Starbeamrainbowlabs	1310dae884	Refactor: Split up terrain.lua, make subtable wea.terrain ... This is just the start, if my plans work out. The eventual aim here is to implement a generic Heightmap2D class, just like Vector3. This will make interacting with heightmaps much easier.	2021-12-31 02:42:32 +00:00
Starbeamrainbowlabs	db5d25d1de	//convolve: update matrix & kernel to use Vector3 ... A lot of the maths remains in the old style, but at least it doesn't take a zero-indexed table	2021-12-28 18:31:46 +00:00
Starbeamrainbowlabs	c6bae3b7e0	//erode river: fix redefining i in nested loop	2021-07-30 19:44:02 +01:00
Starbeamrainbowlabs	ecb846fcfe	//erode river: fix undefined global variable	2021-07-30 18:03:39 +01:00
Starbeamrainbowlabs	fa2c0642c1	Fix typo in comment	2021-07-18 20:11:10 +01:00
Starbeamrainbowlabs	db7b20d485	Refactor table functions into subtable of wea ... Also, you can return a value from dofile()!!!! This changes everything.	2021-06-28 00:56:29 +01:00

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
