realterrain v.0.0.5

A Minetest mod that brings real world Terrain into the game (using freely available DEM tiles). Any image can actually be used.

use any image any bit-depth (suggested to convert to greyscale first):

Supplied heightmap and landcover files:

Rock strata:

Settings tool (Realterrain Remote)

Biomes tool:

Trees and shrubs:

Slope analysis:

Aspect analysis:

Dependencies:

• You must have imageMagick and MagickWand installed on your system
• Mod security disabled

Instructions

• install the dependencies and the mod as usual
• launch the game with mod enabled, default settings should work
• use the Realterrain Remote to change the settings, or
• edit the mod defaults section
• create greyscale images for heightmap, biomes, rivers and roads if desired (heightmap is required) these should be the same length and width. Biomes image should be 8-bit and use pixel values from 0-9 to match the biome numbers, which makes it hard to paint them visually (working on this issue), roads and rivers can be any non-zero value.
• after you change settings exit the world and delete the map.sqlite in the world folder (the Delete button is experimental)
• enjoy!

Upgrading:

• delete the realterrain.settings file in the world folder, or just create a new world

Next steps:

• allow for placement of buildings and other structures via .mts import
• allow DEMs to tile according to standard naming conventions, or explicitly
• allow output of heightmap and land cover to image files
• admin priv for using the settings tool
• add more raster analysis modes
• allow raster symbology to be customized in-game

Changelog

0.0.5

• improved raster modes symbology and added "aspect"
• made the biome form fully clickable (image buttons and dropdowns)
• added a static water node
• removed dependency on luarocks
• biome cover image pixel values are used directly, not in brightness ranges (8-bit assumed)

0.0.4

• select layer files in game from a dropdown
• vertical, east, and north offsets
• in-game biome settings
• trees and shrubs in biomes

0.0.3

• switched to luarocks "magick" library
• included a biome painting layer, broke the "cover" layer into roads and water layers
• added the files used to the settings tool
• added strata for under the ground
• in game map reset, kicks all players on reset, deletes map.sqlite file

0.0.2

• switched to lua-imlib2 for support of all filetypes and bit depths
• supports downloaded GeoTIFF DEM tiles
• improved landcover
• added a tool, Realterrain Remote, which allows for:
• in game settings for initial tweaking (still requires deleting map.sqlite in world folder for full refresh of map)
• changed orientation of map to top left corner
• code cleanup, smaller supplied image files, screenshot and description for mod screen

0.0.1

• direct file reading of 8 bit tifs
