Hi all!

My try to make a simple marching squares in Lua.

How I can understand that this lines must not crossing?

Maybe helpful https://www.boristhebrave.com/2018/04/1 ... -tutorial/

Again just isolines lua, not isobands.

Actually, it's not marching-squares, it's marching-triangles.

Reworked version of marching squares, based on this tutorial: https://www.youtube.com/watch?v=0ZONMNUKTfU

Nice, the marching triangle(4th one) really looks like an actual contour map.
What are marching squares used for though?
I only know of using it to align(?) tilesets so that they look natural.

It was a way to make a nice smooth smog for Factorio mod. The old smog was (is) too squarish.

Wow, that really is an improvement!

Hahaha, you know when colors blend together - you can see the natural blending points?
It's like.. you manually built those instead of writing bumps that have noise.

So, isolines and isobands are solved!


Here
isoline is one segment, maybe two segments in tile.
isoband is a polygon for each tile, the list of them (or no polygon in tile).

Press arrows to scale, move noise with mouse or change isoheight with mouse wheel.
