowballs-based 
algorithm.

os.clock() → minetest.get_us_time()
....how did I miss that :P

Centralise all command aliases
This should avoid any crashes on startup because worldedit.alias_command 
is nil too (strange!)

Also add aliases //naturalise and //naturalize

convolve: fix a bunch of bugs.
It's still behaving reeaallllly strangely though

Add //convolve command
....but it's all untested of course :P

Implement (untested!) manip interface on top of the raw convolutional code 2020-06-09 20:43:29 +01:00
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.
