Gael-de-Sailly	9700e948b9	Position should be strictly beyond river threshold to be a river ... Prevents some wrongly placed water pixels.	2020-04-14 21:54:05 +02:00
Gael-de-Sailly	55725ad94b	Re-organized the code. All polygon-related calculations go to polygons.lua.	2020-04-14 21:11:54 +02:00
Gael-de-Sailly	43211fc31b	Removed useless functions get_point_location and geometry.area	2020-04-14 20:26:15 +02:00
Gael-de-Sailly	14163681cc	Use settings from minetest.conf	2020-04-14 18:40:51 +02:00
Gael-de-Sailly	af7a7ce26d	Compress data files (reduces size by a factor 3-4)	2020-04-13 15:59:34 +02:00
Gael-de-Sailly	da98a538bb	Draw outer corners of river turns.	2020-04-13 15:01:54 +02:00
Gael-de-Sailly	1adb4fbece	Added an offset of 0.5 on terrain elevation ... This prevents rounding errors and improves interpolation on nearly flat areas	2020-04-13 12:27:24 +02:00
Gael-de-Sailly	13d3e70b66	Implemented variable river width. ... Also changed the river data exported by terrain_rivers.py. They will not be compatible with what's generated by older versions.	2020-04-13 12:15:10 +02:00
Gael-de-Sailly	4b63ed371e	Add more information in the polygon table	2020-04-13 10:31:38 +02:00
Gael-de-Sailly	eba90803fe	Removed useless debug print	2020-04-13 10:01:23 +02:00
Gael-de-Sailly	34de4269ee	Add directly a reference to the polygon table in the polygon list, instead of adding an index	2020-04-13 09:54:04 +02:00
Gael-de-Sailly	56cebecb13	More robust and faster code for grid twisting on the Lua side. ... At chunkgen init, build a list of the polygons instead of calculating them for every node.	2020-04-13 09:27:41 +02:00
Gael-de-Sailly	b7c6f71635	Implemented grid twisting. Still many possible bugs, potentially clumsy implementation, but it seems to work.	2020-04-13 09:27:41 +02:00
Gael-de-Sailly	0bf351b2f6	Initial commit: working example using a basis of Simplex noise and implementing river flowing, lakes, and erosion	2020-04-09 21:15:41 +02:00
