In the first article I showed how the Marching Cubes algorithm works in 2d.
In this tutorial, I cover how it can be extended to 3d.

Marching Cubes Tutorial
In Minecraft, you can dig in any direction – removing a block at a time with well defined edges. But other games manage to destruct terrain smoothly, without all the blockiness of Minecraft.
The following tutorial in Marching Cubes, a technique for achieving destructible terrain, and more generally, creating a smooth boundary mesh to something solid. In this series, we’ll cover 2d in this first article, follwed by 3d in the next , and Dual Contouring in the third. This last is a more advanced technique for achieving the same effect.
Tileset Roundup
Following my development of Resynth Tileset, I’ve been doing some thinking on the nature of tilesets, and the possible ways to auto tile them – that is, to paint tiles as is with a brush and letting the computer do the tile selection. Let’s review a few possible ways of doing so.
Just to be clear, I’m only interested at the moment in square, non-rotatable tiles. Rotation is another discussion, but excludes the more interesting tilesets. Adding alternative tiles is also not considered, though it is pretty easy to add in.
Resynth Tileset
I’ve released a GIMP plugin on Github that allows you to create large tilesets really easily, like this one, based off of the Resynthesizer Plugin.
