Relevant Resources

these are things that are at least tangentially important..

• more density functions mod (this page will not be very useful without this mod. maybe some day i'll add vanilla fallbacks for missing features where possible?)
• not enough crashes (worldgen crashes when you do typos, and this means you don't need to do a full reload. very handy for speeding up testing a little)
• more density functions wiki
• density functions page on minecraft.wiki
• perlin noise function library thing

Language Guide

now, this will probably be familiar if you've ever done javascript or whatever.. basically you type maths expressions like x/64+0.5 and such, and the results of your expression are displayed on the square image, with cyan being -1 and magenta being +1. the panel shows all values from x=0-127 and z=0-127, with 3d density functions not being properly visualized currently (y defaults to 64, so you can at least verify that the surface looks sort of normal, i guess)

this language also supports a few maths functions, taken largely from more density functions. do note, it's NOT comprehensive. you can complain to me about it or download this webpage locally and add them yourself..

notable wierdnesses

• distance([x,y,z,...],[x,y,z,...]) - takes an abitrary set of two n-dimensional vectors, returning the euclidian distance between them.
• perlin(x,z,xScale,zScale) - scale is extracted for compatability with vanilla. i know there's more noise functions also, sorry for not implementing them..
