-- More trees! 2013-01-20
--
-- This mod adds more types of trees to the game
--
-- Some of the node definitions and textures came from cisoun's conifers mod
-- and bas080's jungle trees mod.
--
-- Brought together into one mod and made L-systems compatible by Vanessa
-- Ezekowitz.
--
-- Conifers and Jungle tree axioms/rules by Vanessa Ezekowitz, with the
-- latter having been tweaked by RealBadAngel, most others written by
-- RealBadAngel.
--
-- License: WTFPL for all parts (code and textures)
--
-- snow biomes mod uses this code to make biomes:
--
-- local perlin1 = env:get_perlin(112,3, 0.5, 150)
-- local test = perlin1:get2d({x=pos.x, y=pos.z})
-- if smooth and (test > 0.73 or (test > 0.43 and math.random(0,29) > (0.73 - test) * 100 )) then
-- in_biome = true
-- elseif not smooth and test > 0.53 then
-- in_biome = true
-- end
--
-- We'll just save this for possible later use ;-)
