  • 74733549df Various bugfixes and workarounds Now working in pure Lua! Some parts of the code are very hacky (e.g. noise) and the way new and old codes have been glued together is sometimes to be rewritten. But at least it works. Gaël C 2021-06-03 23:30:04 +0200
  • cb297af047 Add all code for generating a grid on world creation. Not tested ; will likely need much testing and bugfix. Gaël C 2021-06-03 20:08:57 +0200

  • 462942cc22 Use iterative finite differences for diffusion, instead of gaussian blur Allows variable diffusion coefficients variable_erosion Gael-de-Sailly 2020-12-27 13:46:25 +0100
  • 1b96f52e47 Decrease variations of parameter m Gael-de-Sailly 2020-12-27 13:45:24 +0100
  • 3ccb6932ad Implement simple tectonics. Uplift and subsidence are determined with a noise, at every iteration. There is no distinctive pattern like tectonic plates, just vertical movements disturbing rivers from their equilibrium state, and thus creating more diversity. More lakes and waterfalls especially. Gael-de-Sailly 2020-12-24 11:52:08 +0100
  • 32f3cd9925 Fixed 3D noise map, and removed catchment_reference Now K and m are determined independently. Alsoo removed debug plotting. Gael-de-Sailly 2020-12-24 11:46:45 +0100
  • ae46ada648 Use a class for noise map generation, and add a function for 3D slice of a 2D noise. Gael-de-Sailly 2020-12-22 20:50:45 +0100
  • 4b1d11dd73 Implement variable K and m erosion parameters For now noise parameters are hardcoded. Gael-de-Sailly 2020-12-22 14:55:49 +0100
  • c175f2bbf7 Document conf files old_master Gael-de-Sailly 2020-12-24 14:47:53 +0100

  • 85e545d5ac Fixed sea level variations Gael-de-Sailly 2020-12-24 13:09:08 +0100
  • e0aecdc3f3 Added a second method for local flow calculation. It is possible to switch between them using the 'flow_method' parameter. Gael-de-Sailly 2020-12-24 12:42:18 +0100
  • 83728cc932 Fixed lakes elevation There were sometimes missing water patches near a lake's edge, when the neighbour catchment area was lower. This commit allows to divide a cell into several mini-catchment basins, to fill only a part of it with water. Gael-de-Sailly 2020-12-22 18:34:30 +0100
  • 9ffa150263 Added function 'noisemap' to generate a noise map with a quite unified parameter set, and an option for logarithmic noise. For future use. Gael-de-Sailly 2020-12-22 01:44:03 +0100
  • 2a9335332b Added optional sea level variations for the simulation. This results in more varied coastline morphologies. Gael-de-Sailly 2020-12-22 01:11:43 +0100
  • 9b4a9b2516 Rework default erosion parameters, Fix ignored values of K and m, and changed processes order. Gael-de-Sailly 2020-12-20 18:51:44 +0100
  • 7529291ab4 For bounds.py (calculation of offsets), use the same data type as rivers Gael-de-Sailly 2020-12-20 18:48:10 +0100
  • b4f97bec61 For noise map seed: don't go over ±4096, to prevent rounding errors on coordinates (because noise library uses 32-bit floats) Gael-de-Sailly 2020-12-20 18:11:11 +0100
  • 3dc874a494 Added description of the algorithm + acknowledge the authors of the paper. Gael-de-Sailly 2020-12-05 14:33:40 +0100
  • f0dddee33c Lakes map: keep initial height (reduces file size) Lake height is calculated for every basin, and there is a lake if lake height is higher than ground height. If it is lower, there is no lake. In that case, it was previously raised to ground level, but since this can be done in Lua, we can write initial lakes height in the files. This has the advantage of reducing file size, since there are bigger areas of equal values, that are more efficiently compressed. Gael-de-Sailly 2020-12-05 14:24:50 +0100
